What is the trigonometric graph of cosine

The video tutorial explains how to graph the cosine function using the unit circle. It begins by introducing the concept of graphing cosine on an X&Y axis, then moves on to discuss the unit circle and its important points. The tutorial evaluates the cosine function at key angles, such as 0, π/2, π, and 3π/2 radians, and demonstrates how to plot these values on a graph. Finally, it describes the cosine curve's repeating pattern and how it extends in both positive and negative directions.
