Complex Roots

2008-12-31 by joecolannino

Does anyone have a program written for the HP 50G that will give all
complex roots of a number? For example,the cube roots of -1 are
{[1+sqrt(3)]/2, -1, and [1-sqrt(3)]/2 } but the HP 50G will give only
the first. Trying to evaluate the cube root of 2+11i it chokes
altogether though the answers are clearly {2+i, -1.866+1.232i
(approx), -0.1340-2.232i (approx)}.
