(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Set up but do not solve for the appropriate particular solution yp for the differential equation

y''+25y=–1xcos(5x)

using the Method of Undetermined Coefficients (primes indicate derivatives with respect to x).

In your answer, give undetermined coefficients as A, B, etc.

2. Relevant equations

Possible Derivatives

- sin(x)
- cos(x)
- xsin(x)
- xcos(x)

3. The attempt at a solution

This seems like the solution should simply be

[tex] A*x*sin(5*x)+B*x*cos(5*x)+C*cos(5*x)+D*sin(5*x) [/tex]
