Hello and welcome! Yesterday we talked about the sum and difference of angles. Today we will use the double angle identities to evaluate expression, to prove identities and finally to solve equations.
Here is the livestream key for today: https://youtu.be/aR-rEEQ_m2I
Here are the notes for today: Chapter 7 Lesson 8 Apply Double Angle Trig Identity
Reminder: Our Trig Identity and Equation Test is on Friday, June 12th. The last day to submit this test is on Monday, June 15. I had to have a FIRM AND FINAL due date because our school needs marks for report cards and for graduation.
