Summary: MATH 336 Extra review questions for Exam 2
Prof. Ammar
1. Determine the general solution of each of the following differential equations.
(a) y(3)
+ 6y + 9y = 0
(b) y + 2y + 5y = 0
(c) y(4)
- 81y = 0
(d) y(4)
- 2y(3)
+ 5y = 0
2. Using the method of undetermined coefficients, find the solution of the initial-value problem
y - 4y - 5y = 4e3x
; y(0) = 2, y (0) = 8
3. Determine the form of a particular solution of the following differential equation. (Do not
solve for the unknown coefficients.)
y(3)
- y = 1 + e-x
+ xex
.
