The use of mathematical ideas in linguistics is illustrated by a discussion of a transformational grammar. (MM)

Discussion includes the aims of mathematics instruction with special reference to applied vs. theoretical teaching purposes. A plea for math-science professional co-operation and a discussion of the New Math" is included. (JG)

Part I reviews the mathematical definition of function, and then presents some practical uses of functions in such areas as substitution in a formula, equation solving, and curve fitting. Part II gives examples of functions that can be used to describe some real life situations. (RP)

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)

Some of the important concepts in recursive programing are detailed, along with how they can be used. Examples are provided to show how to program recursively in BASIC. (MP)

Considers the electrostatic problem of a point charge in a domain bounded by conducting planes. Lists all such domains for which a solution by images exists, describes the image charge arrays in familiar crystallographic terms, and gives an illustrative example. (Author/GS)

Presents a mathematics problem involving speed of a walking student versus speed of light reflection in a high school hallway. (MKR)

Explains standard drawing layouts and rules for creating orthographic and isometric views of a three-dimensional object. Normal and inclined surfaces are also discussed. Concludes with recommended classroom activities. Includes reproducible student worksheets. (FDR)
