JavaScript graphic example: Archimedes spiral
1. Archimedes spiral Archimedes spiral is also known as “constant velocity spiral”. When a point P moves along the moving ray OP at the same speed, the ray rotates around the point o at the same angular speed. The trajectory of point P is called “Archimedean spiral”. The Cartesian coordinate equation of Archimedes spiral is […]
