    Oh I get you. So you get better, and so you don't get tempted by the extra time you'll get from.

    .
    I substituted in x", x' and x into the original formula (or whatever they were) and it cancelled to get 0 = 0. so a can take any value at all, so there's no unique solution. is this enough proof?

    Well, what were you substituting in? (A+Bt)e^mt?

    Because that's still the if proof. You need to take the more generic y=u(t)e^mt, where u'' is not zero.

    I saw some guy earlier in the week selling them outside the Library (in the area between there, Ramphal and Social Sciences). And it was raining.

    ok.

    this is taking so long :sigh: what particular integral do I use for 3e^2t?
    Is this still the same question :holmes:

    no, but if I substitute (A+Bt)e^mt? into the equation, and u" is 0, it only leaves two terms instead of 3. I'm so confused :facepalm2:

    Ok, in the case (A+Bt)e^mt, u(t)=A+Bt

    ie u'=B and u''=0.

    So now you need to take a u(t) such that u'' is not zero.

    Say y=u(t)e^mt:

    Then y'=u'(t)e^mt+mu(t)e^mt
    and y''=u''(t)e^mt+mu'(t)e^mt+m^2u(t )e^mt+mu'(t)e^mt=u''(t)e^mt+2mu' (t)e^mt+m^2 u(t)e^mt=e^mt[u''(t)+2mu'(t)+m^2 u(t)]

    And probably sub that into the DE and see where it leads.
