Our second midterm will be on Friday, May 27. It will cover everything we do up to that time, after the first midterm: in class (after April 27), in the homework (assigned after April 27), and in the book.
For the book, that means the nine sections:
7.4 (to page 440),
8.1,
8.2 (to page 501),
9.4 (to page 597),
10.1,
10.2 (except 10.2.2),
10.3,
10.4.1,
10.5.3.
Here is a summary of three models of
population growth in pdf format.
For the homework, it means all
55 problems assigned from these sections.
(Here is a link to answers to problems
that have been turned in.)
Ground rules: Paper will be provided. Bring pencil and eraser. No calculators (an answer of pi/ ln 2 should be left like that). Closed book (no note cards). Please bring your photo ID to the tests.
The test problems will be mostly like the homework. ("Mostly" means mostly, and "like" means that I think similar methods are used.) Answers should be supported by the work shown.
I will hold a "last chance" question-and-problem session on Thursday, May 26, 5:30 pm, in Geology 3656. And questions can always be posted on our virtual office hours board.
