Public Overrides Function SlopeAt ( 
	x As Double
) As Double

public:
virtual double SlopeAt(
	double x
) override

abstract SlopeAt : 
        x : float -> float 
override SlopeAt : 
        x : float -> float 

Parameters

x  Double

A real number.

Return Value

For most values of x, this method returns the slope on the line segment on the interval that contains x. If x is less than the lower bound of the first interval, the value returned is the slope of the line segment on the first interval. If x is greater than the upper bound of the last interval, the value returned is the slope of the line segment on the last interval. If x is equal to the boundary of an interval, and the line segments on either side of the point have different slopes, the result is NaN.
