Diving into Rates of Change

Image by John O'NolanEvery holiday season, there's one toy every child yearns for, the hot toy of the year that's in short supply but high demand. In ages past, Cabbage Patch Kids, Furbies, and Tickle Me Elmos topped the sales charts, but not this year. No sir (or madam, as the case may be).

In the new Problem of the Week, we announce this year's must have toy: My First Cliff Diving Kit! You'll be the talk of the town as you plummet from astronomical heights, narrowly dodging razor-sharp rocks, and land in water less than four feet deep. The only thing you'll be tickling is your fancy (or the side of the hospital bed in a desperate request for additional painkillers because you forgot to calculate for wind on your most recent dive).
