A computer program is presented that generates problem sets involving sketching graphs of trigonometric functions using graphical addition. The students use calculators to sketch the graphs and a computer solution is used to check it. (MP)

A method of approximating areas under curves in precalculus courses is described. (SD)

Describes a computer program that computes field lines and equipotential surfaces for a wide range of field configurations. Presents the mathematical technique and details of the program, the input data, and different modes of graphical representation. (MLH)

GrafTalk is a powerful, easy to use, business-oriented graphics package for producing pie, bar, and line-plot graphs. GrafTalk should run on nearly any CP/M-based system that drives a graphics device through serial/parallel output port. Discusses package installation, structure, documentation, and use, plotting scientific data, and comparison with…

Some experiences with a classroom computer graphics facility are recounted to show how such a facility has changed the views of some instructors teaching mathematics at the college level. Teachers are encouraged to search out and seize opportunities to acquire graphics hardware, with the added teaching capabilities promoted. (MP)

Presented are two computer programs which can be used to minimize the effort and time necessary to graph several individual functions. (TG)

An unusual shape is considered, and properties and steps in drawing it are detailed. The focus is on development and presentation of a computer program that will draw the curve. The program is written in BASIC with special plotting commands for a Techtronix computer, but is adaptable to other systems. (MP)

A program designed to plot three-dimensional graphs is described and presented. The program allows the user to select maximum and minimum ranges for X, Y, and Z, and can enlarge a graph on the screen or look at a portion away from the origin. It is in Applesoft BASIC. (MP)

This reprint of a Project Solo curriculum module discusses graphing by computer, gives an example of a BASIC program used to graph a second degree polynomial, and provides suggested exercises in programing. (MK)

An introductory unit on slope, designed to give students a chance to discover some of the basic relationships between functions and slopes, is described. Programs written in BASIC for PET microcomputers were used. It is felt that students have the background to understand derivatives after experiences with this unit. (MP)

Several problems involving "pi" and "e" can be approached by diagramming, flow charting, and computer programing. (SD)

A course that incorporates a computer program as a tool to take a more detailed look at differential equations is described. (MP)

Reviews software for college/advanced high school-level physics designed to instruct/test students in vector arithmetic and analysis. Written for Apple II/II+ (Applesoft), the program menu contains seven items (including graphing and straight line fitting procedure). Excellent use of graphics and sound tutorial approach keep students' interest and…

Experiences with complex numbers and graphical representations of them are discussed, with a program for a microcomputer. (MNS)
