Cymath vs PARI/GP

Cymath solves math problems step by step using artificial intelligence and heuristics, with coverage of algebra, calculus and graphing on Android, iOS and the web. Algebra topics include equation solving, factoring, logarithms, exponents, complex numbers, quadratic equations, trigonometry, partial fraction decomposition and polynomial division. Calculus includes product, quotient and chain rules, along with u-substitution, integration by parts and trigonometric substitution. Graphing features can generate graphs and identify intercepts, asymptotes, domains and ranges. The website also offers practice problems in pre-algebra, fractions, algebra and calculus, with full solutions and steps. On iOS, a user can capture a problem with the camera instead of typing it. The free plan provides step-by-step solutions. Cymath Plus costs $5 a month and adds ad-free use, detailed sub-steps and explanations on most problems, bookmarks, solution history, definitions and examples; cancellation is available at any time.

PARI/GP is a free, open-source computer algebra system designed for fast number-theory computations. Its functions cover factorization, algebraic number theory, elliptic curves, modular forms, L-functions, matrices, polynomials, power series, algebraic numbers, and transcendental functions. PARI is available as a C library; gp is an interactive shell, and GP is its scripting language. The gp2c compiler translates a subset of GP scripts to C and can make compiled scripts three or four times faster. The official site offers a browser-based GP interface for expressions, variables, and function definitions, though its stated speed is approximately 15% of native speed. Xeus-GP is a Xeus-based Jupyter kernel. Optional packages are distributed separately because they use substantial disk space and are expected to be unnecessary for most users. The project provides guides, reference manuals, tutorials, quick reference cards, and downloadable manuals. The project directs users to a mailing list for help and a bug tracker for reports and feature requests. It is licensed under GNU GPL version 2 or later.
