11 double complex ccos(double complex z);
12 float complex ccosf(float complex z);
13 long double complex ccosl(long double complex z);

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
25 These functions first appeared in glibc in version 2.1.
