I have a homework assignment that I am having trouble with for my circuit analysis class. It seems a lot of my troubles are stemming from not remembering how to solve some diff EQ's. Here is a link to my homework post where you can find ALL the information. I have just listed the equations I came up with here to cut down on the garbage. http://forum.allaboutcircuits.com/showthread.php?t=41608 Based on my (hopefully correct) work beforehand, I am left with three general solutions and I don't know how to solve for the coefficients. Gen. Sol. 1: I need to find A1 and A2. Gen. Sol. 2: I need to find B1 and B2 Gen. Sol. 3: I need to find K1 and K2 Thanks for any help in advance.
