Resumen de Comparisons and Demonstrations of Scientific Calculators
Myung-Hoon Kim, Suw-Young Ly, Tae-Kee Hong
Scientific calculators are classified into four types: Basic, Intermediate, Advanced-I, and Advanced-II. They are compared in terms of their capacities, featuring many advantages of the graphic calculator over simple nongraphic calculators. Built-in software packages with the advanced calculators include graphing programs, an equation solver with numerical methods, matrix algebra for solving simultaneous equations, and advanced statistics including a nonlinear least squares regression. Applications in this paper include a simulation of acid-base titration curves, and graphic display of a time course of concentrations of reactants and products for a chemical reaction with first-order kinetics. Ready demonstrations of graphic results from a quantitative chemical problem are particularly advantageous with the advanced graphic calculators.
