1. Find the general solution of the differential equation
.

It could be difficult right?
2. Why is no one helping me? 81 views and still no one.
Is it too hard?
3. Define s.t. , then note that:

,

Which reduces our non-linear ODE to the more reasonable second order ODE:

Then what you gonna do from there though?

You're asking the wrong question - the question is: what are you going to do from here? The ODE is not too difficult at all from this point; if you want more help, post your working.

If you're looking for a hint: Can you spot a substitution that simplifies this?

I've already got the answer doing it a different way - I don't need help. Seeing how others do it.
