yeah i I did that but at the end of it I did not get the 2sin^2

At the end use property sin^2 + cos^2 = 1

at denominator

yeah that would give me 1/sin^2

Please check it

wait would my denominator be (sin^2+cos^2)/ sin^2?

similarly at denominatior , so sin^2 get cancel from both numerator & denominator ..

oh wow. so there would only be left cos^2 right

So what do you get ?

mari69755 Group TitleBest ResponseYou've already chosen the best response.0
at the top part do you multiply the a times y?

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

mari69755 Group TitleBest ResponseYou've already chosen the best response.0
yes so it would be sin^2cos^2+(sin^2cos^2) all divided by sin^2+cos^2?

mari69755 Group TitleBest ResponseYou've already chosen the best response.0
okay I understood it never mine. Thank you so much for your help. I did get 2sin^2 at the end.
