WebSep 7, 2024 · Newton’s method makes use of the following idea to approximate the solutions of f ( x) = 0. By sketching a graph of f, we can estimate a root of f ( x) = 0. Let’s call this estimate x 0. We then draw the tangent line to f at x 0. If f ′ ( x 0) ≠ 0, this tangent line intersects the x -axis at some point ( x 1, 0).
