Hi All,
I'm running Sage 4.2 on Ubuntu 9.04. I installed it by downloading the
tarball, compiling and installing into my home ~/ directory.
Everything seems to work fine. Maxima is doing Laplace transforms, and
I'm seeing the correct output with the LaTeX interpreter. I'm working
through the tutorial on differential equations, and have reproduced
the 3rd DE example of two coupled mass/springs perfectly - including
the plots.
However, I can't reproduce the output shown in the first example.
Code:
t = var('t')
x = function('x',t)
DE = diff(x, t) + x -1
desolve(DE, [x,t])
print x
print DE
Output:
x(t)
x(t) + D[0](x)(t) - 1
According to the tutorial, the output for "print x" SHOULD be:
(c + e^t)*e^(-t)
Am I missing a library or something? Any clues/links on where to start
would be much appreciated.
Yar
