Constructor Detail

LeftHandPlot

public LeftHandPlot(org.dalton.polyfun.Polynomial polynomial,
                    double xLower,
                    double xUpper,
                    int subintervals)

Constructor. Calls the constructor for AbstractRiemann and also sets the plot frame title.

Parameters:

polynomial - The poly to get the area under

xLower - The left border of the interval

xUpper - The right border of the interval

subintervals - The number of slices in the interval

Method Detail

getSubintervalArea

public double getSubintervalArea(double leftBorder,
                                 double rightBorder)

Calculate area of a single slice with Left Hand Rule.

Specified by:

getSubintervalArea in class AbstractRiemann

Parameters:

leftBorder - The x-coordinate of the left border of the getSubintervalArea

rightBorder - The x-coordinate of the right border of the getSubintervalArea

Returns:

the area as a double

drawSlice

public void drawSlice(double leftBorder,
                      double rightBorder)

Plot the slice under the given poly using the Left Hand Rule.

Specified by:

drawSlice in class AbstractRiemann

Parameters:

leftBorder - The left x-coordinate of the slice

rightBorder - The right x-coordinate of the slice
