Day 14 in Mat121

Today:

• Roll
• Return Exam 1
  • The "Key"
  • Curve: linear transformation. Compute your new percentage as
    f(score)=100*score/45

    (45 rather than 60 -- high raw score: 51). After the curve, the exam statistics are:

    • mean: 75.3
    • sd: 17.2
    • median: 74.4

  • Special bonus offer: I'll drop your lowest test grade (not including the final).

• Directed reading handouts are coming... I felt it imperative to get the exam graded. I'll try to have those today: check the website. I'll certainly have a homework assignment for section 3.2.

• Section 3.2: The Derivative Function
  • The definition

  • The sum rule

  • The constant multiple rule

  • The product rule (from section 3.3)

  • The power rule
