Method	Description
Derivative ( double x ) : double	Calculates function derivative. The method calculates function derivative at point x.
Derivative2 ( double y ) : double	Calculates function derivative. The method calculates the same derivative value as the Derivative method, but it takes not the input x value itself, but the function value, which was calculated previously with the help of Function method. Some applications require as function value, as derivative value, so they can save the amount of calculations using this method to calculate derivative.
Function ( double x ) : double	Calculates function value. The method calculates function value at point x.
LinearFunction ( ) : System	Initializes a new instance of the LinearFunction class.
LinearFunction ( DoubleRange range ) : System	Initializes a new instance of the LinearFunction class.
LinearFunction ( double alpha ) : System	Initializes a new instance of the LinearFunction class.
LinearFunction ( double alpha, DoubleRange range ) : System	Initializes a new instance of the LinearFunction class.

Method Details

Derivative() public method

Calculates function derivative.

The method calculates function derivative at point x.

public Derivative ( double x ) : double
x	double	Function input value.
return	double

Derivative2() public method

Calculates function derivative.

The method calculates the same derivative value as the Derivative method, but it takes not the input x value itself, but the function value, which was calculated previously with the help of Function method.

Some applications require as function value, as derivative value, so they can save the amount of calculations using this method to calculate derivative.

public Derivative2 ( double y ) : double
y	double	Function output value - the value, which was obtained /// with the help of method.
return	double
