Can someone please explain how to get to the above conclusion for T from the equation provided? I understand:
$e^{iwT} = 1$
Can be written as:
$\cos(wT) + i\sin(wT) = 1$
But I’m at a loss as how to proceed further. Though I know:
$T = \frac{2\pi}{w} $
It’s been a while since I’ve done this kind of math so if there’s a resource anyone can recommend for a refresh I’m open to suggestions. Also if there are better tags for this feel free to let me know.
