Question regarding P3 on TT

(1/1)

kevin:
for some problem 3 we choose y1 = Ae^t and sometimes we choose y1 = Bte^t (just like the question below) How do we know when to choose which term for y1?

YuyingC:
When we choose y1=Ae^t and the result is 0 regardless of A, then we need to choose y1=Ate^t.

Yuanting Wu:
The letters are used to help you find the particular solution. The reason why different letters are used is to avoid duplication.
