In the realm of mathematics, equations often serve as powerful tools for describing relationships between variables. Among these equations, one particular form stands out for its elegance and significance:Equation x² + (y – 3√2x)² = 1. This equation, with its intricate structure, holds deeper meaning and possesses profound implications across various mathematical domains. In this article, we embark on a journey to unravel the secrets encapsulated within this equation, exploring its meaning and unveiling the proof that underlies its validity.

Understanding the Equation

Before delving into the intricacies of the equation x² + (y – 3√2x)² = 1, it is essential to dissect its components and understand their individual significance. At first glance, the equation may appear daunting, but breaking it down reveals its underlying elegance. The term x² represents the square of the variable x, while (y – 3√2x)² denotes the square of the expression (y – 3√2x). The sum of these two terms equals 1, implying a certain relationship between x and y within the confines of this equation.

Meaning Behind the Equation

The equation x² + (y – 3√2x)² = 1 holds significant geometric implications, particularly in the context of conic sections. By interpreting this equation geometrically, we can discern its representation as an ellipse. An ellipse is a closed curve that exhibits a unique symmetry, characterized by two distinct foci and major and minor axes. In the case of x² + (y – 3√2x)² = 1, the presence of the square terms in both x and y coordinates suggests the elongation and rotation of the ellipse along the axes.

Furthermore, the coefficient 3√2 attached to the x-term within the expression (y – 3√2x) introduces a scaling factor, influencing the orientation and dimensions of the ellipse. This scaling factor contributes to the elongation of the ellipse along the y-axis, resulting in a distinct elliptical shape that differs from a standard circle.

Proof of Validity

To establish the validity of the equation x² + (y – 3√2x)² = 1, we employ mathematical techniques rooted in algebraic manipulation and geometric reasoning. Beginning with the equation itself, our goal is to demonstrate that it indeed describes the geometric properties of an ellipse.
