In Problems 1-8, decide whether or not the method of unde-
termined coefficients can be applied to find a particular solu-
tion of the given equation.
1. y" + 2y'-y = t¹¹e¹
2. 5y"-3y' + 2y = t³ cos 4t
3. 2y" (x) -6y'(x) + y(x) = (sinx)/e4x
4.
x" + 5x' - 3x = 3¹
5.
y" (0) + 3y' (0) − y(0) = sec 0
6. 2w" (x) - 3w(x) = 4x sin²x + 4x cos²x
7. 8z'(x) — 2z(x) = 3x¹00e4x cos 25x
8. ty" - y' + 2y = sin 3t
In Problems 9-26, find a particular solution to the differential
equation.
9. y" + 3y = -9
11. v"(x) +v(x)
