Constructor Detail

TSEModel

public TSEModel()

Create a new model with default values. The default function is sin(x), the default point is x = 0 and the number of terms is 2.

Method Detail

getFunction

public java.lang.String getFunction()

Returns:

the function in use.

setFunction

public boolean setFunction(java.lang.String function)

Set the function to use.

Returns:

true if the function was accepted, false if the function cannot be used or the requested number of terms was too high for this function.

getPoint

public double getPoint()

Returns:

the point used for Taylor series expansion.

setPoint

public void setPoint(double point)

Set the point to use for Taylor series expansion.

getNumberOfTerms

public int getNumberOfTerms()

Returns:

the number of terms in the Taylor series.

setNumberOfTerms

public boolean setNumberOfTerms(int terms)

Set the number of terms in the Taylor series.

Returns:

whether the program can handle this many terms for the current function.

getSeriesCoeff

public double getSeriesCoeff(int n)

Returns:

the coefficient of xⁿ in the taylor series expansion.

getLastChange

public taylor.Change getLastChange()

Returns:

the last change in the model.

isLoading

public boolean isLoading()

Returns:

whether the model is between states. If true, trying to get the state of the model will cause delays.

getError

public java.lang.String getError()

Returns:

the last error that occurred.

evaluateFunction

public double evaluateFunction(double x)

Returns:

the function evaluated in the given point x.

evaluateSeries

public double evaluateSeries(double x)

Returns:

the Taylor series evaluated in the given point x.

addChangeListener

public void addChangeListener(javax.swing.event.ChangeListener l)

Add a ChangeListener.

removeChangeListener

public void removeChangeListener(javax.swing.event.ChangeListener l)

Remove a ChangeListener.

fireStateChanged

public void fireStateChanged(javax.swing.event.ChangeEvent e)

Notify all ChangeListeners.
