1, the Word document with MathType input formula, press and hold the "alt+\" key, you can convert the MathType formula into latex format. 2, the latex format formula code copied to word, before and after the "$" symbol, press "alt+\" key, the formula is switched to MathType format.For example: $-\sin \left (x \right) {

It was not until this game was stopped that it had no regrets. This is the most painful thing in the world. If God gives me another chance to play, I must pass the Customs!Description:If you really want to play this game, let's take a look at my questions first. I

Rotation formula of a plane point and a plane rotation formula Definition: the rotation of a point O above a plane is to make any pair of corresponding points P and P on the plane equal to the line segments connected to a fixed point O, that is, | OP | = | OP '|, And the directed angle Take the Cartesian coordinate system for the transformation formulaOrigin OCenter of rotation,Rotation Angle is BetaAny

First, do not be intimidated by the atan (x) formula! There are two ways to do this: 1. derivation formula: 1. Tan (a + B) = (TAN (A) + Tan (B)/(1-Tan (a) * Tan (B )) 2. Tan (atan (x) = x Arctan (1/S) = arctan (1/u) + arctan (1/V)So we get 1/S = tan (arctan (1/u) + arctan (1/V) = (TAN (arctan (1/U )) + Tan (arctan (1/V)/(1-Tan (arctan (1/U) * Tan (arctan (1/V ))) = (1/u + 1/V)/(1-1/(UV ))So UV = 1

HDU1001 for implicit type conversion of the accumulate formula, hdu1001 accumulate Formula HDU 1001 is stuck. Inspired by Xiao Bai, such cycle problems are directly converted into formulas for solving to optimize the time. But! I just can't go through it! Problem code: # Include The problem is that although the question indicates that the final result will be within 32 bits, there is no guarantee that
