- More food!
Major-Minor Lunch: The first Mathematics Student Lunch of the Fall 08 semester will take place on Friday, October 3 in ST 343 from 11:30am to 1:30pm. This is a great opportunity to welcome new students interested in the Mathematical Sciences, chat with professors and take up with old friends. Stop by when ever you schedule allows.
- If you'd like to hand in your written work for Section 7.3 so that I can
use it to better grade your on-line work, please do so at this
time.
- Section 7.8 homework: pp. 397-399, #1, 2, 6, 10, 17, 18, 21, 57 will be done on-line; problems 50, 83, and 84 will be handed in separately. Due Friday, 9/19.
- Examples:
- A better proof of the fact that
(take logs! Better than induction....)
- Proof of L'Hopital's Rule
- A better proof of the fact that
- For example, the sine function has inverse function
arcsin (note the bad notation below -- don't be confused! But our notation in mathematics is sometimes "context sensitive"):
and cosine function has inverse function arccos:
- Arctan and arccot are also sometimes useful:
- Derivatives: They're computed in the usual "sneaky" inverse function way:
Exercise 49, p. 398
- Examples:
- #50, p. 398
- #85, p. 399
