Sir please give me a detailed solution of this question as it is already asked in previous year paper of 2009 in which we have to find the value of cosec²θ(1+cosθ)(1-sinθ) using trigonometric formulas
RS Aggarwal, Class 10, chapter 13C, question no 10.
= cosec²θ (1-cos²θ)
= cosec²θ x sin²θ
= cosec²θ x 1/cosec²θ
