Email: wlaw@vsb.bc.ca

We started Chapter 6 today (6.1). We looked at 8 different videos with a 15 second clips and tried to draw the corresponding graph to the movement. The videos are from graphingstories.com.
Reminder: Test next class. Puzzle 78: Switch Positions We have an inclass practice period today in preparation for the test next Tuesday. Students are given worksheets to practice on. Puzzle 91: How many 1's?
We finished our example from last class and looked at multitriangles problems. We have time to do two Ted Ed riddles (the bridge riddles and the passcode riddle). Students are given practice questions and a worksheet on angles of elevation/depression for practice over the winter break. Practice: Chapter 3.3 Page 48 # 1, 2, 4, 5, 7
We looked at what it means to "solve a right triangle." Plus, we discussed angle of elevation and angle of depression.
Announcement: Test 4 on Trigonometry on Jan 15, 2019 Tuesday during class time. Puzzle 23: Sequencing Cards We did some review before the quiz today. Quiz 3 completed today. We also went to a holiday celebration at the foods room.

We went through the 2 worksheets from last class. And then, we looked at the Sine and Cosine ratios. We introduced the acronym "SOH CAH TOA." We also discussed on how to find the length if the unknown is at the denominator (ie. looking for the hypotenuse in cases of sine and cosine or adjacent in the case of tangent).
