NAME
     ccos, ccosf, csin, csinf ctan, ctanf -- complex trigonometric functions

LIBRARY
     Math Library (libm, -lm)

SYNOPSIS
     #include <complex.h>

     double complex
     ccos(double complex z);

     float complex
     ccosf(float complex z);

     double complex
     csin(double complex z);

     float complex
     csinf(float complex z);

     double complex
     ctan(double complex z);

     float complex
     ctanf(float complex z);

DESCRIPTION
     The ccos(), csin(), and ctan() functions compute the cosine, sine, and tangent of the complex number z, respectively.  The ccosf(), csinf(),
     and ctanf() functions perform the same operations in float precision.
