Try determining the coefficients for 2' nonhomogeneous eq...
? How do you not know the coeffs but know it's 2nd order? Nevermind. It's not relevant.
That's the thing about the written word dude... You cain't see I'm full a sh!t all the time anyway... Note to self, when threatening bodily violence remember to put the ;)...

Yes it is. For example-- y"-3y'-4y = 3exp(2t) + 2sin(t) - 8exp(t)cos(2t)
