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.
var c1 = board.create('functiongraph', [function (t) { return t*t*t; }]);
var i1 = board.create('integral', [[-1.0, 4.0], c1]);

				
				
				
				
					
						
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.
Field Detail
{JXG.Point} baseLeft
The point on the axis initially corresponding to the lower value of the interval.

{JXG.Point} baseRight
The point on the axis initially corresponding to the higher value of the interval.

{Glider} curveLeft
The glider on the curve corresponding to the lower value of the interval.

{Glider} curveRight
The glider on the axis corresponding to the higher value of the interval.
