Why this matters
When Descartes drew two crossing axes, he did something incredible: he made geometry solvable by algebra. Now every shape has coordinates, and every equation has a picture.
GPS coordinates. Video-game physics. CAD software. Machine-learning models. The single most-used idea in modern engineering.
The story arc
- Class 7First coordinates — connecting the dots.
- Class 9Cartesian plane, distance and midpoint formulas.
- Class 10Section formula and area of a triangle from coordinates.
- Class 11Straight lines, conic sections, first taste of 3D.
