Question

2+1/tan^2A + 1/cot^2A= sec^2A+cosec^2A
With full explanation​

Answer 1

Answer:

Step-by-step explanation:

LHS = 2 + 1/tan^2 A + 1/cot^2 A

       = 1 + 1 + cot^2 A + tan^2 A

       = sec^2 A - tan^2 A + tan^2 A + cosec^2 A - cot^2 A + cot^2 A

       = sec^2 A + cosec^2 A

       = RHS
