any tips to know which identity fit most?

Nikhil619Best ResponseYou've already chosen the best response.1
there 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....
