Day 29, Mat119: Pre-Calculus

• Homework 5.3, 5.4 not graded yet -- sorry.

• Today is the last day to withdraw with a grade of "W". Some of you may want to consider it. Talk to me if you are thinking about it...

• Our second test is returned:
  • Curve: +3 to your raw score.
  • Mean: 73.2
  • Median: 74.2
  • StdDev: 12.6
  • The exam
  • The key
  • Some observations:
    1. When I ask you to explain, you need to!:)
    2. Problem 2: a lot of you forgot about long division
    3. Problem 3e: explain why
    4. Problem 4b: Why not draw?
    5. Problem 5: straightforward law of cosines
    6. Problem 6: tricky (ambiguous) law of sines

Any questions?
