write all the trigonometric identities and prove that (1/ sec^2 theta - cos ^2 theta ( + )1/ cosec^2 theta - sin^2 theta) sin^2 theta. cos ^2 theta = 1 - sin^2 theta. cos^2 theta / 2+ sin^2 theta . cos^2 theta by using trigonometric identities

To Prove

..........................(1)

Let us use the relation secθ = 1/cosθ  and cosecθ = 1 / sinθ in LHS .

LHS becomes

..................(2)

Let us consider the following relations

.................(3)
.................(4)
............. (5)
By using relations (3), (4) and (5) in the right most part of relation-(2) , we rewrite relation (2) as
