Thanks a lot!. This work for the special case of myHH, where:
myHH(t) =(1-e^(-t/0.1))^3*(e^(-t/10.)
However, for a more general function:
sage: t=var('t')
sage: taum, tauh, m = var('
Dear Sage mailing list
I am having a hard time to get the maximum value
(numerically/analytically) to one equation. In concrete I want to solve:
sage: t= var('t') # dependent variable
sage: taum, tauh, m = var('taum, tauh, m') # parameters
sage: f(t) = ((1-e^(-t/taum))^m)*(e^(-t/tauh))
Now i

Hi everybody,
To become familiar with ODEs with Sage, I am trying to solve a very simple
ODE with the Laplace method implemented in Sage
In concrete, i want to solve
dy(t)/dt = -k*y(t)
with for example
ith different values of k
>>> fig1 = plot(mysol.subs(k=1/5.), 0, 10)
>>> fig2 = plot(mysol.subs(k=1/2.), 0, 10)
Of course, for more complex ODEs
Thanks a lot in advance.

When importing line3d from a sage session with IPython as interpreter,
I've got the following error message:

I am starting to collect lots of sage notebooks and I was wondering if
is there any way to store the in different directories.
Thanks a lot in advance.

but I was wondering if there was something like sageenv around, and how
to use,
Thanks a lokt, kcrisman, for your comments :P

Hi everybody,
I've just installed Sage 4.6 from the sources and wondered how could I
call the executable $HOME/sage4.6/sage from any directory within my
$HOME. What do you guys write in .bashrc to access the executable?
Thanks a lot in advance
