Example:
Output:
-2.000000 raised to 3.000000 is -8.000000
Calculates the trigonometric sine function of a double precision
floating-point value.
<math.h>
double sin (double x);
x
Returns the sine of x in radians in the ranges of -1 to 1 inclusive.
A domain error will occur if t x is a NaN or infinity.
#include <math.h>
#include <stdio.h> /* for printf, perror */
#include <errno.h> /* for errno
int main(void)
{
}
Output:
The sine of -1.000000 is -0.841471
The sine of 0.000000 is 0.000000
3.000000 raised to -0.500000 is 0.577350
Error: domain error
0.000000 raised to -3.000000 is inf
