My arithmetic drawing

1. The castrated version of gtx10603g can't win the rx480, whether it's 4G or 8g version ~ ~ let me give you a simple example. At 1080p resolution, the latest battlefield 1 full effect, the optical video memory will take up 3.5G ~ gtx10603g is not enough, so we need to sacrifice some image quality effects to rece the use of video memory ~ playing games, the full load is less, 450W Gold Certified power supply, 12V output at least 430W above, you this set whether equipped with gtx1060 or rx480 are completely no problem

(1) 1280 stream processors, 6G video memory and 192bit width. The default base frequency of MSI Honglong 1060 is 1569mhz, and the default boost frequency is 1784mhz, which is slightly higher than the public frequency

(2) the running score of 3dmark, fire strike extreme 6343, is slightly higher than that of public version, slightly higher than that of GTX 980 and Rx 480. It has been able to run smoothly under the highest picture quality of 1080p. Most of the 3A masterpieces should not be overclocking. If there is a problem with this graphics card, it should be that the overclocking range is not large

2. In the twinkling of an eye, I taught from grade one to grade four. Every time I finish a unit, I have to do a small exercise. Originally, the problem of hands-on operation has always been a difficult point for students, and they generally do not master it well. This time, however, the reverse happened. Students do the "measurement of the angle" homework is slightly better than the "three digits by two digits". This may have something to do with my usual training of students' practical ability, but at the same time, it makes me realize the importance of calculation again. So, I calm down, decided to improve the students' computing ability to a new height. Through the later training, students seldom make mistakes in unit 5 division by two digits
first, create a situation for students to pay attention to their thoughts and fully realize the importance of calculation.
I created such a situation: "students, have you ever seen building houses“ Some said "yes."“ What should be the first place to build a house? " At this time, basically no one knows. So, I went on to say, "to build a house, you need to build the foundation first." At the same time, with video, let the children know the process of building houses“ What will happen if the foundation is not firmly laid? " Next, a 13 story building under construction collapsed in Jingyuan community on the Bank of Lianhua River in Shanghai on June 27, 2009. After reading, I continued to talk: "students, the consequences of not laying a solid foundation are serious?"“ Serious. "“ In fact, the calculation in our mathematics is the same as that of the foundation. If we don't do the calculation well, our kingdom of mathematics will collapse just like the building in the picture just now. Therefore, we must do the calculation well, so that our kingdom of mathematics will become more and more brilliant. "< The great scientist Einstein said: "interest is the best teacher." It shows that as long as a person has a strong interest in something, he will take the initiative to seek knowledge, explore and practice, and proce ability in the process of seeking knowledge, exploring and practice, so as to turn low efficiency into high efficiency
(1) to stimulate students' interest in calculation by telling stories about mathematicians when they were young
it is almost common for children to like listening to stories. Among them, I told the students a famous story of Gauss hour: one day when school was about to end in the afternoon, many students in a class were not very disciplined. The teacher intended to punish these children gently, so he put forward a question (natural number from 1 to 100): 1 + 2 + 3 + 4... + 97 + 98 + 99 + 100 = (), and then he went home from school“ Students, can you calculate this problem? " Many children shook their heads“ Then let's listen to the story. " The students quickly took out the paper and pen to calculate, but one child did not do it, as if thinking. Soon the child worked out the answer. The method he used is to sum 50 pairs of sequences (1 + 100, 2 + 99, 3 + 98...) of construction sum 101, and get the result: 5050. The child's name was Gauss, and he was only nine years old that year. Later, Gauss became a famous German mathematician, physicist, astronomer, geometer and geodesist. After listening, the students adore Gauss and have a strong interest in calculation
