Question

cosec a /cosec a -1 +cosec a/cosec a+1 =2sec square Ais

Answer 1

Ur answer is....




Hope it helps

Answer 2

Answer:

LHS = cosecA (cosecA+1)+cosecA(cosecA-1)  /  cosec^2A -1

       =  cosecA (cosecA+1+cosecA-1)  / cot^2A

       = 2cosec^2A  / cot^2A

       = 2 / sin^2A / cos^2A / sin^2A

       = 2 / cos^2

       = 2sec^2A

RHS = 2sec^2A

                        LHS=RHS
