taking (sin A /cotA-cosec A) to the lhs
(sin A /cot A+ cosec A)-(sin A /cotA-cosec A) =2

take LCM,you get
-2 cosecAsinA/-1 =2 (since cot2A-cosec2A)

But, can we actually take it to the LHS?
Is there a way to solve this question without taking it to the LHS?

shine ali, sorry i am too late.
i did not notice your question.
yet there is another possible method,
take LCM on both sides you will get LHS=RHS=1-costheta
