Parameters

f  OneVariableFunction
The function.
df  OneVariableFunction
The derivative of f.
lower  Double
The lower limit.
upper  Double
The upper limit.

Return Value

Double

Remarks
Iteration stops when either the estimated error is less than the tolerance, or the maximum number of iterations is reached. Setting the error tolerance to less than zero ensures that the maximum number of iterations is always reached.
