Trigonometric Identities Review
We had learned about the trigonometric identities beforehand, but we never actually memorized them all! In a lesson this week, we learned that we need to memorize all forty eight! We have started slow with practicing the 11 fundamental ones on a worksheet, but we will gradually have to review more. The identities will help us all in many ways in Calculus if we choose to take it next year. The identities help us manipulate equations concerning angles to the simplicity or complexity that we desire. It will be invaluable for students in calculus next year because they will be able to do problems way faster and easier. Below, I have a picture of most of the identities:

Thanks for posting a picture of the trigonometric identities. I think I lost mine. At the end of the semester we will need to be know all 48 identities by heart. This will be hard but it will help us in the long run for Calculus. If we know all these identities it will help us to do everything faster and better. This will help us in the future.
