There is no specific method/ idea to prove a given trigonometric identity. Its just that you start with one side of the given statement and prove it equal to other side by using the three basic identities. Try to apply the identities wherever possible by using factorisation or rationalisation.
Also, once you practice proving more and more identities you will automatically get comfortable. As it is said "Practice makes a man perfect".
