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). WebSep 7, 2024 · The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists: f ′ (x) = lim h → 0f(x + h) − f(x) h. A function f(x) is said to be differentiable at a if f ′ (a) exists.
