NAME

       csin, csinf, csinl - complex sine function

LIBRARY

       Math library (libm, -lm)

SYNOPSIS

       #include <complex.h>

       double complex csin(double complex z);
       float complex csinf(float complex z);
       long double complex csinl(long double complex z);

DESCRIPTION

       These functions calculate the complex sine of z.

       The complex sine function is defined as:

           csin(z) = (exp(i * z) - exp(-i * z)) / (2 * i)
