WebAug 6, 2015 · Now, let's take a look at the equation $z^2 = x^2 + y^2 -1$. We observe that it must hold $x^2+y^2 \ge 1$, since $z^2$ is always non - negative. Web3 Surfaces in Three-Space The graph of a 3-variable equation which can be written in the form F(x,y,z) = 0 or sometimes z = f(x,y) (if you can solve for z) is a surface in 3D. One technique for graphing them is to graph cross-sections (intersections of the surface with well-chosen planes) and/or traces pop out camper bed
