From Climb Rate to Height

An explainer film in four chapters: from a drone’s climb rate back to its height — via strips, area and antiderivative to the fundamental theorem. Pause anywhere and ask.

A film you can ask questions.

• Pause wherever you like — click the picture or press the space bar.
• Pick one of the prepared questions about this very moment or ask your own. Without an account you get five questions per visit.
• The answer comes inside the film: with voice, subtitles and the app as the stage. Then the film continues where you left off.
• Every chapter runs in a real heyprof app. “Try the app yourself” lets you use it hands-on.
