Then if want to prove two equation : one has cos sin and on other side there is tan sec cot or cosec , then change all the terms in tan cot expression to sin and cos sometimes this gives you answer directly .

Sometimes you may have to rationalize or use algebraic identities such as (a^2 - b^2) or something like that.
