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.
