Test III has been prepared. Here are a few observations concerning the test.

There are 10 problems each from Chapters 9 and 10. The last is extra credit. Of those from Ch 9, you'll see at least one each of the three conic types.

There may be problems where you are asked to match an equation to one of four graphs (or "None of the above").

Since you'll be given the standard forms of the conic equations, you can focus on the particular details of each (vertex, focus, etc.).

Look at the problem and provide the best answer to that problem.

When all the testing is over, you might find it interesting to peruse Rasko Jovanovic's "FIBONACCI NUMBERS and PASCAL TRIANGLE" site. Start, perhaps, with "Triangular numbers." Work up to "Tetrahedral numbers." How about "Pentatope numbers?" This is my reference for the 'partial sums of tallies' idea. One thing I like is the notion that negative n, t, and T numbers can be defined as "series complements" of partial sums. If you think you've seen everything, ponder these ideas. (I noticed a couple of typos in Rasko Jovanovic's exposition, but the idea seems sound.)
