This one is essentially the same problem as the #1 circuit thread I made...
For some reason though it looks like she solved it differently.

Again what I don't understand is the circled part
The asterisk I put because I see that since i = Cdv/dt then just differentiating that V = A1e^s1t + A2e^s2t term you get the i equation... Where did she pull that V equation that I circled from?
Is it easier to setup the differential equation for one variable instead of the other? i.e. in the RLC #1 circuit thread she sets it up in terms of i, in this one in terms of v...
