A.X=0 \Longleftrightarrow

\[M(A)=\left(

4&-2\\
5&-3\\



\left(

Good evening

My future vocation is to be an astrophysicist.

Would like to know what are the graphical possibilities of laTex.

Can we do mathematical graphs?

Make drawings?

See you soon.

Thank you very much !

Sorry for my inattention.

See you soon...

good evening

I almost arrived there, it misses the lines of the table.

$det(B)=$
\begin{tikzpicture}[baseline = (m-2-2.base)]
\matrix (m) [matrix of math nodes,
row sep = .5em, column sep = .5em,
every node/.style = {anchor = base east}] {
\ 1 & 1 & 0 & \ 1 & 1 \\
-1 & 2 &-1 &- 1 & 2 \\
-1 ...

good evening

There is one more problem.

Here is the code below.

$det(B)= $

\begin{tikzpicture}[baseline = (m-2-2.base) ]
\matrix (m) [matrix of math nodes,
row sep = .5em, column sep = .5em,
every node/.style = {anchor = base east}] {
1&1&0&1&1 \\
-1&2&-1&-1&2 \\
-1&-1&3&-1&-1 \\

Good evening

I would like to realize a LaTex page with the calculation of the determinant of a matrix with the rule of Sarrus.

I found this tutorial.

https://tex.stackovernet.com/fr/q/103579

It does not work, I get lots of mistakes.

On my computer I have MikeTex.

See you soon
