## Last Class of 2019…

On December 20th (Day 1) we filled in our “letter to ourselves” for 2020.

Have a WONDERFUL break!  See you on January 6th!  🙂 Photo by Public Domain Pictures on Pexels.com

## Exponential Equations

On December 18th/19th we:

On December 19th (Day 2 only) we also worked on our letter to the 2020 version of ourselves and handed that in.

## Trigonometry Test

On December 16th/17th we had our test on the last two learning outcomes for this unit:

• L.O. 10: Demonstrate an understanding of how to use trig identities to solve problems.
• L.O. 11: Demonstrate an understanding of how to use trig identities to prove trigonometric statements.

We will be learning about solving exponential equations without logarithms next class. ## Exponential Functions

On December 12th/13th we:

On December 16th*/17th* (note that this date has been revised) we will be assessing the last two learning outcomes for this unit:

• L.O. 10: Demonstrate an understanding of how to use trig identities to solve problems.
• L.O. 11: Demonstrate an understanding of how to use trig identities to prove trigonometric statements. ## Trigonometry Equations Test

On December 10th/11th we:

On December 16th*/17th* (note that this date has been revised) we will be assessing the last two learning outcomes for this unit:

• L.O. 10: Demonstrate an understanding of how to use trig identities to solve problems.
• L.O. 11: Demonstrate an understanding of how to use trig identities to prove trigonometric statements. ## Review Day

On December 6th/9th we:

• went over our quizzes from L.O. 8
• discussed our upcoming test by going over L.O. 8 and 9
• were shown the link to the extra practice (here it is!)
• were shown the formula sheet Your unit test will be in two parts. On December 10th/11th we will be assessing the following learning outcomes:

• L.O. 8: Demonstrate an understanding of how to solve trigonometric equations algebraically (with a scientific calculator).
• L.O. 9: Demonstrate an understanding of how to solve trigonometric equations graphically (with technology).

On December 16th*/17th* (note that this date has been revised) we will be assessing the last two learning outcomes for this unit:

• L.O. 10: Demonstrate an understanding of how to use trig identities to solve problems.
• L.O. 11: Demonstrate an understanding of how to use trig identities to prove trigonometric statements.
