csin(), csinf(), csinl()

Compute the complex sine

Synopsis:

#include <complex.h>

double complex csin( double complex z );

float complex csinf( float complex z );

long double complex csinl( long double complex z );

Arguments:

z
The complex value that you want to get the complex sine of.

Library:

libm

Use the -l m option to qcc to link against this library.

Description:

These functions compute the complex sine of z. The sine is an entire function on the complex plane, and has no branch cuts.

Returns:

The complex sine of z. Errors and special cases are handled as if the operation were implemented as -i * csinh(i * z).
