In this problem, we'll rederive the Var of Par equations, but for
y" – 5y' + 6y = f(t)
Where f(t) is an inhomogeneous term
Recall that the homogeneous solution is yo = Ae²t +Be³t
Variation of Parameters: Suppose yp is of the form
Yp = u(t)e²t + v(t)e³t
And suppose for simplicity that
e²tu' (t) + e³¹ v′ (t) = 0
Calculate (yp)' and (yp)" and plug into the ODE to show
(2e²t) u'(t) + (3e³t) v'(t) = f(t)
