Shortest distance between lines:

\frac{x-1}{2}=\frac{2 y-2}{3}=\frac{z-3}{1}

and

\frac{x-2}{3}=\frac{y-1}{2}=\frac{z+2}{4}

View answer and explanation

Correct option: A

\frac{13}{\sqrt{165}}

Option A (

1+\frac{e^2}{4}

) is correct because it satisfies the given differential equation and initial condition when solving for y(e).
