Chapter Overview
This chapter introduces the concept of three-dimensional geometry, expanding upon two-dimensional coordinate geometry. Students will learn how to represent points in space using x, y, and z coordinates. The chapter focuses on the distance between points, the section formula, and basics of vectors in 3D geometry. These concepts are crucial in physics, engineering, and advanced mathematics.
Important Keywords
- 3D Coordinate Axes: The three mutually perpendicular lines: x-axis, y-axis, and z-axis.
- Origin: The point of intersection of the three axes, denoted as (0, 0, 0).
- Coordinates: An ordered triplet (x, y, z) representing the location of a point in space.
- Octants: The eight parts into which the three axes divide space.
- Distance Formula: Calculates the straight-line distance between two points in 3D space.
