Web28 Nov 2014 · 1. Here's a recursive algorithm that generates the n roots by taking the n/2 roots and the points in between. If n is 4 or lower, it hardcodes the result (because you'll never find the two midpoints of -1 and 1 on the complex plane). Otherwise, it finds the n/2 roots, takes every two consecutive roots, finds a point on their angle bisector, and ...
