## Can you use cosine in Java?

Syntax of a Java cos Function

cos(double number); Number: It can be a number or a valid numerical expression for which you want to find Cosine value. If the number argument is a positive or negative number, the Java Math. cos function will return the Cosine value.

## Can Java do trig?

The java. lang. Math class contains methods for trigonometric operations like cos(), sin(), tan(), tanh(), cosh(), atan(), etc.

## How do you use Arccos in Java?

acos(double a) returns the arc cosine of an angle, in the range of 0.0 through pi. If the argument is NaN or its absolute value is greater than 1, then the result is NaN.

## How do you square 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 get pi in Java?

To make the code easier to follow, we’ll set the radius and length as constants, like this:

1. import java. lang. Math. *;
2. public class Pie {
3. public static void main(String[] args) {
6. double len = 15;
7. // calculate the area using PI.

## What is atan2 in Java?

atan2() is an inbuilt method in Java that is used to return the theta component from the polar coordinate. The atan2() method returns a numeric value between – and representing the angle. of a (x, y) point and the positive x-axis.

## What is toRadians in Java?

toRadians() is used to convert an angle measured in degrees to an approximately equivalent angle measured in radians.

## What is asin () method?

Math. asin() returns the arc sine of an angle in between -pi/2 and pi/2. Arc sine is also called as an inverse of a sine. If the argument is NaN or its absolute value is greater than 1, then the result is NaN. If the argument is zero, then the result is a zero with the same sign as the argument.

## How do you use Arctan in Java?

Math. atan() returns the arc tangent of an angle in between -pi/2 through pi/2. If the argument is NaN, then the result is NaN. Note:If the argument is zero, then the result is a zero with the same sign as the argument.
