Xcas calculates fractions without common denominator. Xcas can solve equation, calculate derivative, antiderivative and more. Xcas is a user interface to Giac, which is an open source computer algebra system (CAS) for Windows, macOS and Linux among many other platforms. Giac can be used directly inside software written in C++. Xcas has compatibility modes with many popular algebra systems like WolframAlpha, Mathematica, Maple, or MuPAD. Users can use Giac/Xcas to develop formal algorithms or use it in other software. Giac is used in SageMath for calculus operations. Among other things, Xcas can solve equations (Figure 3) and differential equations (Figure 4) and draw graphs. There is a forum for questions about Xcas. Produce mixed fractions: propfrac(42/15) gives 2 + 4 / 5.Ĭalculate antiderivative of functions (Figure 2).calculate differential (or derivative) of functions (Figure 2).solve differential equations (Figure 3).solve equations even with complex roots (Figure 2).regression (exponential, linear, logarithmic, logistic, polynomial, power).Xcas has the ability of a scientific calculator that provides show input and writes pretty print.Here is a brief overview of what Xcas is able to do: ĬmathOOoCAS, an plugin which allows formal calculation in Calc spreadsheet and Writer word processing, uses Giac to perform calculations.
