sin(), sinf() - sine function
#include <math.h>
double sin (double x)
float sin (float x)
The sin(3) and sinf(3) functions compute the sine of x (measured in radians). A large magnitude argument may yield a result with little or no significance.
The sin(3) and sinf(3) functions return the sine value.
