NAME

ctan, ctanf, ctanl - complex tangent function

LIBRARY

Math library (libm, -lm)

SYNOPSIS

bash

#include <complex.h>

bash

double complex ctan(double complex \nz\n);\n
\nfloat complex ctanf(float complex \nz\n);\n
\nlong double complex ctanl(long double complex \nz\n);

DESCRIPTION

These functions calculate the complex tangent of z.

The complex tangent function is defined as:

bash

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