What is Symbolic Math Guide?
Symbolic Math Guide is a concept calculator software application
that is part of Texas Instruments' ongoing research aimed at
helping students learn how to apply symbolic and algebraic
transformations using the TI-89 and the TI-92 Plus. It is currently
available only in a pre-beta release version.
Because it is more faithful to the mathematics and mathematical
notation found in textbooks than other calculator-based computer
algebra systems (CAS), Symbolic Math Guide makes it easier for
students to relate to the mathematics in their textbooks.
Symbolic Math Guide provides step-by-step problem-solving
transformations for several classes of symbolic computations from
algebra, pre-calculus, and calculus, including the following:
Simplify
Expressions using
powers
Polynomial expressions
Rational expressions
Radical expressions
Logarithmic &
Exponential expressions
Difference quotients
Solve
Linear equations
Quadratic equations
Rational equations
Radical equations
Logarithmic &
Exponential equations
Compute
Derivatives

Symbolic Math Guide performs all operations in strict
REAL
mode. It
treats non-real sub-expressions, +, and
M
as undefined.
Symbolic Math Guide provides the corresponding domain of
definition for which the original expression is real and finite. It also
generates domain preservation constraints whenever a selected
transformation would otherwise enlarge the domain of definition.
Symbolic Math Guide attempts to produce solutions consisting of
equivalent expressions or of equivalent equations.
The current version of Symbolic Math Guide does not support
languages other than English. The calculator language mode must
be set to English to ensure that the application performs correctly.
TI invites feedback from teachers and students concerning the
functionality and educational value of Symbolic Math Guide. Please
send your comments and questions to
concept@list.ti.com.
