•The split screen is always in the trace mode. Therefore, the cursor pointer appears on the graph. Accordingly, the coordi- nate values are displayed reverse in the table and in the equation at which the cursor pointer is located is also displayed reversely.

•Using ;or ', move the cursor along the graph. (Values displayed reverse in the table are also changed accordingly.)

•When two or more graphs are displayed on the screen, the desired graph is selected using {or }. (The table or equation on the right of the screen is also changed accordingly.)

•The table on the split screen does not relate to the table settings on the full-screen table.

•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 full-screen table is displayed by pressing T, 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 to be graphed are displayed on the split screen.
