Mathematical functions

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)
