Trying to write

[tex]

-8\pi - 8\pi\sqrt3 j

[/tex]

in exponential

I got the coefficient as 16 pi

but to get the theta in top of the exponential I have to do

the inverse tangent of [tex]

\frac{-8\pi} {-8\pi\sqrt3 j}

[/tex]

I know it is pi over 3, but what is the easiest way to find the multiplicative factor of pi? it is four I just want to know how to find it for other harder examples

answer [tex]

16e^{\frac{j4\pi} 3}

[/tex]

Input appreciated
