Hi,
I need a command which separate the components of points. For example

Could you please help me?

Do you use anything that may affect sage's ability to open ports?
My problem with answering is that I don't really know anything about

Am I missing something or is this behavior rather peculiar:

I tried it and received wrong answer.
Let's consider for example the code:

forget()
var(a,b,c,d,f)
assume(a-b0)
expr=(a^2-b^2)*f
expr2=sqrt(expr)
print(expr2.full_simplify())

It gives
sqrt(a - b)*sqrt(a + b)*sqrt(f)
But a-b0, so expression

Does Sage have a command to get the mirror image matrix
[3,2,1]
[6,5,4]
from the matrix
[1,2,3]

Like this?
sage: m = Matrix([[1,2,3],[4,5,6]])
sage: m
