જો $y = \frac{1}{\sqrt{a^2 - b^2}} \cos^{-1} \left[ \frac{a \cos(x - \alpha) + b}{a + b \cos(x - \alpha)} \right]$ હોય,તો $\frac{dy}{dx} = $

  • A
    $\frac{1}{a + b \cos(x - \alpha)}$
  • B
    $\frac{2}{a + b \cos(x - \alpha)}$
  • C
    $\frac{1}{(a + b \cos(x - \alpha))^2}$
  • D
    $\frac{2}{(a + b \cos(x - \alpha))^2}$
