PreCalculus

Since I failed to click "'post" and place the videos for last night's homework online, we will work thru the Examples on Video One from last night stopping to discuss various points along the way during each problem.

Afterwards we will work thru two problems from yesterday (55, 57) and work thru 58 as well.


HW take notes on the two remaining videos posted on Thursday's page.  Look ahead to Monday - page 378 (Half-Angle formulas) and work through Example 6.
