How do you do 2 squared in Java?

Squaring a number in Java can be accomplished in two ways. One is by multiplying the number by itself. The other is by using the Math. pow() function, which takes two parameters: the number being modified and the power by which you’re raising it.

How do you write Cos X in Java?

Example 1

public class CosExample1.
{
public static void main(String[] args)
{
double a = 60;
// converting values to radians.
double b = Math.toRadians(a);
System.out.println(Math.cos(b));

How do you do sin squared in Java?

sin^2(value) in maths is equal to Java Math. sin(value) * Math. sin(value), which can be simplified by making Math. sin(value) a variable and use it instead of computing the sin two times.

How do you do cos in Java?

Syntax of a Java cos Function cos in Java Programming language is as shown below. static double cos(double number); //Return Type is Double // In order to use in program: Math. cos(double number); Number: It can be a number or a valid numerical expression for which you want to find Cosine value.

Is Java math Cos degrees?

Java Math cos() method example The cos(double a) returns the cosine of the method argument value. It must be noted that the parameter is in radians, however if your source value is degree which is always the case for real world applications the handy Math. toRadians() method will be helpful on the conversion.

How do you use math sqrt in Java?

Syntax

public static double sqrt(double number);
int X = 9; double R = Math.sqrt(X); System.out.println(“The square root of ” + X + ” is ” + R); // The square root of 9 is 3.0.
int X = 9; double R = Math.pow(X, 0.5); System.out.println(“The square root of ” + X + ” is ” + R); // The square root of 9 is 3.0.

Can you use trig functions in Java?

public class PowerFunc1 {
public static void main(String[] args)
{
double a = 5;
double b = 2;
System. out. println(Math. pow(a, b)); // return a^b i.e. 5^2.
}

How do you raise to a power in Java?

Math. pow(double a, double b) returns the value of a raised to the power of b . It’s a static method on Math class, which means you don’t have to instantiate a Math instance to call it. The power of a number is the number of times the number is multiplied by itself.
