static member GetBackwardDifferentiator : 
        targetFunction : Func<float, float> -> Func<float, float>

targetFunction Func<Double, Double>: A delegate that represents a function of one variable.

Func<Double, Double>
A delegate that represents a function of one variable that represents the numerical derivative of targetFunction

In Visual Basic and C#, you can call this method as an instance method on any object of type Func<Double, Double>. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Backward differences are used for the calculation of the derivative.

targetFunction is null.
