What are your initial/boundary conditions?

anonymous · Answer

There are two constants C1 and C2. First thing is you derive y twice and get first and second derivatives. So you will have two equations. Now solve these equations to eliminate C1 and C2

ganeshie8 · Answer

two constants  =>  you need to differentiate two times

anonymous · Answer

But how about the sine and cosine what I'm going to do with sine and cosine ?

ganeshie8 · Answer

number of constants is same as order of the DE right ?

anonymous · Answer

I think so :D :D

anonymous · Answer

@Kainui Actually the problem is to construct a differential equation. It's not about solving a differential eqn. So, boundary conditions are not needed.

kainui · Answer

Oh? I've never seen this type of problem before I'm sorry haha.

anonymous · Answer

That's ok Kainui :D/

anyone can help me ? :)

anonymous · Answer

@vanessaici  Post your first and second derivatives so that you can be assisted :)
