I don't know if you are asking about how to use ICs in
desolve or if you are asking about how to do substitutions.
Anyway, I get this:
sage: y=function('y',x)
sage: desolve(diff(y,x)+sin(x)*y^6==0,y)
1/(5*y(x)^5) == c - cos(x)
sage: desolve(diff(y,x)+sin(x)*y^6==0,y,[pi,9])
1/(5*y(x)^5) == (-295

I don't understand the question. Do you want a contour plot? An implicit plot?

I think this is with y = 1/4:
sage: h = Piecewise([[(0,1/4),3*x/4],[(1/4,1),(1-x)/4]])
sage: h.plot()

Done.
BTW, I noticed that the download link sends one to a page
for a mac binary but there is no binary on that page,
only a README.txt file. Is that intentional?

Another is to try to precompute the hessian and pass it into your

The answer really depends on if your server is on an intranet LAN
(inaccessible from
the rest of the world) or on a (public) internet web server. In the
former case, the answer
is very easy and even I can answer your question!

Perhaps you could convert this into a system of linear equations then
use the solve command?

Hi:
There is a fairly polished book on differential calculus and Sage
now available at amazon.com
http://www.amazon.com/gp/product/1448662192/ref=pe_5050_12929060_snp_dp
(Hope that url works for others - if not just search amazon for the title.)
All royalties go directly to the Sage Foundation. H

There is the GAP stuff, lots of native stuff (use the search bar on the
main Sage webpage), and lie is an optional package. What is it that you want?

Thanks. I consider this a bug though it might be
more precisely described as an unimplemented feature
(I'm guessing that there is no __mul__ method in the appropriate
class). Until it gets fixed, here is a workaround:
sage: f = maxima.function('x', 'sin(x)')
sage: g = f.integrate("x")
sage: h = m
