Hi there!
Have just found a strange phenomenon. Firstly, write the following
double integral:
'integrate( (A-r)*w^(R-1) - 'integrate( (u-1)^(R-1)/u^R, u, 1,
w ),w,1,W);
The inside with the (1-1/u)^(R-1) term is horrible - I don't think it
can be done analytically, but there is clearly another term which
maxima should cope with happily.
Evaluating with
%, nouns
Does nothing helpful, but if you type
'integrate( (A-r)*w^(R-1), w, 1, W);
and then evaluate with
%, nouns
you get the expected integral.
Is this behaviour expected? Is there a way around it? Here's the
banner, by the way:

Hopefully someone can shed some light? :)
