is selected, R and q are displayed.

TRACE
To activate TRACE, press r. When TRACE is active, you can move the trace cursor
along the graph of the equation one q
step at a time. When you begin a trace, the trace
cursor is on the first selected function at q
min. If ExprOn format is selected, then the
equation is displayed.
In
RectGC format, TRACE updates the values of X, Y, and q; if CoordOn format is
selected, X, Y, and q are displayed. In
PolarGC format, TRACE updates X, Y, R, and q; if
CoordOn format is selected, R and q are displayed.
To move five plotted points at a time on a function, press y| or y~. If you move
the trace cursor beyond the top or bottom of the screen, the coordinate values at the
bottom of the screen continue to change appropriately.
