Computer Algebra Systems

A Computer Algebra System (CAS) is a software tool that performs symbolic mathematics, enabling users to manipulate mathematical expressions exactly rather than approximately. It can solve equations, simplify expressions, factor polynomials, compute derivatives and integrals, and perform algebraic transformations, all automatically. Unlike regular calculators that provide numerical results, CAS handles symbols and formulas, making it valuable for both education and research. Examples include Wolfram Mathematica, Maple, and SageMath. These systems help mathematicians, scientists, and engineers analyze complex problems efficiently and accurately, facilitating deeper understanding and discovery in various mathematical domains.
