## Functions of the JavaScript Object Math

The following functions are part of every JavaScript virtual machine:

- Math.abs;
- Math.acos;
- Math.asin;
- Math.atan;
- Math.ceil;
- Math.cos;
- Math.exp;
- Math.floor;
- Math.log;
- Math.max;
- Math.min;
- Math.random;
- Math.sin;
- Math.sqrt;
- Math.tan;

JSXGraph expands the set of available mathematical functions. To keep the JavaScript implementations clean, the new mathematical functions are part of the JSXGraph board. That means, initially a board has to be created, for example with the command

```
board = JXG.JSXGraph.initBoard('box', {originX: 250, originY: 250, unitX: 40, unitY: 40});
```

Then, the object *board* contains the following additional mathematical functions:

- board.angle(A, B, C)
- board.rad(A, B, C)
- board.distance(arr1, arr2)
- board.pow(a, b)
- board.round(x, n)
- board.cosh(x)
- board.sinh(x)
- board.D(f)
- board.I(interval,f)
- board.root(f,x)
