Sin cos exp is calculated using the Taylor Formula and mclawin formula. To prevent the power operation index from being too high, it is easy to cause overflow when a large input parameter is calculated. Considering that sin and cos both use 2 * PI

These are the formulas of the triangles.The triangle is a right angle of two sharp angles in short.Cos is the cosine theorem, which is the adjacent edge of the acute angle divided by the hypotenuse of the triangle.Sin is the sine theorem, which is

I've been trying to write an article for a long time and talk to you:\frac{1}{1^2}+\frac{1}{2^2} +\frac{1}{3^2} +\frac{1}{4^2} +\frac{1}{5^2} +\cdots\ =\ \frac{π^2}{6}But there has been no chance, this summer vacation just have free, so the hand

Feather painting by action Code: OnMouseDown = init; function init () {// create a feather, and set each feather parameter and call the function feather = createEmptyMovieClip ("f" + I, 10000 + I ++); feather. swapDepths (Math. random () * 10000);

High school time to do, the first two days to see, quite fun.Just want to say, the original code style,,, cough, not the coquettish!/***sin (x) and cos (x) images display simultaneously ***/# include # include int main  ( void )
