Public Shared Function FindZero ( 
	targetFunction As Expression(Of Func(Of Double, Double)),
	initialGuess As Double
) As Double

C++/CLI

public:
static double FindZero(
	Expression<Func<double, double>^>^ targetFunction, 
	double initialGuess
)

static member FindZero : 
        targetFunction : Expression<Func<float, float>> * 
        initialGuess : float -> float

targetFunction Expression<Func<Double, Double>>: A lambda expression that represents a function of one variable that specifies the function on the left-hand side of the equation.
initialGuess Double: An initial guess for ther zero.

Double
The best approximation to a zero of targetFunction.

Use this method when you have very little information about the location of the zero.
