If ∫ f x log sin x d x = log [ log sin x ] + c , then f x =
Options
- Acot x
- Btan x
- Csec x
- Dcosec x
Correct answer
A. cot x
Step-by-step solution
Given ∫ f x log sin x d x = log [ log sin x ] + C By using anti differentiation method, we will get d d x log log sin x + c = 1 log sin x ⋅ 1 sin x ⋅ cos x = cot x log sin x ∴ f x = cot x
