csinh(3) Library Functions Manual csinh(3)

csinh, csinhf, csinhl - complex hyperbolic sine

Math library (libm, -lm)

#include <complex.h>
double complex csinh(double complex z);
float complex csinhf(float complex z);
long double complex csinhl(long double complex z);

These functions calculate the complex hyperbolic sine of z.

The complex hyperbolic sine function is defined as:

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

These functions were added in glibc 2.1.

For an explanation of the terms used in this section, see attributes(7).
