Rectangular Coordinates (3D Graphing, Wireframe)
Graphs functions of the form
f
(
x
,
y
) using 3dimensional rectangular coordinates.

How to Use
Enter a function
f
(
x
,
y
) in the text input field marked "
f
(
x
,
y
)=" (
Example:
f
(
x
,
y
)=5
x
^{2}

y
^{2}
)
Click the "
Graph
" button (this button also refreshes the graph)
Rotate the graph by clicking and dragging the mouse on the graph.
To erase the graph and input field, click the "
Clear
" button
The text input field can accept
a wide variety of expressions
to represent functions, and the
buttons under the graph
allow various manipulations of the graph coordinates.
For another way to view surfaces, try the "
faceted hidden surface
" representation.
Examples
Plane
f
(
x
,
y
)=
x
2
y
Hemisphere
f
(
x
,
y
)=√(25
x
^{2}

y
^{2}
)
Paraboloid
f
(
x
,
y
)=
x
^{2}
+
y
^{2}

Saddle
f
(
x
,
y
)=(
x
^{2}

y
^{2}
)/10
Waves
f
(
x
,
y
)=cos(
x

y
)
Ripples
f
(
x
,
y
)=cos(2sqrt(
x
^{2}
+
y
^{2}
))
Other Notes
Surfaces in three dimensions are represented in "wireframe" form. The "
faceted hidden surface
" representation allows for more than one surface to be drawn.
