I have a circuit that is two inductors and a capacitor in series, in the order inductor, capacitor, inductor, and I want to know what the resonance frequency of the system is (see image). I've heard before that, given the inductors are not coupled, it is just 1/2π√((L1+L2)*C), however, I am not sure if that only pertains to a circuit where the inductors are connected directly, such as in a Hartley oscillator.

Thanks for the help.

It pertains to any circuit where the inductors are in series AND where there is no coupling.
