One of the most important and conceptual question from trigonometry, topic – trigonometric identities in which we have to find the value of sec²θ(1+sinθ)(1-sinθ) using trigonometric formulas
Kindly give me a detailed solution of this question
RS Aggarwal, Class 10, chapter 13C, question no 9
sec²θ(1+sinθ)(1-sinθ)
= sec²θ(1-sin²θ)
= sec²θ × cos²θ
= 1/cos²θ × cos²θ
= 1
