The second way to graph in 3D is with cylindrical coordinates. We
typically think of r as a function of theta and z. The
Cylindrical Grapher applet asks for a maximum value for r and for
a zWindow to give a viewing window. The user may define two
functions r1 and r2
to graph. The user can scroll theta0 and z0 through the range for
theta and z. The grapher gives the surface along with a point
corresponding to
the graph of (theta0,z0) and curves through that point with one
variable
This applet was designed as by modifying an applet from a demo by