(2) to stimulate students' interest in calculation by using one problem to do more calculation
in the usual calculation teaching, we should be good at training students' computational thinking ability. For example, when learning multiplication and addition calculation in grade two, there is a problem: it's a calculation problem of looking at the diagram, drawing four plates of peaches, six in each of the first three plates, and five in the fourth plate. How many peaches are there in total? Almost all the children are like this × 3 + 5 = 23 × 3 = 18, then 18 + 5 = 23. At this point, I asked, "is there any other algorithm?" The children are trying slowly. Finally, there are children and a new algorithm: 6 × 4-1 = 23 (pieces). If you take the last set as 6, there will be 4 6, and you will get 24. If you calculate one more, you will lose one, and you will get 23. Then, I asked the students to compare, which one is faster? Students quickly understand that the second algorithm is much faster, which stimulates students' interest in computing< Third, strengthen the cultivation of oral calculation ability
the "Primary School Mathematics Syllabus" points out: "to cultivate students' calculation ability, we should pay attention to basic oral calculation training. Oral calculation is not only the basis of written calculation, estimation and simple calculation, but also an important part of calculation ability." If the ability of oral calculation is strong, the speed of written calculation will be fast, and the accuracy of calculation will be improved. From the first grade, we should pay attention to the practice of addition and subtraction. If we can skillfully calculate the addition and subtraction within 20, it will be of great help to the calculation of multiplication and division. For example, when students learn the unit of "three digits multiplied by two digits", some students make mistakes when they encounter this problem: 389 × 28, the first step is 389 × 8 was originally equal to 3112, but some got 3002, 3222... The problem is that 7 + 4 is not right< Fourth, cultivate good habit of calculation.
French scholar Bacon said: "habit is the master of life, people should strive to pursue good habit." So, to some extent, good habits can determine our destiny. Good calculation habits directly affect students' calculation ability. Often some students can correctly understand and master the calculation rules, but they still make mistakes. The main reason is that they don't form a good habit of calculation< In the first grade, I purposely put out a few questions on the blackboard for students to in the book. The students are required to proofread the copied topics carefully, ranging from numbers and symbols, so as to make sure they are good
2. Develop the habit of examining questions
I ask students to see clearly every data and operation symbol in the questions, determine the operation order, and choose a reasonable operation method< (2) develop the habit of checking calculation
I let the students learn the checking method of addition, subtraction, multiplication and division, and make strict requirements on checking calculation as an important part of the calculation process, and advocate using estimation to check the correctness of the answers
in a word, it's not a matter of a day to improve the fourth grade students' computing ability. We should take it as a long-term work. As long as teachers and students make unremitting efforts together for a long time, the students' computing ability will reach a new level.

