1.) Sketch a 30-60-90 triangle and 45-45-90 triangle with side lengths included.
2.) What is the equation of a circle with a radius of 1?
3.) Take out your unit circle that I handed out about a week ago.

Day 1: The Unit Circle
Day 2: Trig Functions of Real Numbers
(Conic Sections project due Tuesday)
Day 3: 10 point quiz on the unit circle.
Day 4– Scavenger Hunt
SPRING BREAK!

Trig Functions of Angles
Trig Functions of Real Numbers
• In Chapter 6 we studied the trig functions of angles, in chapter
5, we study the trig functions of real numbers.

t is the distance around the unit circle (it is simply the angle in radians).

YOU TRY!!!

• Let’s see if you can fill in a unit circle!

• Complete and submit your conic sections project.
• Memorize the unit circle. Be ready to complete a unit circle
Wednesday (Thursday for period 1). You will have 5 minutes to do it. We will decrease the time later on.
• Use the end of class to try doing a unit circle independently.
