You need to compute sine, cosine, and other trigonometric functions.
Use the trig functions in
java.lang.Math.random( ), all the methods of the
Math class are
static, so no
Math instance is necessary. This
makes sense, as none of these computations maintains any state. Here
is a program that computes a few trigonometric values and displays
the values of
PI that are available in the math library:
// Trig.java System.out.println("Java's PI is " + Math.PI); System.out.println("Java's e is " + Math.E); System.out.println("The cosine of 1.1418 is " + Math.cos(1.1418));
Java 1.3 (Java 2 JDK 1.3) includes a new class,
, which is intended to perform most of
the same operations with greater cross-platform repeatability.
