csinh(3) Library Functions Manual csinh(3)

NAME top

   csinh, csinhf, csinhl - complex hyperbolic sine

LIBRARY top

   Math library (_libm_, _-lm_)

SYNOPSIS top

   **#include <complex.h>**

   **double complex csinh(double complex** _z_**);**
   **float complex csinhf(float complex** _z_**);**
   **long double complex csinhl(long double complex** _z_**);**

DESCRIPTION top

   These functions calculate the complex hyperbolic sine of _z_.

   The complex hyperbolic sine function is defined as:

       csinh(z) = (exp(z)-exp(-z))/2
