Find a series expansion for a harmonic function on the solid square

[mathhead]

Number 3 is very difficult for me because we are finding the series expansion of a square.

"Number 3 is very difficult for me because we are finding the series expansion of a square."

You have a square [L x L] and you are given boundary condition.

Forget the word "square" (if that is confusing you) - Just solve the PDE with the given boundary conditions.

Now I get it. I was looking at your threads wondering, "What is mathhead doing?"

You're posting the word "edited" to denote that you've made changes to some original posts, yes?

May be better to type more than one word, to help denser people (like me).

EG: "I just edited my original post."
