Best ResponseYou've already chosen the best response.0Yes it's just the answer has sine and cosines in it and I don't know how they got it

Best ResponseYou've already chosen the best response.1that's because your answer are complex conjugated solutions. Have you dealt with them before?

Best ResponseYou've already chosen the best response.1It's a bit hard to explain the nature of complex numbers and how they apply to Differential Equations in just one post, it's a rather big topic, but if you want, I can link you to Pauls Website where he deals with complex solutions.

Best ResponseYou've already chosen the best response.1just solve it using characterist equation; you should get expoential(like you always do) but with complex power; use euler idenity to get sin/cos
