Today we answered Circle questions from Section 4.7 involving circles that had the x or y-axis as tangents (click here).

We then started Chapter 5: Trigonometry 2. There are 8 trigonometric identities that we are required to derive. Today we looked at the proofs of the first 3 of these including proofs of the Sine and Cosine Rules (click here).

HW: Learn these 3 derivations.
