It is easy and fun to draw graphs of curves with the Java graphics library. Simply draw 100 line segments joining the points (x, f(x)) and (x + d, f(x + d)), where x ranges from xmin to xmax and d = (xmax ? xmin)/100. Draw the curve f(x) = 0.00005x3 ? 0.03x2 + 4x + 200, where x ranges from 0 to 400 in this fashion.
Use the following class as your main class:
import javax.swing.JFrame;
/** Test driver class. */
public class CubicCurveViewer
{
public static void main(String[] args)
{
JFrame frame = new JFrame();
final int FRAME_WIDTH = 400;
final int FRAME_HEIGHT = 400;
frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);
frame.setTitle("CubicCurveViewer");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
CubicCurveComponent component = new CubicCurveComponent(0.00005, -0.03, 4, 200);
frame.add(component); frame.setVisible(true); } }
You need to supply the following class in your solution: CubicCurveComponent
