(after Test 3)
Topic: graphing one period of sine and cosine functions:
Notes and a video of my slideshow with voiceover are in this post
Homework:
• Review the examples discussed in class, and start reviewing the unit circle.
• Do the WeBWorK assignments on the Unit Circle and on graphing trig functions (4 assignments, broken down). The recommended order to do them is as follows:
- Trigonometry – Unit Circle
- Trigonometry – Graphing Amplitude
- Trigonometry – Graphing Period
- Trigonometry – Graphing Phase Shift
- Trigonometry – Graphing Comprehensive
• Also make sure to do the following problems from the textbook:
p. 251 Exercise 17.6 a, b, c, d, f, g, (h was done in class), i, k
You may put one of these on the board at the start of class next time.
• Here are some useful videos from PatrickJMT to help with the review of the unit circle from today and next time:
Deriving points on the unit circle (using the two special right triangles and other things)
Remembering the important points on the unit circle: part one, part two.
(Remember that the points on the unit circle give you the cosine and sine of an angle, in that order.)
Remember that if you get stuck on any of the problems or have a question about any of the material, you can post a question to the Piazza discussion board.
