- SymbMath also runs effectively on a small IBM PC 8086-class machines
- and you can declare a variable to be real, positive, negative, etc.
- Here is some info about it.

- SymbMath (an abbreviation for Symbolic Mathematics) is not
- only a symbolic calculator but also an expert system that can solve
- symbolical math problems. SymbMath will also perform exact numeric
- computation. It can manipulate complicated formulas and return answers
- in terms of symbols, formulas and exact numbers.
- SymbMath is different from other software:
- (1) It is able to learn from users. If users only input one
- formula (e.g. one derivative) without writing any code,
- it will automatically learn many problems (e.g.
- derivatives, indefinite and definite integrals) related
- to this formula.
- (2) Users edit the library (e.g. integral tables) in "formula
- format" by any text editor.
- (3) It runs on small IBM PCs (8086) with 640 KB RAM under MS-DOS.
- Its capabilities include facilities to provide analytical and
- numerical answers for:
- o Differentiation: regular or higher order, partial or
- total, mixed and even implicit differentiation,
- one-sided derivatives.
- o Integration: indefinite or definite integration,
- multiple integration, infinity as a bound, parametric
- integration, iterated integration, line or surface
- integrals, discontinuous or implicit integration.
- o Solution of equations: roots of a polynomial, systems of
- algebraic or differential equations.
- o Manipulation of expressions: simplification, factoring or
- expansion, substitution, evaluation, built-in standard or
- user-defined functions.
- o Calculation: exact and floating-point numerical
- computation of integer, rational, real and complex
- numbers in the range from minus to plus infinity, even
- with different units.
- o Limits: real or complex limits, one-sided limits,
- indeterminate forms.
- o Complex: calculation, functions, derivatives, integration.
- o Sum and product: finite or infinite, partial.
- o Chemical calculation: molecular and atomic weights,
- concentrations (all by entering the symbols of the
- chemical elements).
- o Chemical reactions: inorganic and organic.
- o Other: series, lists, arrays, vectors, matrices, tables, etc.
- Also included are:
- o Pull-down and pop-up menus, resizable and colourable windows.
- o Twin screen text editor with syntax check.
- o Programming in integrated edit-interpret-debug environment.
- o Reading and generating BASIC and FORTRAN codes.
- o Displaying two-dimensional math notation.
- o On-line help, and on-line manual.
- o Interface with other software (e.g. with PlotData for graph).
- It has three versions: Shareware, Student, and Advanced. The
- shareware version is available from SIMTEL20 archives on anonymous FTP sites
- (wsmr-simtel20.army.mil as /calculator/sm21a.zip, rana.cc.deakin.oz.au as
- /huang/sm21a.zip, etc) or by e-mail from listserv@ndsuvm1.bitnet.
