NAME

cacosh, cacoshf, cacoshl − complex arc hyperbolic cosine

SYNOPSIS

#include <complex.h>

double complex cacosh(double complex z);
float complex cacoshf(float complex
z);
long double complex cacoshl(long double complex
z);

Link with −lm.

DESCRIPTION

The cacosh() function calculates the complex acosh(). If y = cacosh(z), then z = ccosh(y). The imaginary part of y is chosen in the interval [−pi,pi]. The real part of y is chosen nonnegative.

One has cacosh(z) = (0.5)*clog((1+z)/(1−z)).
