Best ResponseYou've already chosen the best response.0do we use tan^2+1=sec^2 and 1+cot^2 =csc^2 for proving?

Best ResponseYou've already chosen the best response.1U can use any Identity for proving but here as far as I know only this will work...

Best ResponseYou've already chosen the best response.1there aren't any methods or anything..see u have 2 sides of a proof right..one side will be some complicated thing...while the other will probably be sumthin u know the direct equation for like here cos2x=cosxsinx...this u already know...so try converting the complicated thing in terms of the other side equation....
