A lambda expression that represents a function of one variable.
A delegate that represents a function of one variable that
represents the numerical derivative of
The derivative is calculated symbolically from the supplied lambda expression.
The expression must not contain loops or blocks. If functions are encountered for
which no symbolic derivative is available, a numerical approximation is used.
