3.2 Discussion


  Graph2D is able to do a complete discussion for real functions with max.
one argument.

  Before the discussion Graph2D asks you with a requster to edit the
test-intervall in which the discussion should be done. That test- intervall
should alway be choosen as small as possible, because the wider you chose
it the worse is Graph2D in detecting the points of the function you are
looking for. The result of every search will be outputted in a  textviewer
and may even be send to a printer from there.

  A complete discussion consists of the following parts, which can also be
executed allone from the  function-editor:

  3.2.1   �Zero-points����
  3.2.2   �Extrema��������
  3.2.3   �Turning-points�
  3.2.4   �Monotony�������
  3.2.5   �Symmetry�������

  A dicussion may take (especially on 68000er Amigas) sometimes quite a
long time and it is also very recommended to verify the results by having a
look to the graph of the function. So you probably will see soon, that
certain types of zero-points will sometimes really not be detected.
