請以分解降階法求1~4題之特解
1. y" – 5 y' +6y = e4x
2. y" – 5y' +6y = e2x
13. y" - 2 y' + y = x – 2
4. y" + 2y' + 5y = e 2x
請以分解降階法求 5~7 題之確解。
5 y" – 4y' = e*
6. y" + 7y' +12y = e-3x
7. (D+1)(D-2)(D+3)y = el
請以待定係數法求8~12 題之特解。
18. y" - 5y' +6y=es
9. (D+1)(D-2) y = net
10. y" - 2 y' + y = x - 2
1. y" - 5y' +6y=cos 3x
