Solve the following differential equations using method of
undetermined coefficients:
a) y''-5y'+6y=2t-3e^(-4t)
b)y''+4y=5cos(2x)
c)y''''-y''=3x+yxe^(-x)
d)y''-3y'-4y=3+e^(4t)
Again considering y'' + 4y' + 3y = 0:
(a) Solve the IVP y'' + 4y' + 3y = 0; y(0) = 1, y'(0) = α where
α > 0.
(b) Determine the coordinates (tm,ym) of the maximum point of
the solution as a function of α.
(c) Determine the behavior of tm and ym as α →∞.
