Use a graphing calculator to verify your hand-drawn sketches, not replace them.
Identify Amplitude (height), Period (length of one cycle), and Phase Shift (horizontal slide). Identities: Use Pythagorean identities ( ) to simplify expressions before graphing. 5. Limits: The Bridge to Calculus Precalculus with Limits: A Graphing Approach
The "Limit" describes the behavior of a function as it approaches a specific point. Use a graphing calculator to verify your hand-drawn
