Best ResponseYou've already chosen the best response.1it's \[\cot(\frac{5}{4}\pi) = \frac{\cos(\frac{5}{4}\pi)}{\sin(\frac{5}{4}\pi)}\] can you find those?

Best ResponseYou've already chosen the best response.1yeah I figured that, my point was that \[\cos(\frac{5}{4}\pi)=\cos(\frac{5}{4}\pi)=\frac{1}{\sqrt{2}}\] and \[\sin(\frac{5}{4}\pi)=\frac{1}{\sqrt{2}}\]
