Intro to Calculus (Class 49)
Announcements
Very possibly there will be a quiz on Friday focusing on radians and coterminal angles.
Lesson Title
Circular Functions (3)
Overview
Our opener for the day will be focused on comparing answers and approaches for solving Sangaku 9. The remaining time will be spent working on Workshop 14.
Textbook Sections
N/A
Vocabulary
radian
central angle
terminal side
circumference
rotation
Key Attitudes
Math is about using what you know to create something new.
Key Ideas
Given two points on the circumference of a circle, one of the points can be rotated around the center to match up with the other point in an infinite number of ways.
Key Skills
I can explain what a radian is.
I can give a mathematical reason for why radians are “better” than degrees.
I can find the location of a point on the circumference of a circle resulting from a rotation about the center of the circle using radians.
I can determine the quadrant that a point on the circumference of a circle will end up in as the result of a rotation about the center given in radian.
I can determine the measure of coterminal angles.
