Internet Access All students have access to the Internet in the Library, which at Northridge is in the middle of the second floor of Building 1000. If you're new to computers or the Internet, there will be someone at that location who can help you get started.   Top of This Document   Free Graphing Software GraphEQ (versions for Windows and Mac) xFunctions -- Mac OS graphing program. Very intuitive with lots of pull-down menus and on-screen help. WinPlot -- Windows OS graphing program. A guide for using WinPlot is available. Top of This Document   Web Page Function Graphers Java Function Grapher works within your browser. To enter a function, don't type "y=" or "f(x)="; just type the function's formula. There is no "Print" feature. If you want to print a graph, you'll first have to do a "Screen Capture" or a "Print Screen." Fairly fast and very convenient. Top of This Document
