Packaging the Function

Function.java

import java.util.*; public class Function { /** * Evaluate the function at the given value of x. * * @x argument of the function. * @return the value of the function at x. */ public double evaluate(double x) { return Math.sin(x); } }

The real-valued function f(x) we like to graph is best wrapped into a class. This allows us later to change the function without modifying the class that draws graphs.

Using inheritance, it is even possible to use other functions without modifying Function. This is handled later in CS2.
