Advanced Polynomial Calculator

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 or sent to various Internet options( Skype, Viber, e-mail).The the app has function to show the meaning of the polynomial in points and showing graph of roots i complex plan
