复数的n次根 by daniel.f.mansfield

GeoGebra 命令及参数

1. Angle(A, O, α) → θ
2. If(y(α) > 0, θ, (-θ)) → arga
3. Segment(α, O) → a
4. Segment(A, O) → b
5. Sequence((r * (cos((arga + ((2 * π) * k)) / n) + (ί * sin((arga + ((2 * π) * k)) / n)))), k, ceil(((-n)) / 2), floor(n / 2)) → theroots
6. Polygon(theroots) → poly1
7. Sequence((θ + ((2 * π) * k)) / n, k, ceil(((-n)) / 2), floor(n / 2)) → theargs
