#include <math.h> double sinh(double x);Description
sinh calculates the hyperbolic sine of x, with x expressed in radians.
sinh returns the value of the hyperbolic sine of x. If the result is too large, sinh sets errno to ERANGE and returns the value HUGE_VAL (positive or negative, depending on the value of x).
This example computes y as the hyperbolic sine of pi/2.
#include <math.h> int main(void) { double pi,x,y; pi = 3.1415926535; x = pi/2; y = sinh(x); printf("sinh( %lf ) = %lf\n", x, y); return 0; /**************************************************************************** The output should be: sinh( 1.570796 ) = 2.301299 ****************************************************************************/ }Related Information
