NAME
ctan, ctanf, ctanl - complex tangent function
LIBRARY
Math library (libm, -lm)
SYNOPSIS
#include <complex.h>
double complex ctan(double complex z); float complex ctanf(float 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)
