यदि $0 < a < 1$ है,तो $\int \frac{dx}{1-2a \cos x + a^2} =$

  • A
    $\frac{1}{1-a^2} \tan^{-1}\left[\frac{1+a}{1-a} \tan \frac{x}{2}\right] + c$
  • B
    $\frac{2}{1+a^2} \tan^{-1}\left[\frac{1-a}{1+a} \tan \frac{x}{2}\right] + c$
  • C
    $\frac{2}{1-a^2} \tan^{-1}\left[\frac{1+a}{1-a} \tan \frac{x}{2}\right] + c$
  • D
    $\frac{2}{1+a} \tan^{-1}\left[\frac{1-a^2}{1+a^2} \tan \frac{x}{2}\right] + c$
