Coffee, Crime, Circle: What Is a Differential Equation?

Prof. Dr. Dirk Schieborn

Higher Mathematics 2 · Reutlingen University

A differential equation looks for a function of which you only know its derivative. Whether a suspect is the culprit is always decided by the check.

Coffee, Crime, Circle: What Is a Differential Equation?

Prof. Dr. Dirk SchiebornHigher Mathematics 2 · Reutlingen University

NewOct 26, 2026 · 5 chapters

An explainer film in five chapters, made from a real lecture: why the culprit in a differential equation is a function, where differential equations hide, from cooling coffee to hares and foxes, how to solve y′ = 5y by guessing and checking, why the whole family C · e⁵ˣ belongs to it, and why only circles fit y′ · y = −x. Pause anywhere and ask.

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.
