Zona Land, created by Ed Zobel, is a science and mathematics resource site for students and teachers. The site illustrates mathematical and physical principles by the use of Java applets and VRML simulations. The Science section contains the Physics Department (mechanics, waves and light), EZ Graph, and EZ Evaluator. EZ Graph allows the user to view the graph of a desired function. Evaluator is an online calculator that has trigonometric capabilities. The Mathematics section has four subject areas plus the Graph and Evaluator tools. Graph Paper allows the user to examine the effects of different scales on pre-designed linear, cubic, quadratic, and sine functions. The Function Institute begins with an optional tour of the definition of a function. Also available at the Institute are graphs of linear and polynomial functions. The Geometry Section has three areas of resources: Common Shapes, Fractals, and Coordinate Geometry. Trigonometry Realms has a simple yet comprehensive introduction to trigonometry. Help is available for all of the different resource applications.
