I was struggling to represent the following for integer values of n:
[tex]
\sin \left( \dfrac {n\pi } {2}\right)
[/tex]
I know for even n, we get zero
But for odd n, it alternates beween 1 and -1 for every other odd. Is there a compact way to represent that? I feel like I'm being dumb and missing something obvious.
Thanks!
