Multiple inductor or capacitor RLC circuits

[ricc]

So I know that the equation for the natural frequency of an RLC circuit is:
ω₀=(LC)^-1/2
I'm just wondering how this would change for a circuit with more than one inductor or capacitor. Say for instance an inductor in parallel with a capacitor, both connected in series to another inductor.

Cheers in advance for any help you can give me.

It is easy to write down an equation and even analyze it, once a circuit diagram exists. Specifically, the ac impedances of resistors, inductors, and capacitors are R. jωL, and 1/(jωC).
