Yacas (Yet Another Computer Algebra System) is a small and highly flexible general-purpose Computer Algebra System (CAS). The syntax uses an infix-operator grammar parser. The distribution contains a small library of mathematical functions, but its real strength is in the language in which you can easily write your own symbolic manipulation algorithms. The core engine supports arbitrary precision arithmetic and is able to execute symbolic manipulations on various mathematical objects by following user-defined rules. For detailed information on yacas features and usage, see http://www.yacas.org.
This versatile Computer Algebra System (CAS) was developed to cater to a broad audience, primarily consisting of mathematicians, engineers, and students. It provides a user-friendly platform for performing symbolic mathematical computations, solving intricate equations, all accessible via a command-line interface. Furthermore, it serves as a free alternative to commercial CAS software.
For mathematics enthusiasts (probably less than 1% of the population), this tool offers the capability to conduct advanced mathematical manipulations and solve complex equations, making it valuable for research purposes and even recreational mathematical exploration. On the other hand, students can benefit from its educational potential, using it as an open-source resource to learn and practice mathematics while experiencing the advantages of an open-source product like Yacas.
