ધારો કે $I=\int \frac{e^x}{e^{4 x}+e^{2 x}+1} d x$ અને $J=\int \frac{e^{-x}}{e^{-4 x}+e^{-2 x}+1} d x$. તો,કોઈ સ્વૈચ્છિક અચળાંક $C$ માટે,$J-I$ નું મૂલ્ય શું થાય?

  • A
    $\frac{1}{2} \log \left(\frac{e^{4 x}-e^{2 x}+1}{e^{4 x}+e^{2 x}+1}\right)+C$
  • B
    $\frac{1}{2} \log \left(\frac{e^{2 x}+e^{x}+1}{e^{2 x}-e^{x}+1}\right)+C$
  • C
    $\frac{1}{2} \log \left(\frac{e^{2 x}-e^x+1}{e^{2 x}+e^x+1}\right)+C$
  • D
    $\frac{1}{2} \log \left(\frac{e^{4 x}+e^{2 x}+1}{e^{4 x}-e^{2 x}+1}\right)+C$
