Do you mean you executed this in a Sage cell? That would

Since there may be other inconsistencies between browsers, it seems
safer to just have all students use Firefox. That is fine with me. I

Thanks. Yours command work :)
I used
from sage.misc.latex import latex_extra_preamble
latex_extra_preamble()
'\\newcommand{\\floor}[1]{ \\lfloor #1 \\rfloor}'
which I found in the standard documentation. And it does not work.
Perhaps, someone can check whether it is a bug.

Is it possible this is an older version of IE? Unfortunately, IE uses
completely different javascript ideas, or so the experts tell me. I'm
not sure there is a short-term solution to this.

Hello, i think that my question is simple one, but i have not found
answer in the reference manual. I need a function of vector variables.
For example:
var("x1,x2,x3")
x=vector([x1,x2,x3])
Is it possible to define a function of the vector variable "x",
something like this: f(x)=sum(x[i]*x[i]for i i
