• OUTLINE FOR MIDTERM 4:

BIG FILES: Sections 5.1-5.3Sections 5.4-5.5 and IDs Chapter 6Handout: “More Trig IDs” handout will be handed out in class. It is critical!

SMALLER FILES (if you can’t get the big files):

Chapter 5: Analytic Trig (61 pages)

Section 5.1 in Larson: Fundamental Identities (IDs)

Basic Trig IDs (handed out in class from Ch.4): Basic Trig IDs (also in 5.1 notes)

Section 5.2 in Larson: Verifying Trig IDs

Section 5.3 in Larson: Solving Trig Equations

Sections 5.4 and 5.5 in Larson: More Trig Ids

More Trig IDs (handed out in class): Handout. It is critical!

• DERIVATIVES OF TRIG FUNCTIONS (OPTIONAL)

We mentioned this at the end of Chapter 5. If you're curious, here are some calculus notes on this topic: Section 3.4 (pdf) from Math 150

Chapter 6: Additional Topics in Trig (38 pages of primary notes)

Section 6.1 in Larson: The Law of Sines

Section 6.2 in Larson: The Law of Cosines

Flowchart for Sections 6.1 and 6.2 (better for practical use than actual "memorization")

Section 6.3 in Larson: Vectors in the Plane

Section 6.4 in Larson: Vectors and Dot Products

Section 6.5 in Larson: Trig Form of a Complex Number
