Methods

o getPoint 
public abstract EDU.emporia.mathtools.Point2D getPoint(double u) throws Graphable_error
Returns the point that corresponds to the parameter

Parameters:
u - The parameter
Returns:
The point occurring at the parameter
Throws: Graphable_error
o getPoints 
public abstract EDU.emporia.mathtools.Point2D[] getPoints(double uMin,
                                                          double uMax,
                                                          int numberOfPoints) throws Graphable_error
Returns an array of points that can be used in constructing a graph.

Parameters:
uMin - The lowest parameter for constructing the array.
uMax - The highest parameter for constructing the array
numberOfPoints - The number of points in the array
Returns:
An array of points on the graph corresponding to equally spaced parameters
Throws: Graphable_error
o getPoints 
public abstract EDU.emporia.mathtools.Point2D[] getPoints(double uMin,
                                                          double uMax,
                                                          double delta) throws Graphable_error
Returns and array of points that can be used in graphing the curve

Parameters:
uMin - The lowest parameter used to construct the array
uMax - The highest parameter used to construct the array
Returns:
An array of points constructing using parameters between uMin and uMax spaced delta units apart
Throws: Graphable_error
o getTitle 
public abstract java.lang.String getTitle()
Provides a title for the Graphable object that will be displayed on the coordinate system when it is selected.

Returns:
The title for the Graphable object.
