About this app

Related Rates is an interactive calculus practice app that shows how connected quantities change together. Explore a sliding ladder, an expanding balloon, and a filling cone-shaped tank while adjusting a measurement and observing the resulting rate of change. Guided missions help learners connect geometric equations with derivatives such as dx/dt, dy/dt, dV/dt, and dh/dt.

Use cases

  • High school students practicing related-rates problems
  • Teachers demonstrating derivatives with visual examples
  • Learners exploring how geometry affects changing rates
  • Math classes reviewing ladder, sphere, and cone models

Features

  • Three interactive scenarios: ladder, balloon, and cone tank
  • Step controls for changing distance, radius, or water height
  • Displays calculated related rates and linked quantities
  • Balloon mode can hold dr/dt or dV/dt fixed
  • Guided missions with reset, next, and completion feedback
