Remarks
Use the Constant class to represent
a Curve with a constant Y-value. It inherits from
Curve and provides specialized
implementation for most methods.
A Constant curve has one parameter: the Y-value.
The ValueAt(Double) method returns the constant value of the curve. SlopeAt(Double) always returns zero. Integral(Double, Double) evaluates the definite integral over a specified interval.
A Constant curve is returned by the GetDerivative() method of the Line class.
