I have found my mistake - I had 'maple' selected by accident in the
fourth menu to the right, at the top of the notebook page. Now it
works as you indicated, without the error appearing.
Thank you again.

There seemed to be something odd about the cut-and-paste on that last

I enter this line at the Sage prompt:

I suggested a little change.

Perhaps I spoke too soon... the numerical_integral command does not
seem to work on my installation either - once again it appears to

Maple? The numerical_integral command certainly does not use Maple.
It just uses the GSL C

Thank you very much, your reply was very helpful. I did not know about
the numerical_integral command.

If that is the sort of plot you are after, would it be easier to just
generate it directly from Sage? Becaus

Hello,
I'm new to Sage and this group.
I have been doing some simple experimentation with integration in

calculate an integral, attempting to reproduce the problem described

I still have no idea what a .dat file is. If it's plain ascii, or a
simple binary format, I'm sure Sage could do it with little difficulty.

Basically, it is a way to display covariance. You build a model based
on covariance which may help to explain cause and effect. Of course,
you have to design the model very carefully and
