Tool „ Zoom ... Trace ‡ Math For Sequence Graphs: Works just as it does for function graphs. • Only x (xmin, xmax, xscl) and y (ymin, ymax, yscl) Window variables are affected. • The n and plot Window variables (nmin, nmax, plotStrt, plotStep) are not affected unless you select 6:ZoomStd (which sets all Window variables to their standard values). Depending on whether you use TIME, CUSTOM, or WEB axes, Trace operates very differently. • With TIME or CUSTOM axes, you move the cursor along the sequence one plotstep at a time. To move approximately ten plotted points at a time, press 2 B or 2 A. - When you begin a trace, the cursor is on the first selected sequence at the term number specified by plotstrt, even if it is outside the viewing window. - QuickCenter applies to all directions. If you move the cursor off the screen (top or bottom, left or right), press ¸ to center the viewing window on the cursor location. • With WEB axes, the trace cursor follows the web, not the sequence. Only 1:Value is available for sequence graphs. • With TIME and WEB axes, the u(n) value (represented by yc) is displayed for a specified n value. • With CUSTOM axes, the values that correspond to x and y depend on the axes you choose.
