This is the basic and conceptual question from trigonometric identities in which we have to find the value of (cot²θ-1/sin²θ) using trigonometric formulas
Kindly give me a detailed solution of this question
RS Aggarwal, Class 10, chapter 13C, question no 6
Given cot²θ−1/sin²θ
=cot²θ−cosec²θ
we know
1+cot²θ=cosec²θ
⇒cot²θ−cosec²θ=−1
So,
cot²θ−1/sin²θ
=−1
