Review of chapter including SOHCAHTOA and Pythagorean Theorem, classifying triangles, and solving for angles using inverse trig functions.

We finished our Chapter review. Since I wasn't here yesterday we will have the exam on Monday.

We bega the chapter review for a test on Thursday.

We discussed people's reactions to the Depression, and how Hoover responded.

Review of topics covered so far in this chapter (Pythagorean Theorem, SOHCAHTOA, and inverse functions), all used to solve for right triangles.

Solving for angles using inverse trig functions. Rowan needs to get a scientific calculator from any CVS, Walgreens, Walmart etc, so that he can work out these functions. It is about $10.

Review facts about the Great Depression in preparation for his test tomorrow.

Using models, have Rowan construct a butane molecule. On the board, expand the alkane series to the last 5 chains and add them to his list of the first 5. Impress that he will try to memorize, by using, the prefix names of the first 10 alkanes, and that they all end in ane. Take heptane as an example and write the molecular formula, the structural formula, the condensed structural formula and have Rowan determine how to condense the condensed.
