We went over WS 13.4 Test Prep and collected the 13.4 packet from yesterday. We also put a timeline up for the end of the year. The last 2 assessments will be next week on May 22 and 23rd.

Then we looked at how to find the amplitude: |a|, frequency (b), and the period for a given cosine graph. Then we used those features to create the graph. The cosine graph starts at the "a" value (as long as there is no vertical shift).

HW: Complete the 13.5 packet except for the solving equations (11 - 16).
