#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.
