But a sinusoidal oscillation turns out to be a particularly useful one. If we oscillate our hand up and down like a simple (undamped) harmonic oscillator, (1) y ( 0, t) = A sin ω t.

First, a sinusoid is just an exponential in disguise: sin θ = eiθ −e−iθ 2i. cos θ = eiθ +e−iθ 2. Second, the exponentials are eigenfunctions of the derivative and integral operators. That means if you put an exponential function in to a derivative, you get a complex exponential out.Web
