2. Relevant equations

N/A

3. The attempt at a solution

I think the reason I can't solve this problem is possibly I failed to consider some important property of the laplace equation. I just don't have a club where to start. Here's my attempt:

"u" is clearly harmonic inside the unit ball. It seems to me that the relationship to be proved suggests a linear interpolation scheme can be used to determine any point inside the ball, which also suggests the divergent everywhere inside the ball is same??? I'm totally confused from here on.
