Intro to Calculus (Class 60)
Lesson Title
Circular Functions (13)
Overview
During the opener students have a chance to confirm their solutions for Sangaku 13. Afterwards students will continue to work to build a stronger connections between relationships between angles and coordinates and the mathematical notation used to represent these relationships. During the last part of class, Test 6 will be returned. Solutions to version A of the test have been previously posted on the class website.

Key Attitudes
Math is about using what you know to create something new.
Key Ideas
An identity is an equation which is true for all values of the variable.
You can determine if an equation is an identity by graphing the two sides of the equation separately. If these are the same graphs, then its an identity.
Key Skills
I can simplify an expression involving trigonometric functions.
I can verify that an trigonometric equation is an identity by using a graphing calculator.
I can prove that an trigonometric equation is an identity by using algebra.
I can solve trigonometric equations including ones which require substitution.
I can translate between mathematical notation and English with regards to trigonometric functions and their inverses.
