Trig intro: U4 intro to trig.pdf (hard copy in class)

HW:

• Do p. 290/1-69 odd (I don't want this to be busy work- if you feel that you learn best by just doing one from each section, then feel free to do so)
• Memorize the common radian-degree conversion: this flashcard site may help you to quiz yourself and this circle will help you visualize the angles (turn off the coordinates if they get in the way)
