How should I write this mathematical definition in rhinoscript
so that it works and to be able to see the graph on the Rhino screen?
{(u, v) | 0 ≤ u ≥ 2π, 0 ≤ v ≥ π}
x = sin (v) cos (u)
y = sin (v) sin (u)
z = cos (v)

It is to obtain a geometric shape
from that mathematical formula … but it always gives me an error.
Help
Thanks
