y=y(x)

is the solution of the differential equation

\left(1+e^{2 x}\right) \frac{d y}{d x}+2\left(1+y^2\right) e^x=0

and

y(0)=0

then which of the following is correct

View answer and explanation

Correct option: A

2 \tan ^{-1}\left(e^x\right)+\tan ^{-1} y=\frac{\pi}{2}

Option A,

2 \tan ^{-1}\left(e^x\right)+\tan ^{-1} y=\frac{\pi}{2}

, is the correct solution obtained by separating variables, integrating, and applying the initial condition.
