Plot Functions Using Abstract Methods

Assignment 13 – Plot functions using abstract methods

Write an abstract class that draws the diagram for a function. The class is defined as follows:

public abstract class AbstractDrawFunction extends JPanel {
/** Polygon to hold the points */
private Polygon p = new Polygon();
protected AbstractDrawFunction() {
drawFunction();

[Code] ...

Test the class with the following functions:

a.f(x) = x2;
b.f(x) = sin(x);
c.f(x) = cos(x);
d.f(x) = tan(x);
e.f(x) = cos(x) + 5sin(x);
f.f(x) = 5cos(x) + sin(x);
g.f(x) = log(x) + x2;

For each function, create a class that extends the AbstractDrawFunction class and implement the f method. Figure below displays the drawing for the first three functions.
