TI-83 Plus Sequence Graphing 189
Exploring Sequence GraphsFree-Moving Cursor
The free-moving cursor in Seq graphing works the same as in Func
graphing. In RectGC format, moving the cursor updates the values of X
and Y; if CoordOn format is selected, X and Y are displayed. In PolarGC
format, X, Y, R, and q are updated; if CoordOn format is selected, R and q
are displayed.
TRACE
The axes format setting affects TRACE.
When Time, uv, vw, or uw axes format is selected, TRACE moves the
cursor along the sequence one PlotStep increment at a time. To move
five plotted points at once, press y ~ or y |.
• When you begin a trace, the trace cursor is on the first selected
sequence at the term number specified by PlotStart, even if it is
outside the viewing window.
• Quick Zoom applies to all directions. To center the viewing window
on the current cursor location after you have moved the trace cursor,
press Í. The trace cursor returns to
