- Variable names in text input fields:
type "t" for .
- Variable names in labels:
"t" represents
(so, for example, "t_{min}" gives the minimum value for
)
-- see "How To Use".
Also, the value =3.14159... is represented
as "Pi."
- The
buttons under the graph allow various manipulations of
the graph coordinates.
- The text input fields for functions can accept
a wide variety of expressions to represent functions.
- There are four input fields which specify
bounds on the variables for the function:
- The variable r (the radius)
takes values between r_{min}
and r_{max}, specified by the fields marked
"r_{min}=" and
"r_{max}=".
- The variable (the angle, measured counterclockwise in
the xy-plane)
takes values between _{min}
and _{max}, with
_{min}
and _{max}
specified by the fields marked
"t_{min}=" and
"t_{max}=".
Note that the value in each text input field is multiplied by
=3.14159...
These four text input fields can accept any decimal number input.

representation.
