Hello, Let mathcal(S) the surface of equation z = ln(x^2y^2) it's the graph of your function f Remark that mathcal(S) is a revolution surface, because f(x,y) = g(r) where r = sqrt(x^2y^2) is the polar radius Actually, g(r) = ln(r^2) = 2 ln(r) So, graph the curve of equation z = 2ln(x) in the xOz plane
