Syntax
#include <math.h> double sin(double x);Description
sin calculates the sine of x, with x expressed in radians. If x is too large, a partial loss of significance in the result may occur.
sin returns the value of the sine of x.
This example computes y as the sine of pi/2.
#include <math.h> int main(void) { double pi,x,y; pi = 3.1415926535; x = pi/2; y = sin(x); printf("sin( %lf ) = %lf\n", x, y); return 0; /**************************************************************************** The output should be: sin( 1.570796 ) = 1.000000 ****************************************************************************/ }Related Information
