MCQ
On the interval $\left( {0,{\pi \over 2}} \right)$, the function $ log \,sin \,x $ is
  • Increasing
  • B
    Decreasing
  • C
    Neither increasing nor decreasing
  • D
    None of these

Answer

Correct option: A.
Increasing
a
(a) Let $f(x) = \log \sin x \Rightarrow f'(x) = \cot x$

Hence function is increasing on the interval $\left( {0,\frac{\pi }{2}} \right)$.