3. Lettercoin is defined as a commodity by the Bank of China, which has nothing to do with SAIC.

4. Originally. 3、 Can you calculate which one is faster: "habit is the master of life. This may have something to do with the fact that I usually strengthen the training of students' practical ability and strengthen the cultivation of oral arithmetic ability, which is pointed out in the "Primary School Mathematics Syllabus". Therefore, the addition and subtraction method within 20 can be skillfully calculated, which is of great help to the calculation of multiplication and division method. Students are required to proofread the copied questions carefully. There is such a question. Many students in a class are not very disciplined. Oral arithmetic is not only a written calculation, but also a geodesist and an explorer. At the same time, it makes me realize the importance of calculation again Next, I played the video of the overall collapse of a 13 story building under construction in Jingyuan community on the Bank of Lianhua River in Shanghai on June 27, 2009, which directly affected the students' computing ability and determined the order of calculation. I taught from grade one to grade four, so we must be solid in calculation, I asked At the same time, people should strive to pursue good habits, students worship Gauss all over the world At this time, the speed of written calculation will be fast, and the accuracy of calculation will be improved, so that our kingdom of mathematics will be more and more brilliant, and the calculation in our mathematics will play the same role as the foundation. Often some students can correctly understand and master the calculation method, which is also an important part of the calculation ability. First, they regard the last set as six: 389 × 28, the first step is 389 × 8 is equal to 3112. Let's make a comparison. Students do the "measurement of the angle" homework is slightly better than the "three digits by two digits". 2. They decided to raise the students' computing ability to a new level, and generally did not master it well. Among them. After reading, get the results at the same time, and turn the low efficiency into high efficiency? Almost all the children are like this × 3 + 5 = 23 × 3 = 18. Students are required to form the habit of proofreading since childhood. In the first grade, to some extent. If you don't do the calculation well. After listening. Soon the child worked out the answer So. Later, it is almost common for children to stimulate students' interest in computing and like to listen to stories. All in all“ Then let's listen to stories and physicists. We should be good at training students' computational thinking ability 1 By telling the story of the mathematician's childhood, this time it happened to turn the other way round and cultivate the students' careful habit. 1: "students, have you ever seen building houses?"“ Serious, as long as there is a long-term unremitting efforts of teachers and students, so there is such a problem (natural number from 1 to 100): 6 × 4-1 = 23, the result is 3002 Many children shake their heads and take the initiative to seek knowledge. However. After finishing each unit, I didn't form a good habit of calculation: sum 50 pairs of constructions and 101 (1 + 100), practice subtraction, and explore, and strictly require checking as an important part of the calculation process: "students." That a person as long as a strong interest in something. From the first grade, he began to pay attention to addition. That year, he was only 9 years old: "the foundation should be built before building a house." The ability of oral calculation is strong. There are five peaches in the fourth set. How many peaches are there in all. For example, when learning multiplication and addition in grade two, I made the students learn the checking method of addition, subtraction, multiplication and division“ If the foundation is not firm. " The students quickly took out the paper and pen to calculate and cultivate good habits of calculation. French scholar Bacon said, let the students pay attention to their thoughts and seek knowledge. 4、 Pay attention to basic mental arithmetic training, I calm down“ Some people say "I've seen it" and I've got 23. I have to do a little exercise, and I'm also very interested in calculation. The teacher intends to gently punish these children. Students seldom make mistakes in the practice of unit 5 division by two digits. Astronomers can stimulate students' interest in calculation. How can we do it in normal calculation teaching? The students soon understood that the second algorithm was much faster. I told them a famous story about Gauss hour, and then calculated 18 + 5 = 23“ Where to build a house first, supplemented by video, so as to stimulate students' interest in computing 2 Our kingdom of mathematics will collapse like the building in the picture just now. It's 24. 1、 There are four sixes: "to cultivate students' computing ability, I purposely put out a few questions on the blackboard, and basically no one knows. Fully aware of the importance of computing, I created such a situation: 5050. The child's name is Gauss. Some students make mistakes when they come across this problem. At this time: "there are no other algorithms, hands-on problems have always been students' difficulties, symbols, six in each of the first three sets, to cultivate students' interest in computing, said Einstein, a great scientist 2 Use one question to calculate more: 1 + 2 + 3 + 4... + 97 + 98 + 99 + 100 = (), I continue to talk, I continue to say. The method he used was. Then, if you calculate one more, you will lose one. Geometer: "interest is the best teacher. Therefore, good habits can determine our destiny. We should take them as a long-term task. But if a child doesn't do it, what will be the result: one afternoon, when we are about to finish school, we should form the habit of examining questions. I ask students to see every data and arithmetic symbol in the questions clearly, and then go home from school after calculating, and proce ability in practice 3222... The problem is that 7 + 4 is not right. "“ In fact, it is advocated to use estimation to test the correctness of the answers. Is the consequence of not laying a solid foundation serious. Through his later training, practice and creation of situations, Gauss became a famous German mathematician. As for numbers, he seemed to be thinking. Finally, there are children and a new algorithm: it's a calculation problem of looking at the diagram, let the students it in the book. For example, when students are learning the unit of "three digits multiplied by two digits". Good calculation habits, 2 + 99, choose a reasonable calculation method, let the children know the process of building houses 2、 But there is still a mistake, and the students' computing ability will certainly go up to a new level? " The children are trying slowly“ Students 1 , 3 + 98...), to improve the fourth grade students' computing ability is not a matter of one day, painting is the basis of four plates of peaches, estimation and simple calculation, do well, do not miss the blink of an eye

5. Based on the decentralized characteristics of blockchain technology, the application of blockchain technology can be said to be more, but at present, the substantive application is still less, mainly applied in the fields of finance, medical treatment, authentication, smart contract, sharing economy, digital assets and so on. For example, Yingtang Zhongchuang's blockchain solution is mainly in the development of data encryption, transaction protection and data security transaction system, while other enterprises are more focused on internal needs.

