[sage-support] Mathematical Expression to latex-code-conversion

2007-10-24 Thread marko
Hello, I am quite new to SAGE but I think I've found a problem with the latex(math-expression) command. I've tried with version 2.8.6, 2.8.7 and 2.8.8.1: The problem seems to be the abs() command. Take any function like f(x)=2*abs(x) with a changing sign. Entering now latex(f) shows me as the

Hello, I've fixed this issue and have included the patch below. It will be in the next release which should be come out in the next few days. Here is the behavior after the patch: sage: g(x) = 2*abs(x) sage: latex(g) x \ {\mapsto}\ {2 \cdot \left| x \right|} --Mike

[sage-support] solve problems

2007-10-24 Thread Marshall Hampton
I was going to work on the sage wiki's teaching page for linear algebra, but I got stuck on my first attempt at porting a problem. The problem was to study the two by two solutions to A^2 = I; in one of my classes I have students work on that for a day on paper and then let them use Mathematica

[sage-support] An interactive 2D/3D environment for SAGE

2007-10-24 Thread Ted Kosan
For the past couple of months, I have been researching strategies for extending SAGE with an interactive 2D/3D environment that would be significantly more advanced than what current mathematics software provides. My vision is to be able to place the user into a 3D environment where they can

[sage-support] Odd integration

2007-10-24 Thread kcrisman
We're on symbolic integration techniques in my Calc II class right now, and SAGE rather nicely deals with many (but not all) of the standard examples, or makes the usual mistakes various other systems make (e.g., integrate(1/x) gives ln(x), not ln(abs(x))). However, I'm stumped as to where this
