    Using what I've learned in my ODE class, solving the 2nd order differential equation v'' + (1/RC)v' + (1/LC)v = 0 for this situation gives a different solution from my textbook's solution for some reason..

    But the book has v(t) = -14e^(-5000t) + 26e^(-20000t) though..

    L = 50mH, C = 0.2uF, and R = 200 Ohms as shown on the picture
