## The Attempt at a Solution

I found ω

_{0}= 1/√LC when I

_{R}is at its maximum. (Purely resistive)

I have a feeling that the last part requires an approximation and then an expansion which gives 2 values of ω.

But the thing is, (1 + x)

^{n}≈ 1 + nx + .....

only when x << 1

In this case it's L/RC << 1 which doesn't really fit..
