SymbMath 2.0: A Symbolic Calculator with Learning

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 can easily edit the library (e.g. integral tables)
in "formula format".
(3) It requires only 640 KBytes RAM, so it can run on small
IBM PCs 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,
user-defined functions, built-in standard functions,
over 80 internal 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, etc.
Also included are:
o Pull-down and pop-up menus, sizable 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).
Its shareware version (SM20A.ZIP) is available free from the
Calculator directory in SIMTEL20 archives on many anonymous FTP sites
(wsmr-simtel20.army.mil, rana.cc.deakin.oz.au, garbo.uwasa.fi, etc) or
by e-mail from listserv@vm1.nodak.edu, listserv@ndsuvm1.bitnet.
