The Inequality Graphing application for the TI-83 Plus gives you new features for graphing equations and inequalities and evaluating the relationship between them. Using the Inequality Graphing application, you can ?enter inequalities using relation symbols graph inequalities and shade the union and intersection regions enter inequalities (vertical lines only) in an X=editor trace points of interest (such as intersections) between relations store (x, y) coordinate pairs to lists for viewing and optimizing functions for linear programming Inequality Graphing is available in two different versions, English only and international. The international version contains the English version and also supports Dutch, French, German, Portuguese, and Spanish. [. . . ] The window shifts and the graph is redrawn. 5. The exact coordinates of the point of interest are displayed. Method 2 1. Press ` to activate the PoI-Trace mode. Coordinates for the point of interest are displayed. Press y / to display the CALCULATE screen. Select 5:intersect. Inequality Graphing for the TI-83 Plus Page 29 4. The cursor moves to a point on one of the curves and displays First curve?If want to find an intersection point on this curve, press . If you do not want to find an intersection point on this curve, move the cursor to the correct curve and press . Repeat step 3 for the second curve. 6. Move the cursor as close to the intersection point as you can and press . Inequality Graphing for the TI-83 Plus Page 30 The exact intersection point that is closest to where you placed the cursor is displayed. Graph of intersection (zoomed in) Storing Coordinates of Points You can store coordinates of points to lists so that you can use them in evaluations. You can also select or deselect individual Y-variables (you cannot select or deselect individual X-variables): 1. Press . Inequality Graphing for the TI-83 Plus Page 37 System Integration The Inequality Graphing application is integrated in to the system except in the following situation: When you access the Y-variables from outside the Y=editor, such as in the table editor or the home screen, they are treated as equations rather than inequalities. Example: In the Inequality Graphing application Y=editor, Y1 | 2X+4 On the home screen, 3 Y1 = 72 (where x=10 due to the default Xmax Window setting) Inequality Graphing for the TI-83 Plus Page 38 Deleting Inequality Graphing from the TI-83 Plus To delete the application from your calculator: 1. Press {. Inequality Graphing for the TI-83 Plus Page 39 Inequality Graphing Warning and Error Messages Inequality Graphing Warning Messages Message Duplicate point List Editor full Description You have selected coordinates to store to LINEQX and LINEQY that have already been stored. The list editor already contains the maximum of 20 lists. LINEQX and LINEQY will be stored on your calculator, but will not appear in the list editor. and LINEQY contain different numbers of elements. Select one of the following options: LINEQX List mismatch 1:Cancel to cancel storing the points. 2:Clear (INEQX, INEQY to delete all elements from LINEQX and LINEQY and store the selected point coordinates. (LINEQX, LINEQY) must be real lists (LINEQX, LINEQY) already full or LINEQY (or both) are complex lists. Press S [ to clear the lists so that you can store the selected point coordinates. LINEQX The lists LINEQX and LINEQY contain 999 elements. Delete some elements or clear the lists so that you can store the selected point coordinates.
