In the command line you can give a command with administrative powers
by writing sudo before it, for examle
sudo mkdir /myfolder
will create a folder in the system root (something which requires
admin powers). You must be carefull when using sudo, since you could
damage your system if you give a
One last thing, Is there some way to calculate the correlation index
(R^2) of the fit in sage?
thanks!

Thank you very much, that worked perfect. Though I must say I expected
not having to determine the period myself. I thought find_fit would do
that for me. This way all it does is refine my estimate. But thanks
again.

ahh that may explain it
also i found a way to get the last itteration out of the loop
by setting
for...
ak=...
ad=ak
print ak

okay, i got that now, but then how do i take the final ak (adegree) out of
the loop and recognise that ak from further on

it only prints a0 and ignores the for loop
how can

It's very hard to tell with the "extreme" indenting you are using, but
