Cylindrical Coordinates (3-D Graphing, Wireframe)
Graphs one function of the form z
using cylindrical coordinates in three dimensions.

How to use
The text input fields for functions can accept
a wide variety of expressions to represent functions, and the
buttons under the graph allow various manipulations of
the graph coordinates.
- Enter a function f (r,θ)
in the text input field
marked "f (r,θ)="
Note: Type "t" for θ in the text
- 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 all input fields, click the
- There are four input fields which specify
bounds on the variables for the function:
- The variable r (the radius)
takes values between rmin
and rmax, specified by the fields marked
- The variable θ (the angle, measured counterclockwise
in the xy-plane)
takes values between θmin*&pi
and θmax*π, with
θmin and θmax
specified by the fields marked
- These four text input fields can accept any decimal number input.
For another way to view surfaces, try the
"faceted hidden surface" representation.

The "faceted hidden surface" representation
allows for more than one surface to be drawn.
