Day 21 in Mat122

Today:

• Announcement:

  The Department of Mathematics will hold a Major/Minors Lunch from 11:30am-1:30pm on Friday, November 30. All mathematics majors and minors are welcome (or even those thinking about it -- hungry for math!;). This is a great opportunity to get together with other students and faculty on a very informal basis, and learn more about a math major.

• Directed reading handout: Section 6.5 (html) (pdf)

• Return of Section 6.2 homework
  • "participation" was poor
  • These problems will haunt you: if you didn't do this particular homework set, you're making two mistakes:
    1. You received no points for the homework; and
    2. You're going to see this stuff again on a test, and you won't have practiced.
    It's hard, but so is life.... Don't think that I'm going to give you a get-out-of-integration-free pass. I don't mind giving hard problems.

• 6.3 homework will be due Friday

• Section 6.4:
  • The definition of "cylindrical shells":

    

    Which we refine....

  • Examples:
    • #16, p. 332 (use Newton's method)
    • #33-38, p. 333
