Question Detail
Question
Evaluate (cosec θ - cot θ)(cosec θ + cot θ).
Correct Answer
Option B is the correct answer.
Detailed Explanation
(cosec θ - cot θ)(cosec θ + cot θ) = cosec²θ - cot²θ. Using the identity cosec²θ = 1 + cot²θ, we get cosec²θ - cot²θ = 1.
Hint
Use the difference of squares formula and trigonometric identities.
