Thread: Need help with second-order ordinary differential equation

I am finishing up my year of Calc I/II BC. Our teacher is giving us some differential equations work. I don't understand it. Could I get some help with the attached problem.

Thanks,

Try the substitution where satisfies the original ODE and you'll get an ODE for (missing , just and ) so letting you'll get a linear first order ODE which you can solve.

That should get you started.
