Here, I am writing theta as A.
LHS:
Given tan^2A + cot^2A + 2 .
= > tan^2A + cot^2A + 1 + 1
= > (tan^2A + 1) + (cot^2A + 1)
= > sec^2A + cosec^2A
= > (1/cos^2A) + (1/sin^2A)
= > (sin^2A + cos^2A)/(sin^2A * cos^2A)
= > 1/(sin^2A * cos^2A)
= > (1/sin^2A) * (1/cos^2A)
= > cosec^2A * sec^2A.
= > RHS.
Hope this helps!
