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 eye 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 if/)).

(Shown: F = sin (x -|- iy))

Parametric-Surface

Plots a perspective, wireframe

model of a parametrized surface

(F(u,f) =

x( u, v)i -f y(U, v)j + c( ti, tt)k).

(Shown: x(u, v) ~ sin .3.c + \y\
