I couldn't find any resources in my book or online dedicated to this subject. I honestly don't even know where to begin for this problem.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

Let [itex] f(x,y) = 4 / (1+ x^2 + y^2) [/itex] and let S be the surface given by the graph of f(x,y)

b) Let C2 denote the curve in the xy-plane given by [itex] r(t)= t, 3/2 − t^2[/itex] and let C denote the curve on the surface S which has C2 as its shadow in the xy-plane. Find the parametric equations r = r(t) for C

2. Relevant equations

3. The attempt at a solution
