explicit isomorphism from a curve of genre zero to the Riemann sphere

explicit isomorphism from a curve of genre zero to the Riemann sphere [closed]

i can't figure out this exercise: i have this singular curve in $\mathbb{P}^2\mathbb{C}$: $X^2Y^2+Y^2Z^2+X^2Z^2=0$, i have shown that its desingularization is a curve of genre zero, but now i must find an explicit isomorphism with the Riemann sphere and i don't know how to do it.

In the same scenario as your previous question, this is not appropriate for this forum: try math.stackexchange.com – Chris Gerig Jan 24 2012 at 18:24

and presumably by genre, you mean genus – Yemon Choi Jan 24 2012 at 18:40
