Generating a table of values for a function | HP 49g guide

VIEW, then press @AUTO to generate the V-VIEW automatically. The PLOT WINDOW screen looks as follows:

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

•To see labels: @EDIT L@LABEL @MENU

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

•To trace the curve: @TRACE @@X,Y@@ . 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 = 0.0231. Also, check that for x = -1.48 , y = 0.134. Here is picture of the graph in tracing mode:

•To recover the menu, and return to the PLOT WINDOW environment, press L@CANCL. Press L@@OK@@ to return to normal display.

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:
