NAME

6       ctan, ctanf, ctanl - complex tangent function
7

LIBRARY

9       Math library (libm, -lm)
10

SYNOPSIS

12       #include <complex.h>
13
14       double complex ctan(double complex z);
15       float complex ctanf(float complex z);
16       long double complex ctanl(long double complex z);
17

DESCRIPTION

19       These functions calculate the complex tangent of z.
20
21       The complex tangent function is defined as:
22
23           ctan(z) = csin(z) / ccos(z)
