First launch

Description

From the listing uploaded by “catappult”.

Numerical Analysis 2S is a calculator which provide you different numerical methods with some facilities for learning it. These methods allows to solve problems about one-variable equations, systems of equations and interpolation. The most relevant features of this application are: - Graph of continuous functions. - Friendly keyboard with the most important trigonometric, polynomial, exponential and logarithmic functions. - Finding roots in the functions, see their graphs and tables with their iterations in One Variable Equations Chapter. - Solution of systems of linear equations nxn (n equations, n variables) through matrices. - Animations of direct methods to show the process to solve systems of linear equations. - Get the pivoted matrix in the LU factorization and iterative methods such as Jacobi and Gauss Seidel. - Handles mathematical expressions in matrices with complex numbers (Cholesky factorization). - Plotter of interpolating polynomials that allows to graph the polynomial that passes through given points and observe how the function behaves in said points. - Output of pure mathematical expressions in Interpolation Chapter.

Numerical Methods - Calculator APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Numerical Methods - Calculator APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Unknown. After downloading, check that the file's MD5 is 0649fc6a6397cbafa5471924c9afadcd.
