CCOS(3)

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

VERSIONS
These functions first appeared in glibc in version 2.1.
