radicalSolve(x^5-1,x) gives results with sin and cos, but (x^5-1)= (x-1)*(x^4+x^3+x^2+x+1), so the roots can be expressed with only radicals.
(BTW, radicalSolve(x^4+x^3+x^2+x+1,x) also gives sin/cos.) I think for consistency, "radicalSolve" should not give answers with sin/cos (aka cyclotomic roots) when there's radical root available. This can be solved by tweaking "solveInner" in sovlerad.spad. - Qian -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
