SUMMARY

The discussion focuses on solving second order inhomogeneous partial differential equations (PDEs), specifically the heat equation represented as ut = uxx + Sin(ax)Sin(bt). The user successfully applies separation of variables for the homogeneous case but seeks guidance on incorporating the forcing term Sin(x)Sin(t). The recommended approach involves using Green's function to address the inhomogeneous part of the equation, allowing for a systematic solution to the problem.

PREREQUISITES
  • Understanding of second order partial differential equations
  • Familiarity with the heat equation and its properties
  • Knowledge of separation of variables technique
  • Concept of Green's functions in solving PDEs
NEXT STEPS
  • Study the application of Green's functions for inhomogeneous PDEs
  • Explore the method of undetermined coefficients for forcing terms
  • Learn about Fourier series solutions for PDEs with periodic boundary conditions
  • Investigate numerical methods for solving inhomogeneous PDEs
USEFUL FOR

Students and researchers in applied mathematics, physicists dealing with heat transfer problems, and anyone looking to deepen their understanding of solving inhomogeneous PDEs.

Homework Statement


Hello, I'm having a problem solving second order inhomogeneous PDEs, for example the standard heat equation with a forcing term Sin(x)Sin(t) added onto it on the right hand side.


Homework Equations



ut = uxx + Sin(ax)Sin(bt)

The Attempt at a Solution


I can solve it for the homogeneous case using separation of variables, but where do I go from there? Thanks in advance.
