It's just a coincidence

If you write the numbers out from 1 to 30, then cross out all the even numbers, then cross out any number that is divisible by 3,5,7 or 9, what remains are the root angles. You can plot the result in polar coordinates, or in linear coordinates. Either way the pattern is easily visible. And within it is the subset containing all prime numbers. There does not appear to be any simple way to reduce it to a single formula for the nth prime number.

    All prime numbers P are a subset of SP = {2,3,5, and R + n x 30} where R = {1,7,11,13,17,19,23,29} n = {0,1,2,3,... } P is prime if (P mod SP) 0 It's simpler I suppose, but it loses the perspective... more

        It is basically a plot of all odd numbers. The only reason they are prime numbers is because they've been checked beforehand to eliminate odd numbers that are multiples of smaller numbers. Every... more
