Class Detail
Integral(i,c)
The Integral element is used to visualize the area under a given curve over a given interval and to calculate the area's value. For that a polygon and gliders are used. The polygon displays the area, the gliders are used to change the interval dynamically.
Parameters:
{Array_JXG.Curve} i,c
The constructed element covers the area between the curve c and the x-axis within the interval i.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
var c1 = board.create('functiongraph', [function (t) { return Math.cos(t)*t; }]);
var i1 = board.create('integral', [[-2.0, 2.0], c1]);
