This one is also good...

Quote: Maxima is a system for the manipulation of symbolic and
numerical expressions, including differentiation, integration, Taylor
series, Laplace transforms, ordinary differential equations, systems
of linear equations, polynomials, and sets, lists, vectors, matrices,
and tensors. Maxima yields high precision numeric results by using
exact fractions, arbitrary precision integers, and arbitrarily
precision floating point numbers. Maxima can plot functions and data
in two and three dimensions.

The Maxima source code can be compiled on many systems, including
Windows, Linux, and MacOS X. The source code for all systems and
precompiled binaries for Windows and Linux are available at the
SourceForge file manager.

Maxima is a descendant of Macsyma, the legendary computer algebra
system developed in the late 1960s at the Massachusetts Institute of
Technology. It is the only system based on that effort still publicly
available and with an active user community, thanks to its open source
nature. Macsyma was revolutionary in its day, and many later systems,
such as Maple and Mathematica, were inspired by it.

The Maxima branch of Macsyma was maintained by William Schelter from
1982 until he passed away in 2001. In 1998 he obtained permission to
release the source code under the GNU General Public License (GPL). It
was his efforts and skill which have made the survival of Maxima
possible, and we are very grateful to him for volunteering his time
and expert knowledge to keep the original DOE Macsyma code alive and
well. Since his passing a group of users and developers has formed to
bring Maxima to a wider audience.
