Understand how to find the important characteristics of cotangent

The video tutorial covers transformations in trigonometric functions, focusing on phase shifts, vertical transformations, and the absence of amplitude in certain cases. It explains the cotangent function, identifying where it becomes undefined and how to calculate asymptotes with a period change. The tutorial also discusses the reflection of functions and demonstrates graphing techniques using Desmos.

Discuss the impact of a negative sign in the cotangent function.

How does the unit circle relate to the undefined values of the cotangent function?
