Alson, Pedro – Focus on Learning Problems in Mathematics, 1989
Presents a device for sketching the graph of the composite and inverse of single variable real-valued functions. Discusses some didactic methods of paths. (YP)
Descriptors: College Mathematics, Functions (Mathematics), Graphs, Mathematical Concepts
Konvisser, Marc – Focus on Learning Problems in Mathematics, 1989
Discusses a technique for graphically composing functions. Describes three-step composition procedures in two- and three-dimensional rectangular coordinate systems. Provides three examples. (YP)

Janvier, Claude; Garancon, Maurice – Focus on Learning Problems in Mathematics, 1989
Shows that graphs can reveal much about feedback systems that formula conceal, especially as microcomputers can provide complex graphs presented as animations and allow students to interact easily with them. Describes feedback systems, evolution of the system, and phase diagram. (YP)
Descriptors: Computer Simulation, Computer Uses in Education, Diagrams, Feedback
