[. . . ] EL-9650 GRAPHING CALCULATOR MODEL EL-9650 GRAPHING CALCULATOR OPERATION MANUAL SHARP CORPORATION 00BUP (TINSE0397THZZ) PRINTED IN CHINA / IMPRIMÉ EN CHINE This equipment complies with the requirements of Directive 89/ 336/EEC as amended by 93/68/EEC. Dieses Gerät entspricht den Anforderungen der EG-Richtlinie 89/336/EWG mit Änderung 93/68/EWG. Ce matériel répond aux exigences contenues dans la directive 89/336/CEE modifiée par la directive 93/68/CEE. Dit apparaat voldoet aan de eisen van de richtlijn 89/336/EEG, gewijzigd door 93/68/EEG. [. . . ] Move the cursor pointer to [ ] at the left of the screen and touch [ ] or keep ® pressed to gradually move the graph to the right. Press to view the full graph. (Move the Y-axis to the center of the screen. ) * The initial screen that appears for Rapid Zoom may differ from that shown in the example, depending on the Window settings. 129 CHAPTER 4 (4) Split screen · The calculator provides a split screen function which allows you to view the graph and table or the graph and graph equation at the same time. This function is valid in all coordinate system modes. Graph and table Graph and equation * The area where the cursor is located is reversely displayed. · To enter the split screen, press Ï . · When Ï are pressed on the graph screen, the graph and table are displayed on the same screen. · When Ï are pressed on the equation input screen, the graph and equation are displayed on the same screen. The following illustration shows these relationships. Ï Ï Ï 130 GRAPHING FUNCTIONS · The split screen is always in the trace mode. Accordingly, the coordinate values are reversely displayed in the table and the equation at which the cursor pointer is located is also reversely displayed. (Values reversely displayed in the table are also changed accordingly. ) · When two or more graphs are displayed on the screen, a desired graph is selected using or . (Accordingly, the table or equation on the right of the screen is also changed. ) · The table on the split screen does not relate to the table settings on the table fullscreen. · The table on the split screen is displayed in units of trace movement amount based on the cursor pointer position on the graph screen. When the table full-screen is displayed by pressing , a different table may appear on the screen. · When the EXPRES or Y' is set to ON on the FORMAT menu, the equation or coordinates are displayed on the graph screen. · Only equations whose graphs can be drawn are displayed on the split screen. · Press or on the split screen to display the full-screen of the graph or table. To exit the split screen, press any of other function keys. (5) Substitution graph · The substitution graph allows you to input an equation using characters and variables, and substitute numeric values for the characters to draw its graph. · The substitution graph is valid only in the rectangular coordinate system. Using this function, any number of numeric value sets can be substituted while referring to the graph drawing screen. This clearly shows the changes in the graph depending on numeric values. For example, the graph for "Y1 = AX3 + BX2 + CX2 ­ D" is drawn by substituting numeric values for variables A, B, C, and D of the equation. 131 CHAPTER 4 · · 22 kinds of variables (characters), A to Z except for R, T, X, and Y can be used for the substitution graph. (If the equation contains more than seven variables (characters), up to seven characters from the top of the equation are determined as variables and subsequent characters are ignored. ) If you attempt to execute an equation containing no variables, the substitution graph becomes invalid and the error message, "NO VARIABLE", appears on the screen. To input the equation, there are the following two methods after has been pressed. After the equation has been input, the same operations apply to subsequent steps. · · 1Input an equation directly. <Example> Input "AX2 + B" to "Y1".
