| <p><a name="index-csin-188"></a><a name="index-csinf-189"></a><strong>Synopsis</strong> |
| <pre class="example"> #include <complex.h> |
| double complex csin(double complex <var>z</var>); |
| float complex csinf(float complex <var>z</var>); |
| |
| </pre> |
| <p><strong>Description</strong><br> |
| These functions compute the complex sine of <var>z</var>. |
