csin, csinf, csinl

Retrieves the sine of a complex number.

Syntax

_Dcomplex csin(
   _Dcomplex z
);
_Fcomplex csin(
   _Fcomplex z
);  // C++ only
_Lcomplex csin(
   _Lcomplex z
);  // C++ only
_Fcomplex csinf(
   _Fcomplex z
);
_Lcomplex csinl(
   _Lcomplex z
);

Parameters

z
A complex number that represents an angle, in radians.

Return value

The sine of z, in radians.

Remarks

Because C++ allows overloading, you can call overloads of csin that take and return _Fcomplex and _Lcomplex values. In a C program, csin always takes and returns a _Dcomplex value.

Requirements

Routine	C header	C++ header
