Graphing the Cosine Graph

The video tutorial explains how to find the period and amplitude of a function, specifically focusing on the cosine graph. It covers the calculation of amplitude using the absolute value of 'a' and determining the period using 'B'. The tutorial also demonstrates graphing the cosine function by identifying key points and extending the graph for additional periods. The session concludes with a reminder of the infinite nature of cosine graphs and encourages practice through homework.
