Calculator Graphs Multiple Equations

  • 12/01/95
The EL-9300C simplifies problem-solving by allowing solutions to be presented in many formats. The calculator features a high-contrast LCD screen and user-friendly functions. An equation editor enables equations to be entered, edited and viewed just as they appear in textbooks, rather than as a single line. An efficient menu system offers fast access to a variety of operations. Up to four equations can be graphed and analyzed at once. Statistics are presented in a "card" format, with each card representing one data set or observation. Data can be viewed in up to seven types of graph. Additionally, the unit has 32K RAM, a backup battery and a communications port to link to another calculator, printer or overhead model. Sharp Electronics Corp., Mahwah, NJ, (800) BE-SHARP.
