Add/Modify Polar Function
This dialog is used to add or modify a polar graph function.
Function Definition
These fields describe the mathematical attributes of the
function to be graphed.
R= Enter the function to be graphed here, must be a valid function definition containing only "Theta" variables. The character "X" can be substituted for "Theta" to save on typing. For more information on functions and syntax see: Mathematical Expression Rules.
Examples | Graph Result |
3 | Circle With Radius 3 |
Theta | Spiral |
1-Cos(Theta) | Cardioid |
4*cos(2*Theta) | Four-Leafed Rose |
Lower Bound (Radians) And Upper Bound - Used to restrict the functions lower and upper domain (Theta value). Both bounds are required and must be in; (-10,000Pi <= Theta <= 10,000Pi). The specified bound is always included in the graph. For example, if (lower bound = -Pi/2) and (upper bound = 4Pi) then the plotted domain is (-Pi/2 <= Theta <= 4Pi). Must be a valid constant mathematical expression (in radian graph units).
Properties
These settings determine the visual appearance of the function.
Samples - This setting adjusts the level of accuracy that the function is drawn with. It is the number of function points that will be calculated and draw between the lower and upper bounds.
Color - Opens a dialog to changes the function line color. Current color is displayed in the sample rectangle.
Line Width - Changes the function line width.
