Best ResponseYou've already chosen the best response.0yeah i I did that but at the end of it I did not get the 2sin^2

Best ResponseYou've already chosen the best response.0At the end use property sin^2 + cos^2 = 1

Best ResponseYou've already chosen the best response.0similarly at denominatior , so sin^2 get cancel from both numerator & denominator ..

Best ResponseYou've already chosen the best response.0oh wow. so there would only be left cos^2 right

Best ResponseYou've already chosen the best response.0at the top part do you multiply the a times y?

Best ResponseYou've already chosen the best response.0in our step x = (sin^2  cos^ ) & y = sin^2 + cos^2 & a = 1

Best ResponseYou've already chosen the best response.0yes so it would be sin^2cos^2+(sin^2cos^2) all divided by sin^2+cos^2?

Best ResponseYou've already chosen the best response.0okay I understood it never mine. Thank you so much for your help. I did get 2sin^2 at the end.
