Hello, tttcomrader!
Of course, everything cancels out . . .Find the particular solution to:
I have .??
but for some reason when I plug in at the end everything cancels.
What was wrong?
To get in the solution, you need:
And is a solution to the homogeneous equation.
. . You need: .
Try it again with: .
You should get: .
Thank you so much, I was actually tutoring this course, and embarrassingly don't know how to do this.
Is there a proof for this on the internet? I really want to understand why I do these process. Thanks!
P.S. Why is one of the terms is , I didn't start with that term in the particular solution, and I didn't find that in the homogeneous solution.
Chris has a section on this here in MHF here is the link

The term comes from the original driving function and needs to be included in the particular solution.
