Consider two statements $S_1$ and $S_2$.
$S_1$: If $f(x)$ is a differentiable function with $f'(x) > 0$ in $(a, b)$ and $f(x)$ is increasing in $(a, b)$,then $\frac{f(x)}{f'(x)}$ is also increasing in $(a, b)$.
$S_2$: Both $\sin x$ and $\tan x$ are increasing functions in $(0, \frac{\pi}{2})$.
Which of the following is true?

  • A
    Both $S_1$ and $S_2$ are wrong.
  • B
    $S_1$ is correct and implies $S_2$.
  • C
    $S_1$ is wrong and $S_2$ is right.
  • D
    Both $S_1$ and $S_2$ are right.
