Graphing Cotangent with a Reflection

The video tutorial explains how to graph the function Y = -1/4 cotangent(X - π/2). It covers various transformations including reflection over the X-axis, horizontal stretching, and phase shifts. The period of the cotangent function is determined, and critical points such as X-intercepts and asymptotes are identified. The tutorial demonstrates graphing the initial period and adjusting the graph for transformations, resulting in a cotangent graph that resembles a tangent function after reflection.
