Overview

ALG48 is a comprehensive symbolic math package for the HP48. It includes commands for algebraic simplification, factorization, partial fraction expansion, symbolic integration,symbolic matrices manipulation, and for solving systems of nonlinear polynomial equations.

ALG48 differs from other math packages for the HP48 in two important aspects:

  1. ALG48 can manipulate, simplify, and factorize multivariate polynomials and functions, i.e., algebraic expressions with several variables.
  2. ALG48 only does exact calculation, using unlimited precision integers and advanced computer algebra algorithms (as opposed to doing approximate calculation using floating point numbers and numerical algorithms). This not only means you will not get wrong or approximate results (2.00001, 4.9999 and the like), but also that all and only exact simplifications are performed.

Below are some examples of ALG48 operations. The time taken for the commands on a HP48GX (with  60K free) are given in brackets.

Additional features include:
