Plotting a polynomial over the range of real numbers when its derivative contains complex roots is discussed. The polynomials are graphed by calculating the minimums, maximums, and zeros of the function. (MNS)

General physics students have difficulties interpreting experimental data and finding mathematical functions that produce curves resembling typical data. Proposes utilizing computer programs that generate graphs to develop function-recognition and curve-fitting skills. Discusses advantages of computerized curve fitting. (MDH)

Discusses the early recognition of chaos as seen in Poincar's work solving dynamical problems. Proposes five examples from which an inventory of the manifestation of chaos can be inferred. Discusses some instructional consequences of the development of ideas of chaos. (MDH)
