Erable
Erable is a computer algebra system (CAS) for a family of Hewlett-Packard graphing scientific calculators of the HP 40, 48 and HP 49/50 series. History Originally named ''ALGB'' in 1993, it was developed by the French mathematician for the HP 48SX. Over time, the system integrated a lot of functionality from another math pack for the HP 48 series, ALG48 by Mika Heiskanen and Claude-Nicolas Fiechter. At some point, ''ALGB'' was renamed into ''Erable'', a French play-on-words on another CAS named Maple. Compatible with the HP 48S, 48SX, 48G, 48GX, and 48G+, Erable became one of the "must-have" software packages to be installed by advanced users of these calculators. When Hewlett-Packard developed the HP 49G in 1999, the Erable and ALG48 packages became an integral part of the calculator's firmware, now just named ''HP49 CAS''. As HP CAS it also showed up in the HP 40G, 40gs, 49g+, 48gII and 50g and was maintained by Parisse up to 2006 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comparison Of Computer Algebra Systems
The following tables provide a comparison of computer algebra systems (CAS). A CAS is a package comprising a set of algorithms for performing symbolic manipulations on algebraic objects, a language to implement them, and an environment in which to use the language. A CAS may include a user interface and graphics capability; and to be effective may require a large library of algorithms, efficient data structures and a fast kernel. General These computer algebra systems are sometimes combined with "front end" programs that provide a better user interface, such as the general-purpose GNU TeXmacs. Functionality Below is a summary of significantly developed ''symbolic'' functionality in each of the systems. via SymPy via qepcad optional package Those which do not "edit equations" may have a GUI, plotting, ASCII graphic formulae and math font printing. The ability to generate plaintext files is also a sought-after feature because it allows a work to be understood by people wh ...

HP 40 Series
HP 39/40 series are graphing calculators from Hewlett-Packard, the successors of HP 38G. The series consists of six calculators, which all have algebraic entry modes, and can perform numeric analysis together with varying degrees of symbolic calculation. All calculators in this series are aimed at high school level students and are characterized by their ability to download (via cable or infrared) APLETs or E-lessons. These are programs of varying complexity which are generally intended to be used in the classroom to enhance the learning of mathematics by the graphical and/or numerical exploration of concepts. HP 39g The HP 39g (F1906A) was released in 2000. Basic characteristics: * CPU: 4 MHz Yorke (Saturn core) * Communication: Proprietary infrared, serial RS-232 (serial port). * Memory: 256 KB RAM * Screen resolution: 131 × 64 pixels * Includes a hard cover * Limited symbolic equation functionality. HP 40g HP 40g (F1907A) was released in 2000 in p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HP 49G
The HP 49/50 series are Hewlett-Packard (HP) manufactured graphing calculators. They are the successors of the HP 48 series. There are five calculators in the 49/50 series of HP graphing calculators. These calculators have both algebraic and RPN entry modes, and can perform numeric and symbolic calculations using the built-in Computer Algebra System (CAS), which is an improved ALG48 and Erable combination from the HP 48 series. It is widely considered the greatest calculator ever designed for engineers, scientists, and surveyors. It has advanced functions suitable for applications in mathematics, linear algebra, physics, statistical analysis, numerical analysis, computer science, and others. Although out of production, its popularity has led to high prices on the used market. HP 49G The HP 49G (F1633A, F1896A), was released in August 1999. The 49G incorporated many of the most powerful interface and mathematics tools available on the HP 48 series into the firmw ...

Giac (software)
Xcas is a user interface to Giac, which is an open source computer algebra system (CAS) for Windows, macOS and Linux among many other platforms. Xcas is written in C++. Giac can be used directly inside software written in C++. Xcas has compatibility modes with many popular algebra systems like WolframAlpha, Mathematica, Maple, or MuPAD. Users can use Giac/Xcas to develop formal algorithms or use it in other software. Giac is used in SageMath for calculus operations. Among other things, Xcas can solve differential equations (Figure 3) and draw graphs. There is a forum for questions about Xcas. CmathOOoCAS, an OpenOffice.org plugin which allows formal calculation in Calc spreadsheet and Writer word processing, uses Giac to perform calculations. Features Here is a brief overview of what Xcas is able to do: * Xcas has the ability of a scientific calculator that provides show input and writes pretty print * Xcas also works as a spreadsheet; * computer algebra; * 2D geometry ...
