Computing Large Factorials.
Peer reviewed Peer reviewed
Kiernan, Gerard – College Mathematics Journal, 1985
Provides several algorithms that use extended precision methods to compute large factorials exactly. The programs are written in BASIC and PASCAL. The approach used for computing N considers how large N is, how the built-in limitation on exact integer representation can be bypassed, and how long it takes to compute N. (JN)

Graphing Calculators in the Secondary Mathematics Classroom. Monograph #21.
Eckert, Paul; And Others – 1989
The objective of this presentation is to focus on the use of a hand-held graphics calculator. The specific machine referred to in this monograph is the Casio fx-7000G, chosen because of its low cost, its large viewing screen, its versatility, and its simple operation. Sections include: (1) "Basic Operations with the Casio fx-7000G"; (2) "Graphical…

Microcomputer Calculation of Thermodynamic Properties from Molecular Parameters of Gases.
Peer reviewed Peer reviewed
Venugopalan, Mundiyath – Journal of Computers in Mathematics and Science Teaching, 1990
Described in this article is a problem-solving activity which integrates the application of microcomputers with the learning of physical chemistry. Students use the program with spectroscopic data to calculate the thermodynamic properties and compare them with the values from the thermochemical tables. (Author/KR)
