math.h, timath.h

void ctan (float z_re, float z_im, float *w_re, float *w_im);

Complex tangent.

ctan calculates the tangent w = tan(z) of the complex number which real and imaginary parts are z_re and z_im, and stores real and imaginary part of the result in floating point destinations pointed to by w_re and w_im. The complex tangent is defined by
tan(z) = sin(z) / cos(z)
where sin and cos are complex sine and complex cosine (see csin and ccos).
