The Cosine Ratio

We reviewed our previous work with trigonometry so far this morning, and then took a look at our third and final ratio-the Cosine.

Pictured below are some notes courtesy of H-Thanks. If you have any questions be sure to comment. On Monday we will take up your assignment (pg 244 #1-34) and we'll mark the trig review. Maybe a quiz on Tuesday...



Have a great weekend.
