NAME
ctan, ctanf, ctanl - complex tangent function

LIBRARY
Math library (libm, -lm)

SYNOPSIS
#include <complex.h>

double complex ctan(double complex z);

long double complex ctanl(long double complex z);

DESCRIPTION
These functions calculate the complex tangent of z.

The complex tangent function is defined as:

    ctan(z) = csin(z) / ccos(z)
