Piecewise 3D function
asterisco500 shared this question 2 years ago
I'm trying to graph this function
f(x,y) = 0 if y=-x^2 and f(x,y) = 2xy/(x^2+y^2) otherwise
I tried to use the If command this way
f(x,y) = If( y=-x^(2), 0, (2xy)/(x^(2)+y^(2)) )
But it didn't work. Is there a way to graph the function?
