Young, Anne Ludington – Primus, 1997
Describes a Calculus I project in which students discover the formula for the derivative of an exponential function. The project includes two targeted writing assignments and leads to several additional problems. Together these tasks provide a basis for an algebraic approach to the exponential function. (AIM)

Lucas, John F. – Primus, 1993
This paper merges state-of-the-art calculator technology with examples drawn from the Harvard Consortium Calculus Curriculum. A brief rationale for selection of the Harvard project and the TI-85 is provided, and four different mathematical situations are examined using different capabilities of the TI-85. Two short TI-85 programs are given.…

Shulman, Bonnie – Primus, 1998
Discusses the importance of history and original sources in motivating students to learn content. Describes how a simple question led to a fascinating quest through primary sources. Claims that once collected, these sources proved to be a treasure trove of material illuminating mathematics and mathematicians in an historical context. Contains 18…

Mathews, Susann; Mathews, Kirk – Primus, 1999
Demonstrates examples, one of which is an extension of "guess and check," to include variables rather than numbers. The quadratic equation az2+bz+c=0, is solved by assuming a complex solution of the form z=x+iy. Explores the use of deMoivre's theorem in deriving trigonometric identities with other examples.

Heller, William H.; Taylor, Monty B. – Primus, 2000
Discusses the authors' experiences with integrating financial calculators into a business mathematics course. Presents a brief overview of the operation of financial calculators, reviews some of the more common models, discusses how to use the equation solver utility on other calculators to emulate a financial calculator, and explores the…
