Complex Numbers up to Euler’s Formula

An explainer film in four chapters, made from a real lecture: why we need the number i, how to read complex numbers as points with length and angle, what happens when you add and multiply them, and how Euler’s formula explains multiplication. Pause anywhere and ask.
