Today’s agenda • Greetings • Intro • Review HW: Domain & Range of: • sin and sin-1 • cos and cos-1 • tan and tan-1 • Lesson: Interval Notation, Inverses • Homework • Clean-up
Topics from Section 4-4 • Interval Notation: • [-3, 3] describes the set of x where -3 x 3. • (-3, 3) the set where -3 < x < 3. • [-3, 3) the set where -3 x < 3. • (-3, 3] the set where -3 < x 3.
Topics from Section 4-4 • Inverse sine & tangent • Know they exist • Know where to look them up • Know how to use them if you need them • Don’t bother memorizing them • Quadratic Equations with Trig Function Terms • Know how to solve • Know when they’re insoluble
Inverses • Theprincipal value of arctan3, i.e.,tan-13, is/3. • Find the other four values of arctan3in the graph shown. • Try to find a concise way to write the general solution for arctan3.
Homework • From Section 4-4: • Reading Analysis Questions • Q1-Q10 • Exercises 1-27 odd. • Due Friday 12/17.
Clean-up / Reminders • Pick up all trash / items. • Push in chairs (at front and side tables). • See you tomorrow!
