Graphical User Interface for Solving Non-Linear Equations for Undergraduate Students

Abstract

Solving non-linear equations problems for root-finding is more challenging rather than linear equations problems. Generally, this is because it cannot be solved by using the standard formula. The numerical method is one of the ways that can be applied, consisting of an iterative procedure. A simulator named Root Calculator to Solve Non-Linear Equations was developed, where it is a graphical user interface (GUI) system that can be used to approximate the root based on the equation and interval given. Four methods were chosen which are the Graphical Method, the Bisection Method, Newton’s Method, and the Secant Method to produce the approximation root. App Designer in MATLAB R2020b software was used for this development.
