e^{iθ} = cosθ + i sinθ
It connects trigonometric and exponential functions.
e^{iθ} represents exponential increase with imaginary exponent.
e^{ix} = cos(x) + i sin(x) for any real x.
Taylor series for e^x, sin x, and cos x.
z = re^{iθ} for any complex number z.
It becomes addition: e^{iθ} * e^{iφ} = e^{i(θ+φ)}.
A point on the unit circle in the Argand plane.
(cos θ + i sin θ)^n = cos(nθ) + i sin(nθ).
It helps derive the theorem using (e^{iθ})^n.
