Unit 4a OR Pre-Cal

4.2 Unit Circle

radians

pi/2, etc

this is a form of a measurement in the unit circle

degrees

circle is 360 self explanatory

using trig identities

we use trig identities in order to find certain degrees within the unit circle

speed drills

helps us better understand the unit circle and its values.

4.1 Learning about trig

SOHCATOA

sin, cos, tan

OPPOSITS

csc, sec, cot

finding side lengths with Trig

ex: sin(60) = 11/x

What I remember

Trig

I know confidently of the 8 basic trig identities

unit circle

I believe as though I can effectively utilize and rewrite the unit circle through memory

What to look forward to

I believe that knowing the basics of trigonometry will help me in the second part of this lesson and future classes
