You can find it in Internet. Here is pointer:

SymbMath (an abbreviation for Symbolic Mathematics) is a symbolic
calculator that can solve symbolic math problems.
SymbMath is a computer algebra system that can perform exact
numeric, symbolic and graphic computation. It manipulates complicated
formulas and returns answers in terms of symbols, formulas, exact
numbers, table and graph.
SymbMath is an expert system that is able to learn from user's
input. If the user only input one formula without writing any code,
it will automatically learn many problems related to this formula
(e.g. it learns many integrals involving an unknown function f(x)
from one derivative f'(x) ).
SymbMath is a symbolic, numeric and graphics computing environment
where you can set up, run and document your calculation, draw your
graph, and use external functions in the same way as standard
functions since the external functions are auto-loaded.
SymbMath is a programming language in which you can define
conditional, case, piecewise, recursion, multi-value functions and
procedures, derivatives, intergrals and rules.
SymbMath is database where you can search your data.
SymbMath is a multi-windowed editor in which you can copy-and-
paste anywhere in a file and between files, even from the Help file.
It runs on IBM PCs (8086) with 400 KB free memory under MS-DOS.
It can provide analytical and numeric answers for:
o Differentiation: regular or higher order, partial or total,
mixed and implicit differentiation, one-sided derivatives.
o Integration: indefinite or definite integration, multiple
integration, infinity as a bound, parametric or 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.
o Calculation: exact and floating-point numeric computation
of integer, rational, real and complex numbers in the range
from minus to plus infinity, even with different units.
o Limits: real, complex or one-sided limits.
o Complex: calculation, functions, derivatives, integration.
o Sum and product: partial, finite or infinite.
o Others: series, lists, arrays, vectors, matrices, tables.
Also included are:
o Plot: functions, polar, parametric, data, and list.
o Draw: lines, arcs, ellipse, cirlces, ovals.
o Auto-loaded library in the source code.
o Pull-down and pop-up menus, resizeable and colorable windows.
o Procedural, conditional, iterational, recursive, functional,
rule-based, logic, pattern-matching and graphic programming.
o Searching database.
Its two versions (Shareware and Advanced) are available from the
author. The shareware version is available from anonymous FTP sites
(e.g. ftp://ftp.unsw.edu.au/pub/UNSW/symbmath/sm332a.zip).
If you get the SymbMath on ZIP format (e.g. sm332a.zip), you
should unzip it with parameter -d by
pkunzip -d sm332a c:\symbmath
