In the cylindrical coordinate system, a point P is represented by a tripler, θ, z
, where
r, θ
represents a point in polar coordinates and z is the usual rectangular third coordinate. Thus, to convert from cylindrical to rectangular coordinates, we use the equations
To go from rectangular to cylindrical coordinates, we use the equations
The default assumption is that r is a function of θ and z. As usual, you can plot several surfaces on the same axes by dragging expressions onto a plot.
