# Find The Distance Between The Points (a, 0) And (0, b). – A Simple Calculation When it comes to finding the distance between two points on a coordinate plane, such as (a, 0) and (0, b), there is a simple formula that can be employed. This formula, known as the distance formula, allows us to calculate the distance between any two points in a Cartesian coordinate system. By applying this formula to our given points, we can determine the precise distance between them.

The distance formula states that the distance between two points with coordinates (x1, y1) and (x2, y2) is equal to the square root of [(x2 – x1)^2 + (y2 – y1)^2]. In our case, since one point has an ordinate of 0, we will only need to consider the difference in abscissa values. Therefore, our calculation simplifies to d = sqrt[(a – 0)^2 + (0 – b)^2].

## Find The Distance Between The Points (A, 0) And (0, B).

### Calculating the distance using the Pythagorean theorem

When it comes to finding the distance between two points in a coordinate system, one method that proves to be incredibly useful is utilizing the Pythagorean theorem. This theorem, which you may recall from your math classes, establishes a relationship between the lengths of the sides of a right triangle. In our case, we can apply it to determine the distance between two points: (a, 0) and (0, b).

To calculate this distance using the Pythagorean theorem, we need to consider these points as vertices of a right triangle. The horizontal difference between them represents one side of the triangle, while the vertical difference represents another side. We can then use these differences as inputs for our calculation.

### Understanding the coordinates (a, 0) and (0, b)

Before delving further into finding distances using formulas or equations, let’s take a moment to understand what exactly those coordinate pairs (a, 0) and (0,b) represent on a graph. These pairs denote specific locations within an x-y plane.

In terms of (a , 0), ‘a’ corresponds to its position along the horizontal x-axis while ‘0’ signifies its position along the vertical y-axis. Similarly for (0 , b), ‘b’ indicates its position on the y-axis while ‘0’ denotes its position on x-axis.

By identifying these coordinates, we can visually comprehend the positioning of the points and better grasp their relationship, aiding us in determining the distance between them.

### Exploring the formula for finding distance between points

Now that we have a solid foundation on coordinates and understanding how to apply the Pythagorean theorem, let’s explore a formula specifically designed for calculating the distance between two points in a coordinate system.

The formula is derived from the Pythagorean theorem itself. By plugging in our values for x and y differences (|a – 0| = |a| and |b – 0| = |b|) into its respective spots, we arrive at:

distance = √(|a|^2 + |b|^2)

## Understanding The Coordinate System

In order to find the distance between two points on a coordinate plane, it’s important to have a clear understanding of the coordinate system. The coordinate system consists of an x-axis and a y-axis, which intersect at the origin (0,0). Each point on the plane is represented by an ordered pair (x,y), where x corresponds to the position along the x-axis and y corresponds to the position along the y-axis.

Here are a few key concepts to keep in mind when working with coordinates:

1. X-Axis: The x-axis is a horizontal line that extends infinitely in both positive and negative directions. It acts as a reference for measuring distances horizontally.
2. Y-Axis: The y-axis is a vertical line that also extends infinitely in both positive and negative directions. It serves as a reference for measuring distances vertically.
3. Origin: The origin is located at (0,0) where both axes intersect. It serves as a starting point for measuring distances between other points.
4. Quadrants: The coordinate plane is divided into four quadrants – I, II, III, and IV – each representing different combinations of positive and negative values for x and y coordinates.

Now that we have familiarized ourselves with these fundamental elements of the coordinate system, we can proceed to find the distance between two specific points (a, 0) and (0, b). By using Pythagoras’ theorem or applying basic geometry principles such as right triangles formed by connecting these points with straight lines to the origin or axes, we can calculate this distance accurately.

By understanding how coordinates work within this system, we can easily navigate through mathematical problems involving distances between points on a plane. This knowledge will not only help us solve specific problems but also lay down a solid foundation for further exploration into more complex concepts related to coordinates and their applications in various fields such as physics, engineering, and computer science.
