Trigonometric Math Functions

 

Angular Math methods

Two Java Math functions are used in accomplishing the conversion process from degree to radians and vice versa.

·      Math.toDegrees converts the given radian value to its degree equivalent value

·      Math.toRadians converts the input degree value to its equivalent radian value

class java {
    public static void main(String args[]) {
        double a=3.14;
        System.out.println("The degree conversion output is");
        System.out.println(Math.toDegrees(a));
        double k=180;
        System.out.println("The radians conversion output is");
        System.out.println(Math.toRadians(k));
    }
} 

Output

Trigonometric Math methods

These Math functions include Math.sin(), Math.cos(), Math.tan() which is used to return sine, cosine and tangent values of the input trigonometric variables. Math.asin(), Math.acos() and Math.atan() functions are used to return Arc sine, Arc cosine and Arc Tangent values of the input double variable.

class java {

    public static void main(String args[]) {

        double a=90;

        double k=Math.toRadians(a);

        System.out.println("The sine output is:");

        System.out.println(Math.sin(k));

        System.out.println("The cosine output is:");

        System.out.println(Math.cos(k));

        System.out.println("The tangent output is:");

        System.out.println(Math.tan(k));

        System.out.println("The arc sine output is:");

        System.out.println(Math.asin(k));

        System.out.println("The arc cosine output is:");

        System.out.println(Math.acos(k));

        System.out.println("The arc tangent output is:");

        System.out.println(Math.atan(k));

    }

 Output

Hyperbolic Math methods

These set of Math functions include Math.sinh(), Math.cosh() and Math.tanh() which return hyperbolic sine, cosine and tangent values respectively.

class java {

    public static void main(String args[]) {

        double a=90;

        double k=Math.toRadians(a);

        System.out.println("The hyperbolic sine output is:");

        System.out.println(Math.sinh(k));

        System.out.println("The hyperbolic cosine output is:");

        System.out.println(Math.cosh(k));

        System.out.println("The hyperbolic tan output is:");

        System.out.println(Math.tanh(k));

    }

}
