One receiver only measures a shadow of the wave. Sine and cosine together give the loudness: the length of the pointer, √(a² + b²).

A shifted station silences a sine radio. With two receivers, sine and cosine, loudness becomes the length of a pointer: √(a² + b²).

How a film works on heyprof

Every film here listens. Pause it, ask it questions and let it continue with your own examples.

  1. PauseTap pause or press the space bar. The film waits right at that moment.
  2. AskTap “Ask” and type what you want to know. The answer comes inside the film, with picture and voice.
  3. Steer itTell it what to show, for example “Do this with z = 2 − 3i”. The film sets up the app and works it out.
  4. Try it yourselfWhile it is paused, drag points and sliders yourself. “Continue” takes you back into the film.

Without an account: five questions per visit. With an account you can also ask by voice.
