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.

What is the significance of the intercepts in the cosine graph?

• They indicate the maximum points.

• They indicate the minimum points.

• They indicate the end of the graph.

• They indicate where the graph crosses the x-axis.

What should you remember about the cosine graph?

• It extends infinitely in both directions.

• It is a straight line.

• It only goes to the right.
