GoMim AI | What is distance formula and How to Calculate it

Introduction

In the realm of mathematics, the distance formula is a fundamental concept that helps us measure the distance between two points in a coordinate plane. This formula is essential not only for geometric calculations but also for real-world applications such as navigation, engineering, and data analysis. By understanding the distance formula, students can enhance their problem-solving skills and apply mathematical concepts to practical situations.

What is it?

The distance formula is a mathematical equation used to determine the distance between two points in a two-dimensional plane. If you have two points, \((x_1, y_1)\) and \((x_2, y_2)\), the distance \(d\) between them can be calculated using the distance formula: $$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$ This formula is derived from the Pythagorean theorem, where the distance between the points represents the hypotenuse of a right triangle formed by the horizontal and vertical distances between the points.

Why is it important?

The distance formula is crucial in various fields of study and practical applications. In academics, it is commonly used in geometry, trigonometry, and calculus to solve problems related to distance and measurement. For example, it is essential for calculating the length of a line segment or the radius of a circle. In real-world applications, engineers use the distance formula to design and analyze structures, ensuring they are safe and functional. In data analysis, it helps in clustering algorithms and calculating the similarity between data points. Additionally, in navigation and GPS technology, the distance formula is fundamental for determining the shortest path between locations.

How to Calculate it Step-by-Step

To calculate the distance between two points using the distance formula, follow these steps: 1. Identify the Coordinates: Determine the coordinates of the two points you want to measure. For instance, let the points be \((x_1, y_1)\) and \((x_2, y_2)\). 2. Subtract the Coordinates: Compute the differences between the corresponding coordinates of the two points: - \(x_2 - x_1\) - \(y_2 - y_1\) 3. Square the Differences: Square the differences obtained in the previous step: - \((x_2 - x_1)^2\) - \((y_2 - y_1)^2\) 4. Add the Squares: Add the squared differences: - \((x_2 - x_1)^2 + (y_2 - y_1)^2\) 5. Take the Square Root: Finally, take the square root of the sum to find the distance: - \(d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\) Example: Let's calculate the distance between the points \((3, 4)\) and \((7, 1)\): 1. Identify the coordinates: \((x_1, y_1) = (3, 4)\), \((x_2, y_2) = (7, 1)\) 2. Subtract the coordinates: \(7 - 3 = 4\), \(1 - 4 = -3\) 3. Square the differences: \(4^2 = 16\), \((-3)^2 = 9\) 4. Add the squares: \(16 + 9 = 25\) 5. Take the square root: \(d = \sqrt{25} = 5\) Thus, the distance between the points is 5 units.

Related Practice Problem

Problem: Calculate the distance between the points \((2, -1)\) and \((5, 3)\) using the distance formula.

Step-by-step Solution:

1. Identify the coordinates: \((x_1, y_1) = (2, -1)\), \((x_2, y_2) = (5, 3)\) 2. Subtract the coordinates: \(5 - 2 = 3\), \(3 - (-1) = 4\) 3. Square the differences: \(3^2 = 9\), \(4^2 = 16\) 4. Add the squares: \(9 + 16 = 25\) 5. Take the square root: \(d = \sqrt{25} = 5\) The distance between the points is 5 units.
