Evaluate (cosec θ – cot θ) (cosec θ – cot θ).(a) 0(b) 1(c) 2(d) 3I got this question in an online interview.My doubt stems from Trigonometric Identities topic in section Trigonometry of Mathematics – Class 10

Answer»

The correct CHOICE is (B) 1

The EXPLANATION: (cosec θ – cot θ) (cosec θ – cot θ) = cosec^2θ – cot^2θ

= 1

The identity used here is cosec^2θ – cot^2θ = 1
