Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more.
For example, Maxima solves x^2-r*x-s^2-r*s=0 giving the symbolic results [x=r+s, x=-s].
Maxima can calculate with exact integers and fractions, native floating-point and high-precision big floats.
Maxima has user-friendly front-ends, an on-line manual, plotting commands, and numerical...
