NAME

6       ccos, ccosf, ccosl - complex cosine function
7

SYNOPSIS

9       #include <complex.h>
10
11       double complex ccos(double complex z);
12       float complex ccosf(float complex z);
13       long double complex ccosl(long double complex z);

DESCRIPTION

18       These functions calculate the complex cosine of z.
19
20       The complex cosine function is defined as:
21
22           ccos(z) = (exp(i * z) + exp(-i * z)) / 2
23

VERSIONS

25       These functions first appeared in glibc in version 2.1.
