Its most important task in numerical analysis to find roots of nonlinear equations, several methods already exist in literature to find roots but in this paper, we introduce a unique idea by using the interpolation technique. The proposed method derived from the newton backward interpolation technique and the convergence of the proposed method is quadratic, all types of problems (taken from literature) have been solved by this method and compared their results with another existing method (bisection method (BM), regula falsi method (RFM), secant method (SM) and newton raphson method (NRM)) it’s observed that the proposed method have fast convergence. MATLAB/C++ software is used to solve problems by different methods.

In this article, an iterative, bracketing and derivative-free method have been proposed with the second-order of convergence for the solution of non-linear equations. The proposed method derives from the Stirling interpolation technique, Stirling interpolation technique is the process of using points with known values or sample points to estimate values at unknown points or polynomials. All types of problems (taken from literature) have been tested by the proposed method and compared with existing methods (regula falsi method, secant method and newton raphson method) and it’s noted that the proposed method is more rapidly converges as compared to all other existing methods. All problems were solved by using MATLAB Version: 8.3.0.532 (R2014a) on my personal computer with specification Intel(R) Core (TM) i3-4010U CPU @ 1.70GHz with RAM 4.00GB and Operating System: Microsoft Windows 10 Enterprise Version 10.0, 64-Bit Server, x64-based processor.

In numerical analysis, methods for finding roots play a pivotal role in the field of many real and practical applications. The efficiency of numerical methods depends upon the convergence rate (how fast the particular method converges). The objective of this study is to compare the Bisection method, Newton-Raphson method, and False Position Method with their limitations and also analyze them to know which of them is more preferred. Limitations of these methods have allowed presenting the latest research in the area of iterative processes for solving non-linear equations. This paper analyzes the field of iterative methods which are developed in recent years with their future scope.

The main purpose of this paper is to obtain the real roots of an expression using the Numerical method, bisection method, Newton's method and secant method. Root analysis is calculated using specific, precise starting points and numerical methods and is represented by Maple. In this research, we used Maple software to analyze the roots of nonlinear equations by special methods, and by showing geometric diagrams, we examined the relevant examples. In this process, the Newton-Raphson method, the algorithm for root access, is fully illustrated by Maple. Also, the secant method and the bisection method were demonstrated by Maple by solving examples and drawing graphs related to each method.

In this paper the investigation of the axisymmetric flow of a liquid with a boundary perpendicular to the flow is considered. Analytical equations are derived for the radial and axial velocity and pressure components of fluid flow in a pipe of finite length with a movable right boundary, and boundary conditions on the moving boundary are also defined. A numerical solution of the problem on a finite-difference grid by the iterative Newton-Raphson method for various velocities of the boundary motion is obtained.

Abstrak  Telah dilakukan penelitian tentang distribusi intensitas cahaya pada fenomena difraksi celah tunggal dengan tujuan menerapkan metode Bagi Dua dan metode Newton Raphson untuk memperoleh solusi jarak antara dua titik intensitas dalam fenomena difraksi celah tunggal, menetukan jarak antara dua intensitas pada pita terang, memperoleh grafik distribusi intensitas cahaya terhadap jarak pada kasus difraksi cahaya Franhoufer celah tunggal, serta membandingkan kekonvergenan metode Bagi Dua dan metode Newton Raphson. Solusi jarak antara dua intensitas pada pita terang pada kasus difraksi cahaya Franhoufer celah tunggal diperoleh dengan mencari akar-akar persamaan intensitas cahayanya. Hasil penelitian menunjukan jarak yang semakin besar ketika intensitasnya makin kecil. Ada tiga puncak intensitas, yang pertama puncak untuk intensitas maksimum pada terang pusat yang berada pada jarak 0 cm dan dua puncak untuk terang pertama setelah terang pusat yang mana intensitasnya tinggal 0.05I0 dan berada pada jarak 0.154875 cm sebelah kiri dan sebelah kanan dari intensitas maksimum. Grafik antara jarak dengan perbandingan intensitas terhadap terang maksimum berbentuk sinusoidal, terdapat tiga puncak intensitas. Puncak pertama menunjukan intensitas maksimum yang terdapat pada pita terang pusat dan dua puncak dengan intensitas 0.05I0  yang berada pita terang pertama. Pada kasus ini diperoleh hasil bahwa metode Newton Raphson lebih cepat konvergen dari metode Bagi Dua karena hanya memerlukan 4 iterasi untuk memperoleh solusi, sedangkan metode Bagi Dua membutuhkan 20 iterasi. Metode Newton Raphson juga memiliki nilai error pendekatan lebih kecil dari metode Bagi Dua yaitu 6.43929 x 10-13 sampai 7.52642 x 10-7 sedangkan metode Bagi Dua 1.90735 x 10-6. Abstract  Research on the distribution of light intensity in the phenomenon of single slit diffraction has been carried out with the aim of applying the Bisection method and the Newton Raphson method to obtain a solution between two points in a single slit diffraction phenomenon, determining the distance between two point of intensity in the bright band, obtaining a graph of the light intensity distribution to distance in the case of Franhoufer single slit light diffraction, and comparing the speed of convergence of the Bisection method and the Newton Raphson method. The solution of the distance between two intensities in the bright band in the case of Franhoufer light diffraction in a single slit obtained by looking for the roots of the light intensity equation. The results of the study show that the greater the distance when then intensity gets smaller. There are three peak intensities, the first peak for the highest intensity in the central bright band which is located at a distance of 0 cm and two peaks in the first bright with the intensity is 0.05I0 and is 0.154875 cm left and right of the maximum intensity. The graph between the distance and intensity ratio is sinusoidal, which is three peak intensities. The first peak shows the highest intensity in the central bright band and the two peaks with the intensity of 0.05I0 which is the first bright band. In this case the results of the Newton Raphson method are converged faster than the method of Bisection because it only requires 4 iterations to obtain a solution, while the Bisection method requires 20 iterations. The Newton Raphson method also has a smaller error value than the Bisection method, which is 6.43929 x 10-13 to 7.52642 x 10-6 when the Bisection method is 1.90735 x 10-6.

The theory of quadratic equations (with real coefficients) is an important topic in the secondary school mathematics curriculum. Usually students are taught to solve a quadratic equation ax2 + bx + c = 0 (a ≠ 0) algebraically (by factorisation, completing the square, quadratic formula), graphically (by plotting the graph of the quadratic polynomial y = ax2 + bx + c to find the x-intercepts, if any), and numerically (by the bisection method or Newton-Raphson method). Less well-known is that we can indeed solve a quadratic equation geometrically (by geometric construction tools such as a ruler and compasses, R&C for short). In this article we describe this approach. A more comprehensive discussion on geometric approaches to quadratic equations can be found in [1]. We have also gained much insight from [2] to develop our methods. The tool we use is a set square rather than the more common R&C. But the methods to be presented here can also be carried out with R&C. We choose a set square because it is more convenient (one tool is used instead of two).

In this work, the concept of resonant states (RSs) in a finite square quantum well is presented. We first derive the analytic secular transcendental equations for even and odd states by applying the outgoing wave boundary conditions into the one-dimensional Schrödinger’s wave equation. The complex solution of these equations is found using the numerical Newton-Raphson method implemented in MATLAB. We can see in particular, that the RSs present a general class of Eigenstates, which includes bound states, anti-bound states, and normal RSs.
