Here is the link to the problem I am stuck on. I don't know what question b) means by solve for the boundary values? Are these the same as boundary conditions or are boundary values explicit values?

2. Relevant equations
NA

3. The attempt at a solution
How can I have an attempt if I have no clue how to start. Attempt = DNE

I think you are over-thinking this. The function f(x,y) = Cxy has specific values on each of the three boundary surfaces. What are these values? For example, what is the value of Cxy on the plane where y = 0?

Thanks phyzguy

Wouldn't it just be 0 when y=0?

Yes.

What about the xy plane? Would it be 0 to infinity?

Re-read the problem. The X-Y plane isn't one of the bounding surfaces.
