[. . . ] 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. To run Inequality Graphing in a language other than English, you must have the corresponding language localization application installed and running on your calculator. Language localization applications are available for download free of charge in TI?s online store at epsstore. ti. com. Inequality Graphing for the TI-83 Plus Page 3 Where to Find Installation Instructions You can find detailed instructions on installing Flash applications at education. ti. com/guides. Inequality Graphing for the TI-83 Plus Page 4 Getting Started Getting Started is a fast-paced introduction that shows you some of the Inequality Graphing application?s features. [. . . ] 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 you do not want to find an intersection point on this curve, move the cursor to the correct curve and press . 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. The points are automatically stored in LINEQX (for x-values) and LINEQY (for y-values). If these lists already exist, new values are appended to the existing lists. (As explained later in this section, you can press to clear all values from LINEQX and LINEQY. ) and LINEQY are placed in the calculator?s list editor, unless the list editor is full. LINEQX Inequality Graphing for the TI-83 Plus Page 31 Storing points is not limited to the PoI-Trace mode or to points of interest. You can also manually add values to LINEQX and LINEQY, although there is one specific limitation: both lists must contain only real numbers. Both lists must contain the same number of elements for Inequality Graphing to store points to them. The first point found is displayed. Inequality Graphing for the TI-83 Plus Page 32 2. Press to store the coordinates to LINEQX and LINEQY. If (LINEQX, LINEQY) already contains the point you want to store, a message displays. At least two inequalities must be defined and selected in order to shade the inequality intersection. At least two relations (equations or inequalities) must be defined and selected to shade the union. Inequality Graphing for the TI-83 Plus Page 41 Inequality Graphing Error Messages Message ERR: MEMORY 600 Bytes Free RAM Needed 1: Quit Inequal Conflicting APPS 1: Quit Inequal 2: Quit Apps listed below ERR: INEQVAR 1:Overwrite 2:Quit Inequal Description The calculator does not have enough free RAM to create the INEQVAR AppVar. One or more applications that are currently running use the same resources as the Inequality Graphing application. To run the Inequality Graphing application, you must quit the conflicting application(s). An AppVar named INEQVAR already exists, but it is not related to this application. Select one of the following options: 1:Overwrite to overwrite the current AppVar. 2:Quit Inequal to quit the application. Inequality Graphing will not run without the correct version of INEQVAR. You must either rename the existing AppVar or let Inequality Graphing overwrite it. ERR: Data Type 1: Quit 2: Goto An X-variable (in the X=editor) evaluates to a number that is not real. Select one of the following options: 1: Quit to restore the previous value for that X-variable. 2: Goto to change the X-variable so that it evaluates to a real number. Inequality Graphing for the TI-83 Plus Page 42 Message ERR: Divide by 0 1:Quit 2:Goto Description You have entered an expression on the Y=Editor or X=Editor that is divided by zero.
