The basics of computer algebra and the language of Mathematica
are described. This title will lead toward an understanding of Mathematica
that allows the reader to solve problems in physics, mathematics, and chemistry. Mathematica
is the most widely used system for doing mathematical calculations by computer, including symbolic and numeric calculations and graphics. It is used in physics and other branches of science, in mathematics, education and many other areas. Many important results in physics would never be obtained without a wide use of computer algebra.
