Question

prove the identity picture is attached​

Answer 1

Answer:

LHS

(cosec+1)²/cot²

(cosec+1)²/(cosec²-1)                                            (identity: cosec²=1+cot²)

(cosec+1)²/(cosec+1)(cosec-1)                               (identity:(a²-b²)= (a+b)(a-b))

cosec+1/cosec-1= RHS

hence proved
