## Description

Advanced Trigonometry Calculator is an open source calculator created in its entirety yet by Renato Alexandre dos Santos Freitas. In it you can find a calculator made firstly to solve trigonometric calculations but throughout its development acquired new functions beyond the trigonometric. Capacities such as the introduction and response in four different numerical systems, the introduction and response in SI prefixes, the commands to force the trigonometric calculation mode, the creation and use of variables, the easy use of previous results, the introduction of multiple expressions and the capacity to solve equations systems with complex numbers make this application stands out for its large capacities and its cost to the user.
