NAME

ccos, ccosf, ccosl − complex cosine function

SYNOPSIS

#include <complex.h>

double complex ccos(double complex z);
float complex ccosf(float complex
z);
long double complex ccosl(long double complex
z);

Link with −lm.

DESCRIPTION

These functions calculate the complex cosine of z.

The complex cosine function is defined as:

ccos(z) = (exp(i * z) + exp(−i * z)) / 2
