Plot Type and Description Example
Wii'eframe
Plots a perspective, wireframe
view of tlie surface determined by
a function of two variables.
(Shown: F = — 4 . / ’ ] / + y ^ )
HP 48 Plot Types (continued)
Pseudo-Contour
For a function. F { x , y ) , plots a
lattice of line segments that are
each tangent to a contour of the
function (a curve satisfying
{/(^constant). This allows
your
e y e
to pick out tlie contours
without actually plotting them.
(Shown: F = (,r" — l)/(j/' ^1))
Y-SUce
Plots a. series of cross-sections of
the surface determined by the
current function of two variables
and can create an animation of
them to help you visualize a
moving slice through the surface.

Gridmap
Plots a rectilinear grid as it is
“distorted” under the mapping of
a complex-valued function
{ F ( x -h i f / ) ) .
(Shown: F = sin ( x -|- i y ) )
Parametric-Surface
Plots a perspective, wireframe
model of a parametrized surface
( F ( u , f ) =
x ( u , v ) i
