Precalculus With Limits: A Graphing Approach Here

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

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

Find x-intercepts and determine "multiplicity" (does the graph cross or bounce?). Asymptotes: Vertical: Where the denominator equals zero. Compare the degrees of the numerator and denominator

If a graph looks weird, plot 3-5 specific points to anchor it. Period (length of one cycle)
