Thanks for your reply! Is there any possibility to find a workaround
here? Or maybe to report it as a bug? I know for sure that this
function can be plotted, see here:
http://dl.dropbox.com/u/1507406/Determination%20of%20cosmological%20parameters%20for%20non-specialists.pdf
(Figure 1 on the 3. page). Also there is another representation of
this function which doesn't contain a 1/z term and still fails in
Maxima (it's equation 3.9, whereas the original expression is equation
3.6).
Thanks again,
Michael
