Program: How to calculate trigonometric tangent of an angle in java?


Description:

Math.tan() method returns the trigonometric tangent value of an angle.


Code:
package com.java2novice.math;

public class MyTanEx {

	public static void main(String a[]){
		
		System.out.println("Value of tan(90) is: "+Math.tan(90));
		System.out.println("Value of tan(45) is: "+Math.tan(45));
		System.out.println("Value of tan(30) is: "+Math.tan(30));
	}
}

Output:
Value of tan(90) is: -1.995200412208242
Value of tan(45) is: 1.6197751905438615
Value of tan(30) is: -6.405331196646276
