Set up but do not solve for the appropriate particular solution yp for the differential equation
using the Method of Undetermined Coefficients (primes indicate derivatives with respect to x).
In your answer, give undetermined coefficients as A, B, etc.
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]
