csin, csinf, csinl - complex sine function
#include <complex.h> double complex csin(double complex z); float complex csinf(float complex z); long double complex csinl(long double complex z); Link with -lm.
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)
These functions first appeared in glibc in version 2.1.
