ધારો કે $f(x) = \cos \left(2 \tan ^{-1} \sin \left(\cot ^{-1} \sqrt{\frac{1-x}{x}}\right)\right)$,$0 < x < 1$ માટે. તો :

  • A
    $(1-x)^{2} f^{\prime}(x)-2(f(x))^{2}=0$
  • B
    $(1+x)^{2} f^{\prime}(x)+2(f(x))^{2}=0$
  • C
    $(1-x)^{2} f^{\prime}(x)+2(f(x))^{2}=0$
  • D
    $(1+x)^{2} f^{\prime}(x)-2(f(x))^{2}=0$
