David R. Hill (of Demos with Positive Impact) was nice enough to create demos for the three problems I requested on a previous post.

The Cylinder Problem

The Beacon Following a Person Problem

The Inverted Cylindrical Tank Problem

All of these demos, and more, can be found in the Related Rates Gallery at the Demos with Positive Impact site.

Now that we know David’s reading… does anyone have any other suggestions for problems that need demos?
