/**
 * TankCircuit is a class with methods that can be used without initializing.
 *
 * Its methods provide calculations for a Tank Circuit (LC), (Inductor and Capacitor) resonant circuit.
 *
 * @example
 * const inductance  = 50 / 1000000000;
 * const capacitance = 50 / 1000000000000;
 * const frequency = TankCircuit.calcFrequency(inductance, capacitance);
 *
 * const frequency  = 100658424.20897408;
 * const capacitance = 50 / 1000000000000;
 * const inductance = TankCircuit.calcInductance(frequency, capacitance);
 *
 * const frequency  = 100658424.20897408;
 * const inductance  = 50 / 1000000000;
 * const capacitance = TankCircuit.calcCapacitance(frequency, inductance);
