Device and method for the graphical representation of mathematical formulas

摘要

A color display device for displaying graphs in various colors, a color designation unit for designating colors of the graphs displayed and a control unit (11). First, functional expression data to be displayed in a graph is input by a key-in unit (12). A display color for the graph is designated by the color designation unit (20) for the input functional expression data. A graph is calculated from the input functional expression data in accordance with the designation of graph display. The control unit (11) displays the calculated graph in a color designated by the color designation unit (20). In this arrangement, different display colors are designated for the respective graphs in order to display those graphs together in an easily recognized manner. IMAGE
