solve using the method of undetermined coefficients
Homework Equations
v(t)=a*t*e^-t + be^-t + ct + d
The Attempt at a Solution
what i could do is that i replaced v(t) for x in the equation and got the following
Aa=-a
Ab=a-b-(1,0)
Ac=-(0,1)
Ad=c
now I am not sure how to continue from here i was told that vector a = (alpha, alpha)
to plug this in into the Ab equation so it ends up like this
(A+I)b=(alpha -1, alpha)
but that is giving me that 1 = 0 and I am stuck there
any help is appreciated
