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.

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:
