3.5.1.4.20 ImSin

Description

Calculate the sin value for a complex.

ImSin(C) = \frac{e^{iC}-e^{-iC}}{2i}

or

ImSin \left (x+iy \right ) = sin(x)cosh(y)+i*cos(x)sinh(y)

where C is complex, and i = \sqrt{-1}.

Syntax

complex ImSin(complex cX)

Parameters

cX

The complex number.

Return

Return the sin value for the specified complex.

Example

imSin(3+4i) = ;  // 3.8537380379194-27.016813258004i
 
complex c1 = 1+1i;
complex c2;
c2 = imSin(c1);
c2 = ;  // 1.298457581416+0.63496391478474i
