Hello,
I've tried looking at all the plot options in the documentation, but I
can't find how to do the following. Maybe someone can help...
* control over the scaling of the y-axis. I can choose xmin and xmax,
but the range of the y-axis is always chosen automatically.

Hi Maike,
I found that the use of pylab allows a lot more control over your
plots. Example:
import pylab
x1 = srange(0,1.1,0.01)
d1 = [2*x+x^2 for x in x1]
d2 = [3*x+0.9*x^2 for x in x1]
title='Test plot'
pylab.clf() # clear the figure first
pylab.figure(1)
# plot some data and add a legend
pyla
I have a worksheet "Getaltheorie" in my Worksheet List. When i give
the command attach Getaltheorie (or attach 'Getaltheorie', or or
attach 'Getaltheorie.sage' or ...) in another worksheet, i get the
error message 'Error attaching /Users/jokr004/.sage/Getaltheorie --
file not found'. I'm sure I'
Dear all,
When I upgraded to 3.1.2, I found that some of my plots generated
using pylab in the notebooks miss their bottom bits. It seems to be
related to the dpi setting. Example:
import pylab
x1 = srange(0,1.1,0.01)
d1 = [2*x+x^2 for x in x1]
pylab.clf() # clear the figure first
pylab.figure(1
I can confirm this bug and opened

Cheers,
Martin

Since upgrading to 3.2.1, the following does not work any more:

I am brand new to this. I was wondering how to calculate mods while in
the sage notebook. I need to calculate 520622^430085 mod 998171. Does
anyone know how to type this into the command line. I keep getting a
syntax error. I have no idea how to do this because I am brand new to
sage. Thank you.
sage: 520622^430085 % 998171
897985
It is very much faster to do it more like this:
sage: R=Integers(998171)
sage: a=R(520622)
sage: a^430085
897985
The first way (I think) computes 520622^430085 as an integer and then
reduces, while the second way constructs the ring of integers mod
998171, de

Thanks!!
A more general question, how can I find out all the possible options
for a command, like "show" for example?
I've tried show.option? which doesn't seem to work.

Or, if you want to do it in a single line (which does the same as the
more explicit code below)
sage: mod(520622, 998171) ^ 430085

To add to Stan's reply, you can add
pylab.grid(True, linestyle='-', linewidth=.5, alpha=.3)
in order to have a light grey grid display at the background.

in http://www.cosc.canterbury.ac.nz/greg.ewing/python/Pyrex/ there is
the following example:
def primes(int kmax):
cdef int n, k, i
cdef int p[1000]
result = []
if kmax > 1000:
kmax = 1000
k = 0
n = 2
while k < kmax:
i = 0
while i < k and n % p[i] <> 0:
i = i + 1

Yes, I could read a few hundred pages of manuals, but how hard should

Yes, I saw that in the solution of the other one (and have changed my
plots to take this into account), but what is the advantage of the
aspect ratio default *not* being 1? I'm very curious. I'm not a
mathematician, just a student going through college, so I would love
to hear the why behind this.
If c=sqrt(a^2+b^2)
How would I check if c is an integer in order to get a true/false
value.
I tried is_Integer(ZZ(c)), this returns true when c is an integer, but
ZZ(c) returns an error when c is not an integer.
