Introduction

The tangent function, denoted as tan(x), is a fundamental concept in trigonometry and is used to describe the ratio of the opposite side to the adjacent side in a right-angled triangle. In mathematics, the tangent function is used to model various real-world phenomena, such as the motion of objects, the behavior of electrical circuits, and the growth of populations. In this article, we will explore how to find an equation for a graph using the tangent function.

Understanding the Tangent Function

The tangent function is defined as the ratio of the sine and cosine functions:

tan(x) = sin(x) / cos(x)

The tangent function has a periodic nature, with a period of π (180°). This means that the graph of the tangent function repeats itself every 180°. The graph of the tangent function has a vertical asymptote at x = π/2 (90°), where the cosine function is zero.

Graphing the Tangent Function

To graph the tangent function, we can use the following steps:

  1. Identify the period: The period of the tangent function is π (180°).
  2. Identify the vertical asymptote: The vertical asymptote of the tangent function is x = π/2 (90°).
  3. Plot the graph: Plot the graph of the tangent function using the identified period and vertical asymptote.

Finding an Equation for the Graph

To find an equation for the graph of the tangent function, we can use the following steps:

  1. Determine the amplitude: The amplitude of the tangent function is 1.
  2. Determine the period: The period of the tangent function is π (180°).
  3. Determine the vertical shift: The vertical shift of the tangent function is 0.
  4. Determine the horizontal shift: The horizontal shift of the tangent function is 0.
  5. Write the equation: Using the determined parameters, we can write the equation for the graph of the tangent function:

y = tan(x)

Example 1: Graphing the Tangent Function

Let's consider an example where we want to graph the tangent function with a period of 2π (360°) and a vertical shift of 2.

  1. Identify the period: The period of the tangent function is 2π (360°).
  2. Identify the vertical asymptote: The vertical asymptote of the tangent function is x = π (180°).
  3. Plot the graph: Plot the graph of the tangent function using the identified period and vertical asymptote.

The equation for the graph of the tangent function is:

y = tan(x) + 2

Example 2: Finding an Equation for the Graph

Let's consider an example where we want to find an equation for the graph of the tangent function with a period of π (180°) and a vertical shift of 1.

  1. Determine the amplitude: The amplitude of the tangent function is 1.
  2. Determine the period: The period of the tangent function is π (180°).
  3. Determine the vertical shift: The vertical shift of the tangent function is 1.
  4. Determine the horizontal shift: The horizontal shift of the tangent function is 0.
  5. Write the equation: Using the determined parameters, we can write the equation for the graph of the tangent function:

y = tan(x) + 1
