First of all you should learn all the trigonometric function be heart as well as identities.
Before you by heart Just understand how it came just understand derivation.
Second you should know the every possible conversion of one function into another .
Let sine can be written as tan×cos , cot×sin , or complex conversion like 1/(tan^2+1 )^1/2
and not just by byhearting but you should be able to to create /make conversion as required .
For proofs the best comments would be :
You should learn to make every such conversion then only you would able to solve trigonometry fast.
