Sketching Graphs of Trigonometric Functions

As evidenced by their name, graphing calculators have the capability not just to evaluate small or large trigonometry expressions but also to graph their values over a specific domain. Although the specific graphing utilities across various calculator models can be different in terms of layout and specific keys to press, they all follow several common design principles.
