Considering a fraction as directions for graphing a line through the origin of the x-y plane is suggested. Strengths and weaknesses of the idea are also discussed. (MNS)

How tedious algebraic manipulations for simplifying general quadratic equations can be supplemented with simple geometric procedures is discussed. These procedures help students determine the type of conic and its axes and allow a graph to be sketched quickly. (MNS)

Experiences in collecting and handling data are described. Activities dealing with measures of central tendency (including a computer program), measures of dispersion, an introduction to correlation, and use of graphs to display data are illustrated. (MNS)

A sequence of exploratory activities is designed to help beginners use the BASIC language and make simple pictures by graphing pairs of numbers. (MNS)

Discusses the computer generated graphs that can present trends not apparent in the usual printouts of employee data. (IRT)

Methods for getting a computer-linked plotter to do a total plot of a relation are discussed. (DT)

This paper describes "The Migration Method," a new technique for graphing a quadratic function (one of the major foundations of undergraduate mathematics) and finding its zeroes. The method promotes a higher degree of conceptualization, reinforces the concept of symmetry, encourages mental visualization, and strengthens the ability to…

The author suggests having students work on the related inequalities to given equations comparing and graphing the three solutions on the same number line. Using individual activity cards, the student picks replacements and computes, continuing this process until they can determine the complete solution. (LS)

Part of a Ph.D. dissertation, University of Minnesota; results were presented in part at the 81st Meeting of the Acoustical Society of America, April 1971. (DD)

This article displays the graphs of number patterns obtained by writing each number in the pattern as an ordered pair, plotting the ordered pairs, and joining consecutive points by straight lines. (DT)

By changing the Euclidean metric definition, a new geometry is developed. Properties of figures are analyzed and theorems are proven in this new system. (DT)
