The available application choices are those listed when you press B from the Page 2 mode screen or when you press O. You must have different applications in each screen unless you are in 2-graph mode. Number of Graphs Specifies whether both parts of a split screen can display graphs at the same time. 1 Only one part can display graphs. 2 Both parts can display an independent graph screen (Graph or Graph 2 setting) with independent settings. Graph 2 Specifies the type of graphs that you can plot for the second graph on a two-graph split screen. This is active only when Number of Graphs = 2. In this two-graph setting, Graph sets the type of graph for the top or left part of the split screen, and Graph 2 sets the bottom or right part. The available choices are the same as for Graph. Split Screen Ratio (Voyage 200 only) Specifies the proportional sizes of the two parts of a split screen. 1:1 The screen is split evenly. 1:2 The bottom or right part is approximately twice the size of the top or left part. 2:1 The top or left part is approximately twice the size of the bottom or right part. Exact/Approx Specifies how fractional and symbolic expressions are calculated and displayed. By retaining rational and symbolic forms in the EXACT setting, the TI-89 Titanium / Voyage™ 200 increases precision by eliminating most numeric rounding errors. 1:AUTO Uses EXACT setting in most cases. However, uses APPROXIMATE if the entry contains a decimal point. 2:EXACT Displays non-whole-number results in their rational or symbolic form. 3:APPROXIMATE Displays numeric results in floating-point form. Note: For a complete description of these settings, refer to "Formats of Displayed Results" in the Operating the Calculator module. Appendix B: Technical Reference 916
