The equation for a driven damped oscillator is

(a) Explain the significance of each term.

(b) Let E = E₀e^iωt and x = x₀e^{i(ωt-α)}, where E₀ and x₀ are real quantities. Substitute into the above expression and show that 

(c) Derive an expression for the phase lag, α, and discuss how α varies as ω goes from ω << ω₀ to ω = ω₀ to ω >> ω₀.
