The Secant Method is basically a way of replacing the second derivative of a function with an approximation. So. f ″ ( x) ≈ f ′ ( x 2) − f ′ ( x 1) x 2 − x 1. We then use this in Newton's formula. x k + 1 = x k − f ′ ( x k) f ″ ( x k) It turns out that the secant method converges with rate equal to the golden ratio.
