Hello,
I believe I found a bug in how radicals are simplified. The general
idea is that sqrt(x^2)=abs(x), but sage simplifies sqrt(x^2) to x instead,
even if x is negative. I've included a simple example below.
sage: x = var('x')
sage: assume(x<0)
sage: expr = sqrt(x^2)
sage: simp_expr=e
I want to create a plot by traversing a tree where some leaves of the data
structure add line segments. I am trying to pass one graphics object to a
function that adds a line segment to the graphics object. I assumed the
graphics object is passed by reference so that changes inside the function
stalled:
$ dpkg -l |grep mpc
ii libmpc-dev 0.8.2-1+b1
multiple precision complex floating-point library development package
ii libmpc2 0.8.2-1+b1
multiple precision complex floating-point library

Sorry, I was not able to attach the full log file gcc-4.6.3.log. Please
find below the most relevant parts of it.

Please find attached the log file. FYI, I am using Debian GNU/Linux running

Thanks for your help!

I'll look up the maxima manuals to see if I can force it to think
harder. Thanks anyway!
Have a nice day!

wards induction), but
maxima fails (line -2) with simplifying after the substitution is
made, even though the substitution is successful (line -3).
I expect to receive the line in the last "paragraph" as defined by
D1p.
Is this a bug or did I made a mistake?
