I. Solve the homogeneous differential equations with the
constant coefficient.
a. ? ′′ + 5? ′ + 6? = 0
b. 4? ′′ − 8? ′ + 3? = 0 ? (0) = 2, ? ′ (0) = ½
II. Solve non-homogeneous differential equations with the indeterminate coefficient method.
a. ?′′ − 3? ′ = 5cos(?)
b. ? ′ ′ + 5? ′ + 2? ′ = 7? 3?
III. Solve non-homogeneous differential equations with the
parameter variation method.
