There are six function types current implemented into Pocket Grapher. They are
described as follows.

User Functions  These functions can be user defined with any number of
parameters

Cartesian  These graphs can either be a y(x) or an x(y) they are graphed on
the Graph tab

Parametric  These graphs are defined by two functions x(t) y(t) they are
graphed on the Graph tab

Polar  These graphs are defined as r(a) they are graphed on the Graph tab

3D Cartesian  These graphs are defined as x(y,z), y(x,z) or z(x,y) they are
drawn on the 3D Graph tab

3D Parametric  These graphs are defined by three functions x(u,v), y(u,v),
z(u,v) they are drawn on the 3D Graph tab
Each of these functions can be created by tapping new next to the coorisponding
function type. You may setup a function in the dialog that is displayed. After
clicking ok you may edit it by tapping the edit button that is then created. In
this dialog you can delete the function and change the graph color. You can
also edit intervals but only for Parametric, Polar, 3D Cartesian, and 3D
Parametric functions.
