Usage (signatures)

board.create('integral', [domain, f]);

The constructed element covers the area between the curve c and the x-axis within the interval i.

Parameters

Name	Type	Description
`domain`	Array	Array of length 2 containing interval bounds for the integral
`f`	Functiongraph	Function graph to be integrated.

Example

Integral area

var domain = board.create('functiongraph', [(t) => Math.cos(t) * t]);
var integral = board.create('integral', [[-2.0, 2.0], domain]);
