I believe that the caclulator lost some digits in
there. If you go into table mode and look at a graph
with a horizontal asymptote, it may so past that
number a bit, then return, and just act strange. An
example of this is to graph sin(99<theta>) on the
standard graphing window and change <theta>-step a bit.
