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.
