Title: Section 4.3 Question5
Post by: Jiayi Wang (Ivy) on November 03, 2020, 04:32:16 PM
For this question, I got the homogeneous solution: y(t)=c1+tc2+e^(2t)c3+e^(-2t)c4 ;
Then I set the particular solution as Yp(t)=t^2(at^2+bt+c)+de^t;
I am not sure the part t^2(at^2+bt+c) is correct or not. Can someone please help? Thanks!
