After our overview of linear regression today, complete the following questions before our next class.

Exercise 21B questions 1

Exercise 21D questions 3 and 4

Exercise 21E questions 4, 5, and 6

Now that we’ve covered the unit circle definitions together, complete the following questions before next class.

Exercise 8C questions 1, 2, 3, and 4 (this was already assigned last week, so make sure these are done for our next lesson)

Exercise 8E questions 1 and 2 (use the “new” definition \(\tan \theta =\frac{\sin \theta}{\cos \theta}\))

For years now you’ve been told that trigonometry is “all about triangles,” but now we’re going to make it “all about circles!”

Read through Section C of Chapter 8, then try the questions listed below. (We’ll be continuing with this material on Monday, but try to get as far as you can on your own before that class.)

Exercise 8C questions 1, 2, 3, and 4

Over the next two classes this week, you should be working on the following questions. (Check this list again on Wednesday, as more questions may be added!)
