Let’s see you generalize this to n-dimensions next.

Will do!

The generalization is quite technical so i will post the video in a few weeks after finals. In the meantime check out Evans PDE Section 2.4, the basic idea is to use spherical averages and a change of coordinates to reduce back to the dimension 1 equation.
