[QUOTE="Jbreezy, post: 4547737, member: 467277"] [h2]Homework Statement [/h2] Hi, I think this is called second order.So I'm working on a problem I haven't had lecture yet. I'm trying to understand. Oh wait here is problem. Someone can help me understand this sort of problem in general. For what values of k does the function y = coskt satisfy the diffy Q 4y'' = -25y? a.) For those values of k, verify that every member of the family of functions y = Asinkt + Bcoskt is also a solution. [h2]Homework Equations[/h2] [h2]The Attempt at a Solution[/h2] So, Here is all I know. Which isn't much. I'm used to just doing the first order? The ones that you just mess with then integrate and wahla. So how exactly do I do this and how do I generalize it. Because the book said every second order of ( they give a form) can be represented this way. Thanks, [/QUOTE]
