It’s that time of the semester… related rates have returned in calculus. I have taught related rates problems in Calculus for years, but have never really been sure whether the students get the whole concept. There are now some excellent demos on the internet to help them see the problems in motion.
- Clock hands
- Radius, Surface Area, and Volume of a Sphere
- Boat being pulled into a dock
- Person walking away from a spotlight
So what’s missing? Would someone talented please do the inverted conical water tank problem or the searchlight problem as an animation? Or perhaps point me to where you’ve found them on the internet?
