I never have any luck with plotting in Sage. The simplest plots fail.
For example the following
plot(20*log(abs((1+I*x)^4+4),10),(x,0,3))
fails with
TypeError: float() argument must be a string or a number
I don't see what's wrong with it.

Dear Mike,
Thanks! A real gift.
I wonder how I could find such a solution myself?
That is my only, but serious, problem with Sage. Where to find an
adequate solution for a problem> Hopefully this will be solved in the
comming years. For instance via an expert system.

gg.factor().unit() should give it to you.

Hi Roland,
You can try gg.operands(), which gives me
[A^3, 4]
Hope this helps,

Hi,
gg=4*A^3
gg.factor()
(4) * A^3
How to separate the number 4? Nor gg.dict() nor list(gg.factor()) has
the number 4.
Remarkable is also the output of gg.factor()/4: (4) * 4^-1 * A^3

The problem here is not that Sage messes up the notebooks, even in a
big, bad way; that can happen with any software.
The problem is that, even though I have made manual backups, it's
going to take hours of work to fix it.
And it takes

Well, I still have a backup file with worksheets that are a couple of
