var('y', domain='real')

e^(1.1*I*y)
The last result is incorrect. It seems simplify() doesn't like
floating point?
Thank you

You can always just install any linux into virtualbox and install Sage
Additional note: There is also a tutorial available to install Sage in
Wubi (Ubuntu Linux on Windows partition)
In case anyone missed it, there is now a virtualbox image for 4.2.1 up
on the mirrors.

I think that's not true, there is guest smp since virtualbox 3.

Thanks everyone for all of your help and advice!
I just showed my boss how I used ode_solver/sage/python to model and
fit some tricky chemical kinetics data, and needless to say, she was
very impressed.
I'm thinking this ode_solver function will be quite useful for our lab
in general. If I play

For more options,
No offense but all of your examples would be a _lot_ easier with
biopython, which is a pretty mature and well-tested codebase for doing
all sorts of bioinformatics in python. I really recommend you look at
its tutorial if you haven't yet:

Dear support,
I'm giving a talk Wednesday and would like to do the following

y = function('y',x)
f = desolve(diff(y,x) + g, y, ics=[2,2])

You probably also want to do something like
P=plot_slope_field(-g,(x,0,3),(y,0,20))
since the slope of the solution is -g, not g.

It looks like you are confusing y-as-a-variable and y-as-a-function an
awful lot. How about:
Yes, because I was hoping to make it as easy as possible to switch
from the static version. Unfortunately, this isn't that :( but it's
probably the best we can do?

Yeah, there was a typo of + for -.

How serious is the following message?

William,
I'm curious -- what in particular is broken about GAP-4.4.10? We
tried to ship 4.4.12, but found it to be more broken; in particular,
it didn't work on Itanium Linux boxes, which is one of our officially
supported platforms.
I tried to reproduce your problem on an Itanium cluster at
