A handout, developed for use with students at Arizona State University, describes Gaussian Elimination procedures to be used when working with matrices. (MK)

Matrix examples that have been used successfully in the classroom to illustrate group concepts are given along with observations made by students in working with them. (MN)

The attached materials have been developed for use on the CSU CYBER Computer's Statistical Package for the Social Sciences (SPSSONL). The assignments are graded in difficulty and gradually introduce new commands and require the practice of previously learned commands. The handouts begin with basic instructions for logging on; then XEDIT is taught…

A sequence of numbers from combinatorial theory called the Bell numbers is discussed, along with several problems and examples that demonstrate their usefulness. (MN)

This 8-page module summarizes a 16-page module produced by Undergraduate Mathematics and its Applications Project (UMAP). (MK)

Discussed are two Euclidean constructions (synthetic approach and coordinate method) to inscribe regular polygons of 5 and 17 sides in a circle. Each step of the constructions is described using diagrams and mathematical expressions. (YP)

Presents two papers commenting on previous published articles. Discusses formulas related to the determinants of sums and tests the formulas using some examples. Provides three special cases of the determinants of sums. (YP)

States that figures help students understand mathematical concepts and provide important clues for solving problems. Introduces some visual images that are effective in promoting mathematics learning. Describes the roles and characteristics of visual images and concludes that visual images can cultivate students' imagination and make them think…

This workbook is designed to be used as a review at the end of a college level course in algebra and trigonometry. Four review sheets containing 117 problems provide hints and detailed solutions for each problem. (YP)

A construction of an ellipse, given its foci and major-axis length 2a and using a compass and straightedge, is illustrated. It is based on Dandelin's elegant proofs that the sections formed by the intersections of a cone with a plane are an ellipse, parabola, or hyperbola. (MNS)

This booklet contains 11 modules (290 multiple-choice items) designed for use in the first course of a three-course calculus sequence using the textbook "Calculus with Analytic Geometry" (Dennis G. Zill). In each module, relevant sections of the textbook are identified for users. It can, however, be used in conjunction with any calculus textbook.…

Two areas of mathematics--continued fractions and dimensional analysis--are focused upon as topics that are teachable applications at the pre-calculus levels of mathematics. (MN)

A hand-held calculator is used to explore several easy and interesting mathematical topics involving compound and continuous interest suitable for beginning college students. (MN)

Details are given of a simple computer program written in BASIC which calculates the sine of an angle through an application of DeMoivre's Theorem. The program is included in the material, and the program's success is discussed in terms of why the approximation works. (MP)

Describes the development of the concept of function including changes of mental images, from the geometric conception versus the algebraic conception and the logical conception versus the algebraic conception. Lists 27 references. (YP)
