Enumerating selections from a 2xN grid with no horizontal or vertical adjacency.
A notebook for demonstrating how the critical point structure of a 1-parameter family of functions changes as you vary the parameter. You get an animation showing the graph of the function beside its contour map; the zero sets of the partials are color-coded, and critical points are identified, classified by the 2nd derivative test, and displayed both on the contour map and the graph of the function. Watch critical points appear, split, merge, and disappear as the parameter changes. I really like this one.
Level sets of a function of a function of two variables shown on the graph of the function and in a contour map simultaneously; step through the animation and watch the topology of the level sets change as you pass through critical heights.
