The discussion revolves around a problem related to boundary values in a mathematical context, specifically involving a function defined on certain surfaces. The original poster expresses confusion regarding the terminology of "boundary values" and how they relate to boundary conditions.
Participants are actively engaging with the problem, with some providing guidance on identifying values of the function at specific boundaries. There is a recognition of misunderstanding regarding the boundaries involved, and clarification is being sought.
There is mention of specific planes and surfaces that are relevant to the problem, with some participants correcting assumptions about which surfaces are considered boundaries. The original poster expresses a sense of confusion and seeks reassurance through discussion.
phyzguy said: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?
Yes.Teachme said:Thanks phyzguy
Wouldn't it just be 0 when y=0?
What about the xy plane? Would it be 0 to infinity?phyzguy said:Yes.
Ah yes I see now, I'm so dumb. Thanks so much! Always helps to talk about a problem.phyzguy said:Re-read the problem. The X-Y plane isn't one of the bounding surfaces.
