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:
• We will generate values of the function f(x), defined above, for values of
x from –5 to 5, in increments of 0.5. First, we need to ensure that the
graph type is set to

them simultaneously, if in RPN mode). The field in front of the Type option
