Today:

• Roll
• Homework/directed reading handout: Section 2.2 (html) (pdf)

• Chapter 1 (cont.)
  • Questions regarding Homework/directed reading handout: Chapter 1 (html) (pdf)

  • Some basic plotting on the TI-92
    • Defining/storing functions
    • Using lists to advantage in plots

  • Roots -- using solve on the TI

  • A scaling and transformation exercise -- modelling "misplaced" sin information

  • A composition exercise

  • Section 2.1: Limits, Rates of Change, and Tangent lines
    • So: what are
      • Limits,
      • Rates of Change, and
      • Tangent lines,
      and how are they related?

    • We start with velocity:
      • How is it defined in terms of position and time?
      • What are its units?
      • Consider first uniform motion: each time interval T gives the same change in position (graph)
      • What happens as motion is no longer uniform?

    • Instantaneous ROC -- how do we get at it?
