BTC pictures
Novice first of all to know how to calculate your cost, recharge, trading, cash, there are fees. At least you can understand the K-line. There are a lot of people on the K-line. You can look at it casually and understand it. You need to be risk aware. bitcoin is a high-risk and high profit investment. It may double overnight, or BMW may become a bicycle overnight. At the beginning, we suggest a small amount of investment
but it's hard to get bitcoin for indivial mining, so it's basically large-scale mining, and you need to cooperate with the mine pool. So if you still want to make money by mining, at present, the most suitable mining method is cloud mining or mining machine hosting. After all, the era of single person mining is over
bitcoin is a reward for the answers generated by the complex calculation of computer technology. There is no channel to download it. There is a wallet to save the address
Chinese currency pi
bitcoin is actually an e-coin data coin proced by P2P batch software, which belongs to a network virtual asset so bitcoin is also called bitcoin. It is generated by a set of cipher codes through complex algorithms. This rule is not interfered by any person or organization. Anyone can download, run or participate in the manufacture of bitcoin. One of the biggest characteristics of bitcoin is that it cannot be forged< you can make money in the bitcoin market by investing time and money
when you spend time on websites, you can visit these websites every few minutes to get a small amount of bitcoin. Therefore, we can do this if we have time. If you want to earn more, you should invest money in the early stage. Bitcoin also has a special casino, so you can earn more by luck

the first one is the spring oscillator model. When the vibrator moves to the farthest away from the equilibrium position, the velocity is zero and the kinetic energy is zero. The mechanical energy is the elastic potential energy, and the size is
etotal = EP = 0.5ka2
when the spring vibrator moves to the equilibrium position, the spring type variable is 0. According to the conservation of mechanical energy, Vmax = a √ (K / M)
in the above formula, K: Spring progress coefficient.
A: amplitude; m: The second one is simple penlum model. When the penlum ball moves to the highest point, the velocity is zero and the ball has only gravitational potential energy. The size is EP = MGL (1-cos) θ), θ When the ball moves to the equilibrium position (the lowest point), the gravitational potential energy of the ball is all converted into kinetic energy, so the velocity at the equilibrium position is the maximum θ)= 0.5mv2max
the solution is Vmax = √ (2GL (1-cos) θ))< br /> cos θ= √(1-sin θ^ 2 )
sin θ^ 2 = ([A / l] ^ 2
so Vmax = √ (2GL (1 - √ (1 - ([A / l] ^ 2)))
university stage: you can first assume that the displacement function x = asin (WT)+ ψ), In the formula, a is the vibration amplitude. W = 2 Π / T, bring in the formula, select an initial phase, and you can calculate the displacement function. Find the first derivative of the displacement function, and remove the extremum. Then you can get the maximum speed.
it's depressing. The network display is incomplete. I wrote it in word. If you need it, leave an email and I can send it to you.
