Hi,
is there an efficient way in sage to find the smallest integer k to
meet (b constant)
b^(k+1) / (factorial(k) * factorial(k+1)) = 1
and
b^k / factorial(k) =1
or, more generally (b, c, d positive constants, c d)
b^k / (factorial(k) * (k + c - d)^d) = 1
many thanks in advance, Georg
Apologies if this is double-sent; I thought I sent it already but
don't find the submission.
Suppose I have a discrete function, as at the bottom (in this case a
frequency distribution).
Does anyone have a good example for producing a bar graph? Ideally I
would like both latex
and some
This question was just asked by someone else on sage-newbie.
In gsl/dft.py there is a plot_histrogram function. Other people
suggested other options in the htread though.

Excuse me, i'm not a native english speaker (and i thought i read this
mode of speaking somewhere before):
is there an efficient way in sage to find the smallest integer k for
which the inequality
b^(k+1) / (factorial(k) * factorial(k+1)) = 1
is true (b 0)
similarly for
b^k / factorial(k)
Georg,

which the inequality
b^(k+1) / (factorial(k) * factorial(k+1)) = 1
is true (b 0)
Stirling's expansion gives (when b goes to infinity) k ~ sqrt(b)*exp(1).
Thus it suffices to evaluates f(k) = b^(k+1) /
Oh yeah, that's a usefull hint,
thank you very much Paul,
Georg

can i read/write data from external files ?
can Sage process text ?
Yes
Sorry for replying my own email, but I just started tinkering with
Python's wave module:

I'll try to report my progress.

Best,
Sage also has some wav processing support that is built on
