1. Introduction
1.1 What is SymbMath
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 the integrals of an unknown function from a derivative of that
unknown function).
SymbMath is a programming language in which you can write
programs, functions and procedures.
SymbMath is a symbolic, numeric and graphics computing
environment where you can set up, run and document your calculation,
and draw your graph.
SymbMath is database where you can search your database.
SymbMath is a multi-windowed text editor in which you can edit
many documents in many windows.
It runs on IBM PCs (8086) with 400 KB free memory under MS-DOS.
1.2 Capabilities
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 User-defined functions: conditional, case, piecewise, recursion.
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, indeterminate forms.
o Complex: calculation, functions, derivatives, integration.
o Sum and product: partial, finite or infinite.
o Others: series, lists, arrays, vectors, matrices, tables, etc.
Also included are:
o Pull-down and pop-up menus, resizable and colourable windows.
o Programming in integrated edit-interpret-debug environment.
o On-line help, and on-line manual.
o Procedural, conditional, iterational, recursive, functional,
rule-based, logic, pattern-matching and graphic programming.
o Autoloaded library in the SymbMath language.
o Plotting functions and graphing.
o Searching database.
1.3 Shareware, Student and Advanced Versions
You should register with the author if you use SymbMath.
Please read the document file SymbMath.DOC and all *.TXT files
before running SymbMath. You should print them out if you need the printed
documents. Please follow examples in the document to practise.
On the MS-DOS prompt to install it, type
install
On the MS-DOS prompt to run it, type
SymbMath
SymbMath has three versions: Shareware Version A, Student
Version B and Advanced Version C. The shareware version lacks the
solve(), trig (except sin(x) and cos(x)), and hyerbolic functions,
(lack 10% keywords) and the student version lacks the hyerbolic
functions (lack 5% keywords). You cannot input these lack functions
in shareware or student version.
----------------------------------------------------------------------
Version Class Lacked Functions Price
Shareware A solve(), hyerbolic, US$10 or AU$15
trig (except sin(x), cos(x))
Student B hyerbolic US$50 or AU$70
Advanced C US$99 or AU$140
Libraries *.(x) US$20 or AU$25

Other foreign money is accepted at the current exchange rate.
You must provide the photocopy of your license or license
number for upgrades.
If you send the author your payment by cheque, money order
or bank draft that must be drawn in Australia, you will get the
latest version. If you sign the license (see the LICENSE.TXT file)
and send it to the author, you will be a legal user for upgrades.
If you write a paper about this software on publication, you will get
a free upgrade.
It has three versions: Shareware, Student, and Advanced. The
shareware version is available from SIMTEL20 archives on anonymous FTP
sites (e.g. oak.oakland.edu in /pub/msdos/calculator as sm30a.zip).
