Tonight's Homework will be out of the book, just some practice solving for arcsin, arccos, arctan of specific values.

REMEMBER arcsin(1/2) just means "the angle whose sin is 1/2"
Pg: 316
#1,2,4,6

If you are checking your answers in the back of the book some of them are not between 0 and 2π

 (this is because of something we haven't covered yet called restricted domain, don't worry about that yet) I will make up a key with all the answers and hand it out tomorrow, if you want to check your answers yourself just find the coterminal angle.

Friday: We will start class with a unit circle quiz!

• You will have 15 minutes to completely fill out a unit circle
• Label all angle measures in radians
• Label all coordinate pairs
• You have to know this stuff!
• Section 4.7 is going to involve two new graphs, and then the rest of the section will be entirely based on your knowledge of the unit circle!
• We'll also see the unit circle again in chapter 5!
• Watch some videos, review your old notes, do whatever you have to do--BE PROACTIVE IN LEARNING YOUR UNIT CIRCLE! No excuses!

April Vacation: We will have a take home test over April break that reviews the following...

• Graphing sine and cosine with changes to amplitude, period, vertical shifts, and phase (horizontal) shifts (review)
• Graphing tangent, cotangent, secant, and cosecant
• Evaluating trig functions on the unit circle
• Working backwards with the unit circle...
• For example, "If the sin(x) = 1/2, what two angle measures could x have been?"
