NAME

casinh, casinhf, casinhl - complex arc sine hyperbolic

LIBRARY

Math library ( libm , -lm )

SYNOPSIS

#include <complex.h>

double complex casinh(double complex z );
float complex casinhf(float complex
z );
long double complex casinhl(long double complex
z );

DESCRIPTION

These functions calculate the complex arc hyperbolic sine of z . If y = casinh(z) , then z = csinh(y) . The imaginary part of y is chosen in the interval [-pi/2,pi/2].

One has:

casinh(z) = clog(z + csqrt(z * z + 1))
