SUMMARY

The discussion revolves around Sarah's confusion regarding solving a Partial Differential Equation (PDE) problem. She expresses difficulty in finding relevant examples and seeks guidance on how to approach the problem. Another participant suggests differentiating the function u(x,y) with respect to x and y, leading to a solution represented as A(u). However, Sarah questions the simplicity of this method, noting the lack of direct application of PDE concepts.

PREREQUISITES
  • Understanding of Partial Differential Equations (PDEs)
  • Knowledge of differentiation techniques in multivariable calculus
  • Familiarity with function notation, specifically u(x,y)
  • Basic problem-solving strategies in mathematical contexts
NEXT STEPS
  • Study the fundamentals of Partial Differential Equations (PDEs)
  • Learn advanced differentiation techniques for multivariable functions
  • Explore examples of PDE problem-solving strategies
  • Investigate the application of boundary conditions in PDEs
USEFUL FOR

Students and professionals in mathematics, particularly those studying or working with Partial Differential Equations, as well as educators seeking to enhance their teaching methods in calculus and differential equations.

hmmm i have no idea where to even start with this problem, i cannot find any examples that are similar or anything like that anywhere!

anyone got an idea as to a good first step to take?

thanks

sarah :)

edit: i tryed something wild and came up with http://img470.imageshack.us/img470/7415/picture22tm5.png but i didnt use any knowlage of PDE's to work that out...hmmm... :S

how did you get your answer??

i just differentiated u(x,y) with respect to x then respect to y and that gave me A(u)

but doesn't that seem to simple? i mean, there is no PDE stuff involved really... :S
