NAME

6       ctan, ctanf, ctanl - complex tangent function
7

SYNOPSIS

9       #include <complex.h>
10
11       double complex ctan(double complex z);
12       float complex ctanf(float complex z);
13       long double complex ctanl(long double complex z);

DESCRIPTION

18       These functions calculate the complex tangent of z.
19
20       The complex tangent function is defined as:
21
22           ctan(z) = csin(z) / ccos(z)
23
