Cant method requires more iterates than the New-ton method. But note that the secant method does not require a knowledge of f0(x), whereas Newton’s method requires both f(x)andf0(x). Note also that the secant method can be considered an approximation of the Newton method xn+1 = xn− f(xn) f0(xn) by using the approximation f0(xn) ≈ f(xn.
