public class TangentLine
extends DrawGeometric

A Tangent line is a line that is tangent to the graph of a specified function of one argument at a specified value of its argument. If added to a CoordinateRect, it will appear as a line. A TangentLine is a Computable object, so should be added to a Controller to be recomputed when the Value or Function changes.

Constructor Detail

TangentLine

public TangentLine(Value x,
                   Function f)

Create a tangent line to the graph of a function.

Parameters:

x - The x-coordinate where the tangent is drawn.

f - The line is tangent to the graph of this function. This should be a function of one variable.
