Question

prove that sec^2theta.cosec^2theta - tan^2theta - cot^2theta - 2 = 0​

Answer 1

Answer:

Question:➡️

prove that :➡️sec²θ + cosec²θ − tan²θ − cot²θ = 0

Solution :➡️

basic information :➡️

☞ 1 + tan²θ ➡️sec²θ

☞ 1 + cot²θ ➡️ cosec²θ

therefore

LHS

1 + tan²θ + 1 + cot²θ - tan²θ - cot²θ

☞ 2

also,

RHS = 2

LHS = RHS

hence proved .

hope it helps you ✌️✌️
