A computer program is given to simulate the operation of the Galton quincunx, a device to approximate a normal distribution. (MNS)

The general algorithm used in most hand calculators to approximate elementary functions is discussed. Comments on tabular function values and on computer function evaluation are given first; then the CORDIC (Coordinate Rotation Digital Computer) scheme is described. (MNS)

The problem "Given three planar points, find a point such that the sum of the distances from that point to the three points is a minimum" is discussed from several points of view. A solution that uses only calculus and geometry is examined in detail. (MNS)

A method of using vector analysis is presented that is an application of calculus that helps to find the best angle for tacking a boat into the wind. While the discussion is theoretical, it is seen as a good illustration of mathematical investigation of a given situation. (MP)

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

A description of the development of three-valued logic includes construction of truth tables. (MK)

A method for teaching the product rule of differentiation in calculus is described. (MK)

Clarified is the assertion that the so-called complementary function is indeed the general solution of the homogeneous equation associated with a linear nth-order differential equation. Methods to obtain the particular integral, once the complementary function is determined, are illustrated for both cases of constant and of variable coefficients.…

This paper first defines the bridge club scheduling problem that was presented to the author and then explores the meaning of an optimal solution. Next, an analytical solution is sought based on the classification of the problem as a resolvable partially balanced incomplete block design. Finally, four increasingly sophisticated techniques of…

Described are ways that errors of magnitude can be unwittingly caused when using various supercalculator algorithms to solve linear systems of equations that are represented by nearly singular matrices. Precautionary measures for the unwary student are included. (JJK)

Described is the hand-calculation method for the orthogonalization of a given set of vectors through the integration of Gaussian elimination with existing algorithms. Although not numerically preferable, this method adds increased precision as well as organization to the solution process. (JJK)

Considers some changes that the use of graphics calculators impose on the assessment of calculus and mathematical modeling at the undergraduate level. Suggests some of the ways in which the assessment of mathematical tasks can be modified as the mechanics of calculation become routine and questions of analysis and interpretation assume greater…

Vietnamese students now enrolled in American high schools incur an extremely special need in English. After being taught subject matter disciplines in Vietnamese for many years, and while English is still a foreign language for them, these students are bound to go through two linguistic processes. First, while reading or sitting through lectures…

This paper discusses the problems associated with mathematics anxiety, and provides detailed information on the history and structure of the Mathematics Anxiety Program at the University of Minnesota. The seven parts concern: (1) the Continuing Education for Women Program, (2) the development of the Math Anxiety Program, (3) the symptoms of…

This study details the establishment of a teacher/learner laboratory at Monash University in Australia and the information it yielded about the learning and teaching of mathematics. Both instructors and learners understood they were cooperating to help develop an understanding of difficulties in learning and teaching strategies and ways to reduce…
