NAME

csinh, csinhf, csinhl — complex hyperbolic sine

SYNOPSIS

#include <complex.h>

double complex
csinh(double complex z);

float complex
csinhf(float complex z);

long double complex
csinhl(long double complex z);

DESCRIPTION

The csinh(), csinhf() and csinhl() functions compute the complex hyperbolic sine of z.

For all complex floating-point numbers z,

csinh(z) = (cexp(z) - cexp(-z)) / 2.

RETURN VALUES

The csinh(), csinhf() and csinhl() functions return the complex hyperbolic sine of z.

SEE ALSO

ccosh(3), ctanh(3)

STANDARDS

The csinh(), csinhf() and csinhl() functions conform to ISO/IEC 9899:1999 (“ISO C99”).
