Element Detail
Integral
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.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "integral".
- Possible parent array combinations are:
-
{Array} i
{JXG.Curve} 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 t*t*t; }]);
var i1 = board.create('integral', [[-1.0, 4.0], c1]);
