Transforming the Equation of a Line Upon Axis Rotation: A Guide for SEO and Content Optimization

Introduction to Line Equation Transformation:

In this article, we explore the process of transforming the equation of a line when the axes are rotated by a specific angle. This is a fundamental concept in analytic geometry, with applications in various fields, including computer graphics, engineering, and data science. Understanding how to handle such transformations is crucial for optimizing content and improving search engine rankings. This guide will provide a detailed step-by-step process, complete with mathematical derivations and practical examples.

Axis Rotation and Its Impact on Equations

Axis Rotation in Coordinate Geometry

When the axes in a coordinate plane are rotated by a certain angle, the coordinates of a point in the plane change. This rotation affects how equations, particularly linear equations, are represented in the new coordinate system. The focus here will be on rotating the axes by 60 degrees.

Transforming the Original Line Equation

Consider the line 3x - 2y 1. Our goal is to find the new equation of this line when the coordinate axes are rotated by 60 degrees.

Step 1: Express the Equation in Slope-Intercept Form (Optional)

First, let's convert the given line equation into slope-intercept form y mx b.

3x - 2y 1

-2y -3x 1

y frac{3}{2}x - frac{1}{2}

The slope of the original line is -frac{3}{2}.

Step 2: Determine the New Coordinates

When the axes are rotated by an angle θ, the coordinates of a point P(x, y) in the original coordinate system transform to new coordinates x', y' in the rotated system using the following relations:

x x' cos theta - y' sin theta

y x' sin theta y' cos theta

For θ 60°, we have:

cos 60° frac{1}{2}, sin 60° frac{sqrt{3}}{2}

Substituting these values, we get:

x frac{1}{2}x' - frac{sqrt{3}}{2}y'

y frac{sqrt{3}}{2}x' frac{1}{2}y'

Step 3: Express New Coordinates in Terms of Original Coordinates

Our goal is to express x' and y' in terms of x and y. Solving the above system of equations simultaneously, we can express:

x' frac{1}{2}x frac{sqrt{3}}{2}y

y' frac{sqrt{3}}{2}x - frac{1}{2}y

Step 4: Substitute New Coordinates into the Original Equation

We substitute x' and y' back into the original equation 3x - 2y 1 to get the new equation in terms of the rotated axes.

3left(frac{1}{2}x frac{sqrt{3}}{2}yright) - 2left(frac{sqrt{3}}{2}x - frac{1}{2}yright) 1

Distributing the constants, we get:

frac{3}{2}x frac{3sqrt{3}}{2}y - sqrt{3}x y 1

Combining like terms, we obtain:

left(frac{3}{2} - sqrt{3}right)x left(frac{3sqrt{3}}{2} 1right)y 1

This is the equation of the line in the new coordinate system after a 60-degree rotation.
