Essential Question: How do we graph the inverse trig. functions?  
In Class: Today we went over how to graph the inverse of sine, cosine, and tangent. One method that we focused on was making a table using the coordinate points on the parent function and switching the values to find the inverse. We also talked about the importance of concavity. At the end of class, we were asked to solve the problem: 2 cos(x) -1=0. Mrs. Prior left us to think about how many solutions that equation would have.
Homework: page 288 #1-14 and #29-40. Tomorrow we have a quick quiz on graphing trig. functions!
