This article offers an engaging application that adds meaning to the binomial theorem. (Contains 8 figures.)

Since the 1999 fall semester, the TI-92 Plus or the TI-89 has been a compulsory purchase for new students entering one engineering school in Montreal, Canada (almost 1000 enrolments a year). The purpose of this paper is to share impressions of a campus-wide experience and to communicate solutions adopted to help students and faculty members in the…

A previously developed program for the HP-41C programmable calculator is extended to handle models of differential and difference equations with multiple eigenvalues. How to obtain difference equation solutions via the Z transform is described. (MNS)

Provides instructions for and examples of balancing chemical equations using a desktop calculator. (JN)

This article on mathematics in the curriculum describes how students learn the characteristics of conic section equations by entering them into graphing calculators to make happy faces in a high school or college algebra class. A sample worksheet page is included. (Author/LRW)

This paper extends the discussion of the critical line approach using three risky stocks as described in Haugen's Modern Investment Theory, 4th edition. A dynamic presentation of the concepts involved in finding the efficient set, using two EXCEL spreadsheets and an HP-12C hand-held calculator, is provided. This dynamic presentation will enable…

Some tips that combine knowledge of mathematics history and technology for adapting Ferrar's method to factor quintics with a TI-83 graphing calculator are presented. A demonstration on the use of the root finder and regression capabilities of the graphing calculator are presented, so that the tips can be easily adapted for any graphing calculator…

A combination of graphical thinking with chemical and physical theories in the classroom is encouraged by using the Calculator-Based Laboratory System (CBL) with a temperature sensor and graphing calculator. The theory of first-order kinetics is logically explained with the aid of the cooling or heating of the metal bead of the CBL's temperature…

Procedural evaluations of limits of functions provide invariably better understanding of the limits than the approximations using a calculator. The purpose of this article is to demonstrate that better understanding can be promoted if mathematical understanding precedes the impulse to use calculators. The note clarifies the stages when the…

This article offers an introductory activity for the limit concept with a geometrical and historical foundation. A connection among Geometry, Measurement and Calculus is highlighted with the help of technology. The geometrical drawing, measurement and graphing capabilities of both TI-89 and Geometer's Sketchpad make it possible for students to…

Not all educators agree that the best ways to teach mathematics include giving students electronic calculators. But many do, and their view is reflected in the policies and practices of school districts, textbook publishers, testing companies, and state education agencies. That adds up to profits for Texas Instruments Inc., the Dallas-based…

"C[squared] = Creative Coordinates" is an engaging group of tasks that fosters the integration of mathematics and art to create meaningful understanding. The project lets students illustrate of find an image, then plot points to map their design on a grid. The project usually takes about a week to complete. When it is finished, students who are…

Drawing from experiences at Ohio State University (OSU) with remedial college students and with 12th grade students without elementary algebra skills, this paper outlines a numerical approach to algebra instruction using handheld calculators. Introductory material discusses problems with traditional approaches to math education and outlines some…

Provides a rationale for using calculators to study large numbers in the elementary school. Suggests that calculators be used to encourage children to develop their interest in large numbers, to become more adventurous in their explorations of them, and to stimulate their curiosity in their occurrence.
