HELLO....
HERE IS UR ANSWER....
There are many tricks for solving Trigononmetry based problems. Below are a few tricks:
Use Componendo and Dividendo wherever necessary. Check the link below for Componendo and Dividendo.
When you get a huge expression to simplify/solve in this chapter, start off by grouping terms. Then, cancel out the common terms. Many problems are based on this trick.
Use the trigonometric identities in every problem that can be solved using them.
Apply the necessary form of each formula while solving problems.
Use transformations whenever you see an expression like: 2sinxcosy = 3 .
Square on both the sides whenever you see an expression where sine and cosine or tangent and secant or cotangent and cosecant are added and then solve.
Hope it helps u....
