They are Radius and Theta coordinates. Radius is how far away it is from the origin, and the Theta is the direction where it's supposed to go. Theta is in radians. (0 ~ 2pi). * Prime Numbers * We use Polar Coordinates to graph the prime numbers. The Radius and Theta is the prime number, then we draw it out. The PRIME list is a list of primes ranging from 1 ~ 1,000,000. * Learn More * 3Blue1Brown - https://www.youtube.com/watch?v=EK32jo7i5LQ
