Method of undetermined coefficients problem

Click For Summary
SUMMARY

The discussion focuses on solving the differential equation 4y'' + 4y' + y = 3x e^x using the method of undetermined coefficients. The participants suggest that the assumed particular solution should take the form y = Ax e^x + Be^x. This approach aligns with the standard procedure for handling non-homogeneous linear differential equations with exponential functions.

PREREQUISITES
  • Understanding of differential equations, specifically second-order linear equations.
  • Familiarity with the method of undetermined coefficients.
  • Knowledge of exponential functions and their derivatives.
  • Basic algebraic manipulation skills.
NEXT STEPS
  • Study the method of undetermined coefficients in detail.
  • Practice solving various types of non-homogeneous differential equations.
  • Explore the characteristics of exponential functions in differential equations.
  • Learn about the general solution of second-order linear differential equations.
USEFUL FOR

Students and professionals in mathematics, engineering, and physics who are working with differential equations and seeking to enhance their problem-solving skills in this area.

I have the problem "Find the particular solution of 4y''+4y'+y=3xex.

What would be the assumed function y? Like would it be Ax ex?
 
Physics news on Phys.org
It would be more like Axe^x+Be^x.
 
ok, thanks, ill try that
