Weird ODE containing cos.
1. The problem statement, all variables and given/known data
I can not determine the solution to the diff. eq.
2. Relevant equations
The constant k is postive.
3. The attempt at a solution
I tried solving it with the methods I know and it all ended up in a big mess. I am just not used to the second term, \cos. Doe's anyone know what to do?

It's GOT to be something of the form
[tex]x=arccos(y)[/tex] for some y a function of t, based on an argument of 'this is really fricking hard otherwise'. Try the substitution and see what you get

I am not sure that is going to be easy to integrate, but that gives the solution.
