Graphing Approach - Precalculus With Limits: A

Compare the degrees of the numerator and denominator. 4. Trigonometry via the Unit Circle Coordinates: Remember

Use a graphing calculator to verify your hand-drawn sketches, not replace them.

The "Limit" describes the behavior of a function as it approaches a specific point. Precalculus with Limits: A Graphing Approach

If a graph looks weird, plot 3-5 specific points to anchor it.

Use the Leading Coefficient Test to see where the graph goes as Compare the degrees of the numerator and denominator

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

Master Precalculus with Limits: A Graphing Approach This guide focuses on mastering functions, trigonometry, and the introduction to calculus through a visual and graphical lens. 1. Master the Library of Functions The "Limit" describes the behavior of a function

Follow the line from both sides; if they meet at the same height, the limit exists. Algebraic View: Try direct substitution first; if you get , factor or rationalize.
