Hi Everybody, Re: Displaying all roots of a number - Michael Andersson - 06-03-2008
Hi, For example to find all the fifth roots to 2+3i transform this into the equation -z^5+(2+3i)=0, on the 50g put [ -1 0 0 0 0 (2,3) ] (where the zeros are the coefficients for z^4 down to z^1) on the stack and press PROOT (found under "NUM.SLV"/"POLY").
The results is (approximately): Hope this works.
