Identify the Reflections, Period and Domain of the Cotangent Function

The video tutorial covers the reflection of functions on the X-axis, horizontal compression, and its impact on trigonometric functions' periods. It explains how the period changes for sine, cosine, tangent, and cotangent functions. The tutorial also guides identifying asymptotes for cotangent graphs, emphasizing the changes in domain and period when the period is divided by three.
