In certain mathematical contexts, the point $(1, 3, 2)$ might be used as an example for convenience or for demonstrating a concept. The choice of a point depends entirely on the specific context of the problem you're working with.

If you're working in 3D space, each point is represented by three coordinates: $(x, y, z)$, where $x$, $y$, and $z$ are real numbers that represent positions along the x-axis, y-axis, and z-axis, respectively.

• The point $(1, 3, 2)$ is one such point, located 1 unit along the x-axis, 3 units along the y-axis, and 2 units along the z-axis.
• Similarly, $(1, -1, 3)$ is also a valid point in 3D space, with its own unique location. Here, it's positioned 1 unit along the x-axis, -1 unit along the y-axis (indicating a position below the origin in the y-direction), and 3 units along the z-axis.

So, yes, you can certainly use other points like $(1, -1, 3)$ or any other coordinates as long as they are defined within the space (either 2D or 3D). The choice of points usually depends on the specific task, like finding distances, plotting points, or solving equations.

1. How do you calculate the distance between two points in 3D space?
2. What is the geometric meaning of a point in 3D space?
3. How do you find the midpoint between two points, such as $(1, 3, 2)$ and $(1, -1, 3)$?
4. Can you explain how vectors are represented using points in 3D space?

Tip: When visualizing points in 3D space, it helps to sketch or use graphing software to see the spatial relationships more clearly!
