Building your own table of numbers
The default NUMTYPE is “Automatic”, which fills the table
with data for regular intervals of the independent (X, T,
θ,
or N) variable. With the NUMTYPE option set to “Build
Your Own”, you fill the table yourself by typing in the
independent-variable values you want. The dependent
values are then calculated and displayed.
