NAME

ctan, ctanf, ctanl - complex tangent function

LIBRARY

Math library (libm, -lm)

#include <complex.h>

double complex ctan(double complex z);
float complex ctanf(float complex z);
long double complex ctanl(long double complex z);

These functions calculate the complex tangent of z.

The complex tangent function is defined as:

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

For an explanation of the terms used in this section, see attributes(7).
