Best ResponseYou've already chosen the best response.2given \[x+y=90\] \[\frac{\sin x \tan y}{\sin y \tan x}\ \ \ \ \ \ \ =\] write all in terms of y=90x @eroshea what's sin (90x)??

Best ResponseYou've already chosen the best response.2good, so sin y=sin (90x)=cos x similarly change tan y in terms of x

Best ResponseYou've already chosen the best response.2good so \[\frac{\sin x \tan y}{\sin y \tan x}\ \ \ \ \ \ \ =\frac{\sin x \cot x}{\cos x \tan x}\ \ \ \ \ \ \ = ?\] Can you simplify this now?
