What is Symbolic Math Guide?

Symbolic Math Guide is a software application that is part of TIs' ongoing research aimed at helping students learn how to apply symbolic and algebraic transformations using the TI-89, TI-92 Plus, and VoyageTM 200.

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

Monomials Polynomials Rational expressions Radical expressions

Expand Solve

Logarithmic & exponential expressions

Linear equations Quadratic equations Rational equations

Compute Other

Derivatives Axioms & Laws Identity

Logarithmic & exponential expressions Trigonometric expressions Difference quotients Generic expressions Trigonometric equations Generic expressions Radical equations Logarithmic & exponential equations Generic expressions Indefinite integrals Factor

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 change the domain of definition. Symbolic Math Guide attempts to produce solutions consisting of equivalent expressions or of equivalent equations.
