How to use tanh() function to compute the hyperbolic tangent of N radians in C

Answer 1

#include <stdio.h>     
#include <math.h>

int main(int argc, char **argv)
{   
	printf("tanh(1) = %f\n", tanh(1));
    printf("tanh(-1) = %f\n", tanh(-1)); 
    printf("tanh(0.0) = %f\n", tanh(0.0));
    printf("tanh(-0.0) = %f\n", tanh(-0.0));
	printf("tanh(log(2.0)) = %f\n", tanh(log(2.0)));
	
    return 0;
}
 
/*
run:
   
tanh(1) = 0.761594
tanh(-1) = -0.761594
tanh(0.0) = 0.000000
tanh(-0.0) = -0.000000
tanh(log(2.0)) = 0.600000
