This week in Pre-Calc we learnd trigonometry. Trigonometry this year was quite different than last year, because we were working with non-right angle triangles. The reference angle in this years trigonometry is very important, because it helps us relate it to grade 10 trig, and because it can help us use our special triangles. The notes I took for this unit were very heavy, because we learned so many new math laws, like the sine and cosine law. When doing the review I was able to create a whole paper of notes, with the most importnat stuff put together.

This sheet is what I think the most important concepts to know are.
