NAME

csin, csinf, csinl — complex circular sine

SYNOPSIS

/* -lm */
#include <complex.h>

double complex
csin(double complex z);

float complex
csinf(float complex z);

long double complex
csinl(long double complex z);

DESCRIPTION

The csin(), csinf() and csinl() functions compute the complex circular sine of z.

If z = x + iy, then

csin(z) = sin(x) cosh(y) + i cos(x) sinh(y).

RETURN VALUES

The csin(), csinf() and csinl() functions return the complex circular sine of z.
