Best ResponseYou've already chosen the best response.1Try this. First, change all tan(x) and cot(x) into sin(x)/cos(x) and cos(x)/sin(x) respectively. Then combine the fractions using common denominator which is cos(x)sin(x). Hba.

Best ResponseYou've already chosen the best response.1No if you try to reduce it,It will come to \[ \sin^2x \cos^2x \]

Best ResponseYou've already chosen the best response.0Agreed. I see you now. I have it on my paper. But now you have your +2cos^2 on there. I know sin+cos=1 (as long as they are both squared)...but what about the rest?

Best ResponseYou've already chosen the best response.1Then put it in the actual ques. \[\sin^2x \cos^2x + 2\cos^2x = 1\]
