Topics:
• Using the Law of Cosines to find an angle in the SSS situation (Example 3, section 7.2)
• Trigonometric Identities (active learning worksheets)
You can see the handout online here:
We worked through all of part (1), and part (2)a-c, and part (3)a
At home you should complete (2) and (3), but please do not do the rest of the worksheet. We will be working on it together in class again on Monday.
Homework:
• Review using the Law of Cosines to find an angle. There is also an example of this in the Math is Fun webpage on the Law of Cosines. Or, you can view the Khan Academy video. or Patrick’s Just Math Tutorials.
• From section 7.2 in the Trig textbook, do #21-29 odd
• Complete parts (2) and (3) from the Trigonometric Identities worksheet. Do not go any further in the worksheet yet. This means that you should have completed up to the end of page 5 in that worksheet. You will work on the remaining pages together with your partner on Monday.
• Do the WeBWorK: due by 11 PM Sunday, start early! on the Law of Cosines.
• Don’t forget that Test 4 is scheduled for Wednesday 17 May. The review self-tests will be posted separately as soon as they are ready.
You may also want to take a look at the Math Department’s Final Exam review sheet. You will be able to sign up in class for a problem to present on the last class meeting day before the Final Exam.
Remember that you can use the Piazza discussion board to ask questions if you get stuck on any of the WeBWorK or the other homework problems. Don’t forget to include the problem itself in your question, as that will make it easier for you to get a quick response!
