CSIN(3) Library Functions Manual CSIN(3)

csin, csinf, csinl — complex circular sine

#include <complex.h>

double complex
csin(double complex z);

float complex
csinf(float complex z);

long double complex
csinl(long double complex z);

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

If z = x + iy, then

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

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

ccos(3), ctan(3)

The csin(), csinf() and csinl() functions conform to ISO/IEC 9899:1999 (“ISO C99”).
