Question

How to use cosh() function to get the hyperbolic cosine of N radians in C

Answer 1

#include <stdio.h>     
#include <math.h>
 
int main(int argc, char **argv)
{
	printf("cosh(-1) = %.6f\n", cosh(-1));
    printf("cosh(1) = %.6f\n", cosh(1));
    printf("cosh(0) = %.6f\n", cosh(0));
	printf("cosh(-0) = %.6f\n", cosh(-0));
    printf("cosh(0.9) = %.6f\n", cosh(0.9));
    printf("cosh(3.141593 / 3) = %.6f\n", cosh(3.141593 / 3));
    printf("cosh(3.141593 / 2) = %.6f\n", cosh(3.141593 / 2));

    return 0;
}

/*
run:
  
cosh(-1) = 1.543081
cosh(1) = 1.543081
cosh(0) = 1.000000
cosh(-0) = 1.000000
cosh(0.9) = 1.433086
cosh(3.141593 / 3) = 1.600287
cosh(3.141593 / 2) = 2.509179
