  1. HONORS PRECALC: Warm-Up 1.) Fill out the first quadrant of the unit circle (see if you can do it without looking). Check your work with the actual unit circle.

  2. Reminders • A little note: a lot of section 5.2 we have essentially already covered in Ch. 6 . • Quiz tomorrow on unit circle.

  3. Definitions of Trig Functions Recall that t is simply the distance around the unit circle (it is measured in radians) Un-shifted trig functions

  4. Evaluating Trig Functions

  5. Evaluating Trig Functions

  6. Even/Odd Even functions are symmetric over the y-axis Odd functions are symmetric about the origin

  7. Graphing the Sine Function • The sin and cosine functions have a period of 2π

  8. Graphing the Cosine Function

  9. Homework #12 • Be ready for a 5 minute unit circle quiz. • Section 5.2 Page 416: #4, 5, 6, 13, 19, 27, 29
