## Homework Statement

r" = 1/r^2

## Homework Equations

A friend gave this to me, he was just wondering how we'd approach it.

## The Attempt at a Solution

I don't think the equation is linear, so I don't know how to approach it. My friend suggested integrating both sides with respect to r, but we don't know if that's legal because we don't know what r might be a function of.
