Effect of Vertical Compression on the Cotangent Function

Oct 13, 2025 by wbrum.org 27 views

Introduction

In mathematics, the graph of a function can be transformed in various ways, including vertical compression. When the graph of the parent function $y=\cot (x)$ is vertically compressed to produce the graph of the function $y=a \cot (x)$ , but there are no reflections, we need to determine the value of $a$ . In this article, we will explore the concept of vertical compression and its effect on the graph of the cotangent function.

What is Vertical Compression?

Vertical compression is a type of transformation that involves shrinking or compressing a graph vertically. This means that the graph is compressed or shrunk in the vertical direction, resulting in a change in the scale of the graph. In the case of the cotangent function, vertical compression will result in a change in the amplitude of the graph.

Effect of Vertical Compression on the Cotangent Function

When the graph of the parent function $y=\cot (x)$ is vertically compressed to produce the graph of the function $y=a \cot (x)$ , the amplitude of the graph is reduced. This means that the graph will be compressed or shrunk in the vertical direction, resulting in a change in the scale of the graph.

Determining the Value of $a$

To determine the value of $a$ , we need to consider the effect of vertical compression on the graph of the cotangent function. Since the graph is compressed vertically, the amplitude of the graph is reduced. This means that the value of $a$ will be less than 1.

Analyzing the Graph

Let's analyze the graph of the cotangent function to understand the effect of vertical compression. The graph of the cotangent function has a period of $\pi$ and an amplitude of 1. When the graph is vertically compressed, the amplitude is reduced, resulting in a change in the scale of the graph.

Conclusion

In conclusion, when the graph of the parent function $y=\cot (x)$ is vertically compressed to produce the graph of the function $y=a \cot (x)$ , but there are no reflections, the value of $a$ will be less than 1. This means that the amplitude of the graph is reduced, resulting in a change in the scale of the graph.

Final Answer

The final answer is that the value of $a$ is less than 1.
