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.
