Graphs of Sine and Cosine Functions
Graphing is one of the most important tools available to scientists, engineers, and others in their efforts to understand functions. A graph characterizes a function’s behavior and is an easily remembered visual image of its properties. Data analysis and problem solving frequently involves the use of graphs and the insights they provide. Consequently, a thorough knowledge of the graphs of the elementary trigonometric functions as well as an understanding of techniques used to graph more sophisticated trigonometric waves is instrumental to the student of trigonometry.
This lesson presents the basic graphing strategies used to graph generalized sine and cosine waves from a conceptual point of view.
