Hi there,
In my course solid state physics, there is a part about the Lorentz oscillator. At a certain part, this is written:
"X(t) = X_0sin(-ωt+α)
This changes into:
X(t) = X_0 exp(-iωt)
by choosing X_0 as a complex number and putting the phase factor into the complex amplitude."
But I just don't see how you can do/prove this mathematically?
