“…Examples complement the theory. Due to its generality, this article's technique can be applied on other method with inverses along the same lines [6,14,19,32,39,43,[45][46][47][48][49]. It is worth noting that the method (8) should be used for sufficiently small m. Otherwise, if m is very large, it may be as expensive to implement as method (4).…”

“…Table 5 demonstrates that the convergence of the proposed methods closely corresponds with the convergence of Newton's method, particularly for values of k ranging from 4 to 5 with the convergence order closely approximating 2. Then, the definition of the derivative according to Fréchet [1,8,11,27,30] is given for the mapping F F ′ (a) =   1 0 0 0 e a 2 0 0 0 (e − 1)a 3 + 1   .…”

“…The conditions of the Theorem 3 hold provided that ℓ 0 = e − 1, k = 1, a = a(t) = ℓ 0 t. Then, we can have ρ ∈ (0, 0.2909883534). Then, the definition of the derivative according to Fréchet [1,8,11,27,30] is given below for the operator E E ′ (z(w))(ξ) = w(ξ) − 18 1 0 ξτz(τ) 2 w(τ)dτ for each w ∈ K[0, 1]. Therefore, the conditions are validated, since for x * = 0, E ′ (x * (ξ)) = I provided that ℓ 0 = 9, a = a(t) = ℓ 0 t, and k = 1.…”

“…They are especially important in chaos theory and complexity, where they can model systems with great sensitivity to initial conditions, e.g., in meteorology, population dynamics, and in the financial sector [9,10]. According to Abel's impossibility theorem [11], there is no algebraic solution to polynomials of degree greater than four expressed in terms of a finite number of additions, subtractions, multiplications, divisions, and root extractions; thus, we need to turn to numerical iterative methods such as Newton's method and fixed-point iteration [12][13][14] to approximate the roots of a general Equation (1) one at a time. Single root finding methods are highly sensitive to the initial guess values used, though, and their local convergence behavior diverges as f ′ (x) approaches zero.…”
