C#
public override double Integral(
	double lowerBound,
	double upperBound
)

Parameters

lowerBound  Double
The lower bound of the integration interval.
upperBound  Double
The upper bound of the integration interval.

Return Value

Double
The definite integral of the curve between lowerBound and upperBound.

Remarks

The integral of a spline curve is computed exactly.

The most reliable way to integrate a function that is defined in terms of tabulated data is to fit a spline curve through the data points, and approximate the integral of the function by the integral of the spline.
