Graphing a Cosine Function with a Horizontal Shift

The video tutorial covers graphing trigonometric functions, focusing on amplitude and period. It explains how to determine these values and apply them to graph cosine functions. The tutorial also discusses horizontal translations and how to adjust graphs accordingly. Techniques for dividing the period into sections for accurate graphing are demonstrated, along with methods for applying translations to graphs. The tutorial concludes with finalizing the graph by considering amplitude and translations.
