I had to create a cover using the "easy" option, so it is a different looking

Dynamic Sage notebooks are really amazing.
I'm also an R user and I would like very much
to use sage to create notebooks with statistical examples
in R . Is this possible?
By the way , I thought it was allowed to execute
R code within an R notebook.
However I tried to change the interpreter to

Hi there,
just started using SAGE for some research related stuff a couple of
weeks ago. Is there a way to get the conjugacy classes of a group, in
the same way as GAP does? I don't quite mean neither
"conjugacy_classes_subgroups" (which returns conjugacy classes of
subgroups, not of elements) no
I suspect that these are simple questions, but need help getting
started. Thank you!
How do I exhibit coefficients of the unique cusp form of weight 9/2,
level 4 and trivial character?
(The coefficients should be 1, -6, 12, -8, 0, 12, -48, 48, -15, ...)
How do I compute the dimension of the spa

Hello,

a similar question is answered in the Python FAQ:

I need to solve a very simple equation x^2 + 1 = 0 and I don't want
any complex solutions.
I tried this
x = var('x')
assume(x,'real')
solve(x^2 + 1 == 0)
but the output is [x == -1*I, x == I]
Does exist any solution in order to avoid this ?

Hi there
I am trying to teach some simple principles of single compartment models
with sage and I plotted a couple of exponential equations in my notebook.
Although I got a nice x-axis () and other labels and similar things, I
cannot find a way to plot the y-axis in the vertical axis. Is there
