About this app

The application is used to numerically find approximations to the roots of a polynomial. The implementation applies the Newton method and as second Durand-Kerner-Weierstrass method to determine approximations to the roots of a polynomial with real coefficients. The application stores and processes the data of many polynomials into a database, as opposed to BasePolynomial_Calculator application designed to store and process the data of one polynomial.
The app stores the data in a database of type SQLit. The application has localization in Bulgarian and English
The app has function “Export data for print” writes data from a list of full numerical approximations and rounded approximations of the roots in a polynomialEquationRoots.txt file and display a dialog for choosing a storage option locally in Phonstorage on the device where the application is appended .
The the app has function to show the meaning of the polynomial in points and showing graph of roots i complex plan
