•Plot the graph: @ERASE @DRAW (wait till the calculator finishes the graphs)

•To see labels: @EDIT L@LA EL @ME U

•To recover the first graphics menu: LL@)PICT

•To trace the curve: @TRACE @@ @@ . Then use the right- and left-arrow keys (š™) to move about the curve. The coordinates of the points you trace will be shown at the bottom of the screen. Check that for x = 1.05 , y = 0.0131. Also, check that for x = -1.48 , y = 0.034. Here is picture of the graph in tracing mode:

Generating a table of values for a function

The combinations „õ(E) and „ö(F), pressed simultaneously if in RPN mode, let’s the user produce a table of values of functions. For example, we will produce a table of the function Y(X) = X/(X+10), in the range -5 < X < 5 following these instructions:
