Description
Wireframe
Plots
a
perspective,
wireframe
view
of
the
surface
determined
by
a
function
of
two
variables.
(Shown:
F
=
z*
—
4z?y?
+
y*)
Pseudo-Contour
For
a
function,
F(z,
y),
plots
a
lattice
of
line
segments
that
are
each
tangent
to
a
contour
of
the
function
(a
curve
satisfying
F(x,y)=constant).
This
allows
your
eye
to
pick
out
the
contours
without
actually
plotting
them.
(Shown:
F
=
(2%
—1)/(y*
=
1))
Y-Slice
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.
(Shown:
F
=
z*
—
4z?y?
+
y*)
Gridmap
Plots
a
rectilinear
grid
as
it
is
“distorted”
under
the
mapping
of
a
complex-valued
function
(F(x
+iy).
(Shown:
F'
=
sin
(xz
+1y))
Parametric-Surface
Plots
a
perspective,
wireframe
model
of
a
parametrized
surface
(F(u,v)
=
z(u,v)i+
y(u,v)j
+
z(u,
v)k).
(Shown:
z(u,v)
=
sin
3z
+
$y;
y(u,v)
=
+y;
z(u,v)
=
cos
3x.)
