Appendix B: Technical Reference 916
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.
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.
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.
Note: For a complete description of these settings, refer to “Formats of Displayed
Results” in the Operating the Calculator module.
1 Only one part can display graphs.
2 Both parts can display an independent graph
screen (Graph or Graph 2 setting) with
independent settings.
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.
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.
