Hi:

I think this question is better posed on sage-support, which I am cc'ing.
sage-edu is about teaching with SAGE.
Am I correct in assuming you have a parameterization of your
line integral (with parameter q) and so you can write the
contour integral as
int_a^b f(q) dq
after some substitutions? I'

If you are a SAGE developer, could you please reply to this list (or just

BTW, I used several Barnsley ferns in Sage, GIMP and inkscape to create this

The Barnsley fern code is here:

sage: R. = PolynomialRing(IntegerModRing(5),"x")
sage: f = 1-x+6*x^5; f
x^5 + 4*x + 1
Type "PolynomialRing?" for more examples.
(This is more of a question for sage-support than sage-edu.)

I agree, some consistent syntax for multiple integrals is needed.
For example, to me this seems strange:
sage: x,y = var("x,y")
sage: f = y*sin(x*y)
sage: bool(diff(f,x,y) == diff(diff(f,x),y))
True
sage: bool(integral(f,x,y) == integral(integral(f,x),y))
False
At least, it is a possible source
a default value for the
number of samples used to create the plot.
Anyway, what Sympy has implemented currently is similar to what I was

Very nice! What about symbolic constructions? For example,
sage: A = matrix([[x,1],[sin(x),e^x]])
sage: A.det()
x*e^x - sin(x)
sage: f(x) = A.det()
sage: f(pi)
e^pi*pi
Should they be added?

I have to confess I don't understand your question. In case you are asking about
folders for the notebooks (so you can put different groups of student's
worksheets in them, for example), then that is not yet completely
implemented, as far as I know. I think Mike Hansen is working on it
in the Sage

This is the list for using Sage in education.
Perhaps the FAQ http://wiki.sagemath.org/faq might help or
the REDME http://www.sagemath.org/bin/microsoft_windows/README.txt
If not, maybe you could search the sage-support archives (see the
search box on the main Sage page) or email sage-support you
Hi William:
Is the latex source for the lecture notes referred to at
http://wiki.wstein.org/2008/480a available? I hope to be
teaching Coding theory and Python next semester, with
a significant amount of Python in the course. You notes
seem like a good place to start.

Do you mean this?
sage: n = 1234567890123456789
sage: len(str(n))

I don't know the answer, but maybe this is a way around it:
sage: 23/10 in srange(3, step = 1/10)
True
You might also use this is discuss how numbers are represented
in a computer (leading into how characters are represented in a
computer., which might also spark an interesting class discussion.
