ctan, ctanf, ctanl - complex tangent function
#include <complex.h>
double complex ctan(double complex z);
float complex ctanf(float complex z);
long double complex ctanl(long double complex z);
Link with -lm.
These functions calculate the complex tangent of z.
The complex tangent function is defined as:
ctan(z) = csin(z) / ccos(z)
These functions first appeared in glibc in version 2.1.
For an explanation of the terms used in this section, see attributes(7).
