Maxima is one of the most widely used programs for calculating solutions to differential equations (ODEs). Maxima/Windows is a desktop-based mathematical software for calculus and numerical analysis. Maxima is based upon a 1984 version of Macsyma and was developed at Massachusetts Institute of Technology by Frank Pfenning and Larry Weiss. Maxima is an algebraic solver. It has a number of advanced features for solving complex numerical problems, including multiple algorithms. It can solve a wide range of problems involving complex functions and linear systems and is capable of solving partial differential equations, non-linear equations, integral equations, and other algebraic equations that do not involve a multiplicative identity. Maxima is a popular free software for calculating solutions to differential equations. Maxima/Windows is one of the most widely used software applications for solving complex mathematical problems. It is an open source software. The software runs on POSIX platforms like Unix, MacOS, and BSD, as well as on Microsoft Windows and Android operating systems. The Maxima program can be downloaded for free from its official website. The installation process requires only installation of the Windows libraries, and installation of the Java platform. The software was written to run under Microsoft Windows only. The Maxima software can also be used in applications designed for academic use. The software comes with a number of demonstration problems and exercises. Some of these problems are based on work done by Frank Pfenning and Larry Weiss. In addition, the Maxima application also comes with an interactive tutorial, which shows students how to solve algebraic equations using Maxima. This tutorial is also used as a practice in the student's homework assignments and college level exams.
