Question

please prove LHS equals to RHS or RHS equals LHS

PLEASE ​

Answer 1

Answer:

it is easy first convert LHS into sin value then remove cube and make sin²theta+cos²theta=1

Answer 2

we know the identity,

cosec²x=cot²x+1

by cubing both side we get,

(cosec²x)³=(cot²x+1)³

=(cot²x)³+1³+3cot²x(cot²x+1)

=(cot⁶x+3cot²x.cosec²+1)
