MATH WORKSHOP 8
November 13, 2007
Work on this workshop in groups of 3 or 4, constituted as you like.
We only have one hour for this workshop, so please stay focused.
I: GOING OVER THE HOMEWORK
II: NON-EUCLIDEAN GEOMETRY
1. Do Excursion Exercises 1-6 from the Excursion on pages 542-544 of ME. Come get the necessary materials from one of the grownups.
III: EUCLIDEAN GEOMETRY
2. As a group, try to find a proof of the Pythagorean Theorem. (Hint: focus on drawing useful diagrams.) If that doesn’t pan out, come get some diagrams from Brian/Steven/Taiyo that suggest proofs of the Pythagorean Theorem; work with your group to understand the arguments suggested by those diagrams. Write down at least one of those proofs in your own words, presumably with accompanying diagram.
IV: EXAM PREP
There’s no time for this in workshop today, but of course you should still prepare for tomorrow’s math exam. I recommend, as before, that you help each other study.
Between today and tomorrow you can get help at the QuaSRC and from Brian via e-mail.
No write-up is due this week on account of the math exam. Study study study! And of course your work from this workshop goes into your portfolio.
