How to find the range of the sine and cosine graph

The video tutorial explains the concepts of domain and range in functions, focusing on sine and cosine. It uses the unit circle to evaluate these functions, highlighting the importance of angles and the radius. The tutorial demonstrates graphing sine and cosine, emphasizing the range of these graphs, which is between -1 and 1. It concludes by summarizing the range of trigonometric functions, including cotangent.
