How to use sinh() function to get the hyperbolic sine of an angle of N radians in C

Answer 1

#include <stdio.h>     
#include <math.h>
 
#define PI 3.14159265
 
int main(int argc, char **argv)
{   
	printf("sinh(PI / 6) = %f\n", sinh(PI / 6));
    printf("sinh(PI / 2) = %f\n", sinh(PI / 2));
	printf("sinh(PI / 180) = %f\n", sinh(PI / 180));
    printf("sinh(-2 * PI / 4) = %f\n", sinh(-2 * PI / 4));
    printf("sinh(+0) = %f\n", sinh(0.0));
    printf("sinh(-0) = %f\n", sinh(-0.0));
    printf("sinh(+1) = %f\n", sinh(1.0));
    printf("sinh(-1) = %f\n", sinh(-1.0));
    printf("sinh(log(2.0)) = %f\n", sinh(log(2.0)));
  
    return 0;
}
 
/*
