ધારો કે $I=\int_{-\frac{\pi}{4}}^{\frac{\pi}{4}} \frac{1}{2-\cos 2 x}\left(\frac{3}{\pi}+\log \left(\frac{4+\sin x}{4-\sin x}\right)\right) d x$. આપેલ છે કે $\int \frac{d x}{1+k x^2}=\frac{1}{\sqrt{k}} \tan ^{-1}(\sqrt{k} x)+c, \tan ^{-1}(0)=0$ અને $\tan ^{-1}(\sqrt{3})=\frac{\pi}{3}$. તો $3 I^2=$

  • A
    $4$
  • B
    $9$
  • C
    $16$
  • D
    $1$
