In this warm-up exercise, students will fill out the first quadrant of the unit circle to reinforce their understanding of trigonometric functions. They are encouraged to complete this task without references and then verify their answers using the actual unit circle. Important reminders include the connection to previously covered content in Chapter 6 and a quiz on unit circle definitions. Students will review even and odd functions, graph the sine and cosine functions, and prepare for a brief assessment. Homework and practice problems are assigned for further mastery.

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.
Reminders • A little note: a lot of section 5.2 we have essentially already covered in Ch. 6 . • Quiz tomorrow on unit circle.
Definitions of Trig Functions Recall that t is simply the distance around the unit circle (it is measured in radians) Un-shifted trig functions
Even/Odd Even functions are symmetric over the y-axis Odd functions are symmetric about the origin
Graphing the Sine Function • The sin and cosine functions have a period of 2π
Homework #12 • Be ready for a 5 minute unit circle quiz. • Section 5.2 Page 416: #4, 5, 6, 13, 19, 27, 29
