(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

f(x,y) = (x^{3}+y^{3})^(1/3)

Show that f_{y}(0,0) = 1

3. The attempt at a solution

f_{y}=y^{2}/(x^{3}+y^{3})^(2/3)

And...I take the limit of it as x and y goes to zero, which gets me 0/0
