Original Khojo Papers practice question — not from a past board paper.
The three coordinate planes divide space into eight octants. In the first octant all three coordinates x, y and z are positive.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
The octants are the three-dimensional counterpart of the four quadrants of the plane.
