 Author Comment/Response Lauren 10/11/05 4:57pm I put into mathmatica DSolve[{y''[t] - 2y'[t] - 3y[t] == 3t(\[ExponentialE](2t))}, y[t], t] the result is \!\({{y[t] -> \(-\(2\/9\)\)\ \((14\ \[ExponentialE] - 12\ \[ExponentialE]\ t + 9\ \[ExponentialE]\ t\^2)\) + \ \[ExponentialE]\^\(-t\)\ C[1] + \[ExponentialE]\^\(3\ t\)\ C[2]}}\) So basically the problem is it says part of the answer is 14Exp + ..., but it is the exponent of nothing, this answer makes no sense, what is wrong?
