Practical Electronics/Sin Wave Oscillator

With an LC series
 * $$L \frac{dI}{dt} + \frac{1}{C} \int I dt = 0$$
 * $$\frac{d^2I}{dt} + \frac{1}{LC} I = 0$$
 * $$\frac{d^2I}{dt} + \frac{1}{LC} = 0$$
 * $$\frac{d^2I}{dt} = -\frac{1}{T} $$
 * $$I = Ae^{\pm j \omega t} = A \sin \omega t$$

The reponse of an LC series is a Sinusoidal Wave or LC series can be used to produce Sin Wave Oscillator