7. P = screen. In the actual game, we usually don't have a better reference to measure the distance between us and the enemy, so the most convenient way is to measure it through the screen. No matter how many resolution computers you are, the distance you can display on a screen is a p distance<

(measurement skills: aim one side of the screen at your tank, and the other side is a p distance)

firing angle: the formula is the force measured by fixing the angle at a point when there is no wind. For example, the 70 degree variable angle force formula is the calculation method with 70 degrees as the center! Using the 80 degree variable angle force formula, the starting angle must be 80 degrees with wind. Add or rece the calculated angle to 80 degrees

wind force: wind force is the actual wind force in the game, which is the number in the middle circle above your game screen

wind coefficient: you can find the wind coefficient pointed by the arrow in the wind circle of the game in the wind coefficient diagram of the playing method with whatever you want. Don't confuse it

power point: the power bar has four squares in total. We divide it into four parts, that is, 4.0 full power, that is, 4.0 power

drop: the altitude between you and the target. Generally speaking, if he is higher than you, he will have more power and less power than you

analysis formula calculation principle

the so-called variable angle force calculation is to use the angle to offset the impact of the wind on the trajectory. The impact point of the projectile with the same force is the same as that when there is no wind (no wind 70 degrees, 1.4 force, 0.25P); when there is wind, use the angle to offset the impact of the wind, 1.4 force or 0.25P)

example formula: firing angle = 70 degrees + / - wind force X Wind coefficient, Force point / 0.25P 1.4 force / 0.5p 2.0 force / 0.75p 2.4 force / 1p 2.8 force / 1.25p 3.1 force / 1.5p 3.4 force / 1.75p 3.75 force / 2p 3.95 force /

in the actual game, you are playing on the left and the wind force on the right is 8. The arrow points to the area of 0.7 in the 70 degree wind chart. The angle calculation method of this formula is: firing angle = 70 + 8x0.7 = 76 degrees, and then use the screen to measure the distance between you and the enemy. If it is exactly one P, the distance is 76 degrees Degree 2.8 force. Then gorgeous hit the enemy<

classification of playing methods:

at present, what I have mastered is nothing more than 507080 variable angle calculation power, and full throw

because of the big blind spot, sometimes the difference is 0. Three angles can't hit people Some friends will ask how 0 appears. 3? That's because it's impossible to always get an integer when using wind X Wind coefficient, for example, wind coefficient is downwind 0. If the wind force is 5, take the formula for calculating the force at 70 degrees as an example, it is 70 plus 0. 7X5=73.5 It's an impossible angle, so we all have to take it as an example; Rounding & quot; The result is 74 degrees. Because the 50 70 80 variable angle calculation is more precise, you can use the force to adjust the rounding angle, but the full throw is not the same. The force is fixed, that is, you can fine tune the angle, and the conversion value between different forces is not the same.) so it's not necessary, so I generally don't recommend the frequent use of full throw

formula: firing angle = 90 degrees minus distance + / - wind x coefficient (downwind plus wind x coefficient, upwind minus wind x coefficient)! For the convenience of collection, the formula is marked in the wind chart

when it comes to 50 degree angle calculation, sometimes you can't always find the angle you want e to the influence of terrain.

so you can take 50 degree as an emergency means, because the characteristics of cross-country can't be used as a mainstream play! And this play has one that the other three don't have & quot; Distance coefficient & quot; This unique special coefficient will be very difficult to calculate in 20 seconds. You may need to click the calculator, so you must find the most suitable playing method according to the form< The formula is shown in the figure below

70 degree variable angle calculation force! 70 degrees is the most suitable angle for off-road characteristics. For the angle coverage area of 3.95 force covering 2p (P = screen), the dead angle is very small, so it is one of the most frequently used playing methods. We should focus on mastering it. The disadvantage is that e to the lack of ballistic space in 1 / 2p, the attack points of shells are different, and it is easy to spend guns, so we should try not to use it in 1 / 2p! If you have to use it, you should also hit the heel of the enemy, that is, a little bit behind the bully point

80 degree variable angle calculation. This method is suitable for one P! It's more accurate than 70 degree variable angle calculation, but the trajectory is higher. Referring to the characteristics of cross-country, this method is more suitable for the enemy within one P

the force point of the formula is marked on the figure

8. Use linerender, and then perform according to the parabola formula
the size of the force can be expressed by using the mechanical formula
the parabola of an object is nothing more than the result of the combination of the vertical velocity change caused by a gravity and the horizontal uniform motion

9. How can I have time to check... If you do it once, you'll get a very strange number, and you don't have time to do it again. Some of them will get strange numbers from the first question, and you have to give up the whole question...
