This text is an integrated presentation of a second year course in algebra and trigonometry and digital computer modeling techniques using the programming language BASIC. Computer concepts are used directly with the mathematics throughout the text. No attempt is made to develop especially proficient programmers, but rather to present computer…

The course outline has been prepared as a guide to assist the student in becoming proficient in trigonomical functions. This aids a machinist in making a complicated set-up so that he can perform a precision machine operation. The guide helps the instructor concentrate on the specific review that will be needed. After the review, the student is…

Designed for the student who has competence in general mathematical skills and who has interest in solving practical problems, this guidebook on minimum course content seeks further development of computational and problem solving skills through the applications of trigonometry and base ten logarithms. Overall course goals are specified, a course…

The first of a two-part sequence for the student who has had difficulty in second-year algebra, this booklet covers definitions and measurement of angles (in degrees and radians), the trigonometric functions, solving trigonometric equations and graphing functions, identities, and computation with base ten logarithms. Overall goals for the course…

This booklet is the second of a two-part sequence of minimum content for trigonometry. It includes sum, difference, double-angle, and half-angle formulas; Law of Sines; Law of Cosines; inverse trigonometric functions; polar coordinates; and DeMoivre's Theorem. Goals, performance objectives for each unit, a course outline, references to…

Examples of the presentation and solution of variations on a common projectile trajectory problem are presented. (BB)

Several geometric and trigonometric proofs are discussed. These proofs were selected from a larger group because of their instructional value promoting enrichment or generalization. (SD)

An application of trigonometry in weather forecasting, dealing with cloud height, is discussed. (MNS)

Algebraic and transcendental curves are discussed, with attention focused on computing the area of some special regions bounded by the curves. (MNS)

The given proof supplements the derivation of identities provided in textbooks. Illustrations are included. (MNS)

In this section, suggestions are given for working with radian measures, proving logarithmic properties, the law of cosines as seen by Pythagoras, and an alternative proof of a theorem. (MNS)

Some traditional and some less conventional approaches using the cotangent to solve the same problem are described. (MNS)

This book presents motivational ways to teach key concepts and topics common to all secondary mathematics curricula. It is arranged by subject matter which includes algebra, geometry, trigonometry, probability, statistics, and miscellaneous topics. The objective to be attained by implementing the unit on each of these subjects is stated, and the…

This article shows how simple instruments may be used to construct angles of certain measures and applies this procedure to more detailed problems. A proof of the Pythagorean Theorem is given using these procedures. (CT)
