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(x0)
sage: expr = sqrt(x^2)
sage:
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

Hi,
I'm fairly new to sage with some background in maxima.
My workbook is shared at

the last three lines show the error I get.
Basically, I derive an equilibrium
This is exactly what I wanted. 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!

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?
Thanks for your help!
