Introduction

In mathematics, a three-dimensional Cartesian coordinate system is a fundamental concept used to represent points in space. It is a system of coordinates that uses three perpendicular lines, known as axes, to locate a point in a three-dimensional space. The standard notation for a point in a three-dimensional Cartesian coordinate system is a crucial concept to understand, as it is used extensively in various fields, including mathematics, physics, engineering, and computer science. In this article, we will explore the standard notation for a point in a three-dimensional Cartesian coordinate system and examine the options provided.

What is a Three-Dimensional Cartesian Coordinate System?

A three-dimensional Cartesian coordinate system is a system of coordinates that uses three perpendicular lines, known as axes, to locate a point in a three-dimensional space. The three axes are typically labeled as x, y, and z, and they intersect at a point called the origin. The x-axis is horizontal and extends left and right from the origin, the y-axis is vertical and extends up and down from the origin, and the z-axis is perpendicular to the x and y axes and extends forward and backward from the origin.

Standard Notation for a Point in a Three-Dimensional Cartesian Coordinate System

The standard notation for a point in a three-dimensional Cartesian coordinate system is a set of three numbers, known as coordinates, that represent the location of the point in space. The coordinates are typically written in the form (x, y, z), where x is the x-coordinate, y is the y-coordinate, and z is the z-coordinate.

Analyzing the Options

Now that we have a clear understanding of the standard notation for a point in a three-dimensional Cartesian coordinate system, let's analyze the options provided:

Option A: ${$ (x, y, z)$}$: This option represents the standard notation for a point in a three-dimensional Cartesian coordinate system, where x is the x-coordinate, y is the y-coordinate, and z is the z-coordinate.
Option B: ${$ (w, x, y)$}$: This option is incorrect because it uses the variable w instead of z, which is the standard notation for the z-coordinate.
Option C: ${$ (x, y, y)$}$: This option is incorrect because it uses the same variable y for both the y and z coordinates, which is not the standard notation.
Option D: ${$ x, y, z$}$: This option is incorrect because it does not use parentheses to enclose the coordinates, which is the standard notation.

Conclusion

In conclusion, the standard notation for a point in a three-dimensional Cartesian coordinate system is (x, y, z), where x is the x-coordinate, y is the y-coordinate, and z is the z-coordinate. This notation is widely used in mathematics, physics, engineering, and computer science to represent points in space. The options provided, with the exception of option A, are incorrect because they do not follow the standard notation.
