SUMMARY

The discussion centers on understanding boundary values in the context of the function f(x,y) = Cxy. Participants clarify that boundary values refer to specific values on defined surfaces, not to be confused with boundary conditions. The value of Cxy on the plane where y = 0 is confirmed to be 0, while the xy plane is noted not to be one of the bounding surfaces. Engaging in dialogue helps participants gain clarity on the problem.

PREREQUISITES
  • Understanding of boundary value problems in mathematics
  • Familiarity with functions of two variables, specifically f(x,y) = Cxy
  • Knowledge of boundary conditions in differential equations
  • Basic algebraic manipulation skills
NEXT STEPS
  • Study boundary value problems in partial differential equations
  • Learn about boundary conditions and their applications in mathematical modeling
  • Explore the implications of functions defined on specific surfaces
  • Review examples of solving for boundary values in various mathematical contexts
USEFUL FOR

Students and educators in mathematics, particularly those studying boundary value problems and functions of multiple variables.

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?

Homework Equations


NA

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.
 
Ah yes I see now, I'm so dumb. Thanks so much! Always helps to talk about a problem.
