Second order non-homogeneous linear diff equations:
1. Find the general solution of the diff equations.
a. \(y''-3y'+2y=3e^t\) solution
b. \(y''-2y'=3e^{2t}\) solution
c. \( y''+4y=3\csc{t} \)
solution
d. \( y''+9y=2\sec^2{3t} \)
solution
2. Find the solution of the ODE by variation of parameters (do not use formula).
a. \(\displaystyle y''-2y'+y=t^{-1}e^t \) solution
b. \(\displaystyle y''-5y'+6y=2e^t \) solution
c. \(\displaystyle y''+16y=\sec(4t) \) solution
