# Java Math sin() Method ## Java Math Class

Java Math class provides several methods to perform several operations on math calculations like max(), min(), sin(), cos(), round(), ceil(), floor(), abs() etc.
The java.lang.Math class contains various methods for performing basic numeric operations

Here, in the page we will discuss about the math sin() Method in java.

## Java Math sin() Method :

This function returns the trigonometric sine of an angle.

### Special Points :

• If the argument is NaN or an infinity, then the result is NaN.
• If the argument is zero, then the result is a zero with the same sign as the argument.

### Syntax  :

`public static double sin(double a)`

### Example 1 :

Run
```public class Main{
public static void main(String[] args) {
double sine = Math.sin(angle); // calculate sine of angle
System.out.println("Sine of 30 degrees: " + sine);
}
}

```

### Output :

```Sine of 30 degrees: 0.49999999999999994
```

### Example 2  :

Run
```import java.lang.Math;
public class Main {
public static void main(String[] args)
{

double positiveInfinity = Double.POSITIVE_INFINITY;
double negativeInfinity = Double.NEGATIVE_INFINITY;
double nan = Double.NaN;
double result;
result = Math.sin(negativeInfinity);
System.out.println(result);
result = Math.sin(positiveInfinity);
System.out.println(result);
result = Math.sin(nan);
System.out.println(result);
}
}
```

```NaN
NaN
NaN
```
