Parametric Surfaces (3-D Graphing, Wireframe)

Graphs a surface in three dimensions specified parametrically, as x=f (s,t), y=g (s,t), and z=h (s,t), with parameters s and t

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.
For another way to view surfaces, try the "faceted hidden surface" representation.
f (s,t)=5 cos t sin s
g (s,t)=5 sin t sin s
h (s,t)=5 cos s
f (s,t)=s
g (s,t)=t
h (s,t)=s+t
f (s,t)=5 cos t
g (s,t)=5 sin t
h (s,t)=s
Slant Cylinder:
f (s,t)=s+5 cos t
g (s,t)=5 sin t
h (s,t)=s

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.
