This example demonstrates how to use the trigonometric methods of the Math class. You can see the use of method such as Math.sin(), Math.cos(), Math.tan(), etc.
package org.kodejava.example.math;
public class TrigonometricExample {
public static void main(String[] args) {
double radians = 1.0d;
double sine = Math.sin(radians);
double cosine = Math.cos(radians);
double tan = Math.tan(radians);
double asine = Math.asin(sine);
double acosine = Math.acos(cosine);
double atan = Math.atan(tan);
System.out.println("Sine of " + radians + " = " + sine);
System.out.println("Cosine of " + radians + " = " + cosine);
System.out.println("Tangent of " + radians + " = " + tan);
System.out.println("Arcsine of " + sine + " = " + asine);
System.out.println("Arccosine of " + cosine + " = " + acosine);
System.out.println("Arctangent of " + tan + " = " + atan);
}
}
The output of the program are:
Sine of 1.0 = 0.8414709848078965
Cosine of 1.0 = 0.5403023058681398
Tangent of 1.0 = 1.5574077246549023
Arcsine of 0.8414709848078965 = 1.0
Arccosine of 0.5403023058681398 = 1.0
Arctangent of 1.5574077246549023 = 1.0
