What is the first octant?
Understand the Problem
The question is asking for the definition or explanation of the term 'first octant'. The first octant is a concept used in three-dimensional coordinate systems to describe a specific region where all coordinates are positive.
Answer
The region in three-dimensional space where x, y, and z are all positive.
The first octant refers to the region in three-dimensional Cartesian coordinate system where all three coordinates (x, y, and z) are positive.
Answer for screen readers
The first octant refers to the region in three-dimensional Cartesian coordinate system where all three coordinates (x, y, and z) are positive.
More Information
In the Cartesian coordinate system, space is divided into eight regions called octants, similar to how the 2D plane is divided into four quadrants.
Tips
It's common to confuse octants with quadrants. Remember that quadrants apply to 2D spaces, and octants to 3D spaces.
