WebSep 19, 2014 · Cylindrical Coordinates in Matlab. ... Setting `z=0` in `z=sqrt(x^2+y^2)` yields `0=sqrt(x^2+y^2)`, or equivalently, `0=x^2+y^2`, whose graph is the single point `(0,0)`. Thus, the trace in the `xy`-plane is the point `(0,0)`. To flesh out the rest of the surface, we take parallel cross sections for various values of `z`. WebCylindrical coordinates are really just an extension of polar coordinates. For points in the -plane, we describe them using and , where is the distance from the origin and is the angle with the positive -axis. We then append a -coordinate, which tells us the vertical displacement of the point.
