Calculate the sine of an angle
#include <math.h> double sin( double x ); float sinf( float x ); long double sinl( long double x );
These functions compute the sine of x radians. An argument with a large magnitude may yield a result with little or no significance.
The sine value. If x is +/-Inf, these functions return NaN.
#include <stdio.h> #include <math.h> #include <stdlib.h> int main( void ) { printf( "%f\n", sin(.5) ); return( EXIT_SUCCESS ); }
produces the output:
0.479426
