I have this tex: \(\mu_{A}\left(x\right)\in \[0,1 \right\]\)

The issue here is that [ and ] are not showing around 0,1, why is that?

    I guess you are using latex (you didn't say) and that you got an error message (you didn't say that either). \[ in latex is a command to start display math, to get a [ just use [ also you need \left on the [ or (better) don't use \right with the ] – David Carlisle Dec 3 '13 at 17:00

    \[0,1 \right\] is wrong, simply [0,1] – karlkoeller Dec 3 '13 at 17:00
  • @David Carlisle. Thanks for your reply. Yes, you are right, I'm using LaTex. I didn't get an error message, just didn't get the expected result – Simplicity Dec 3 '13 at 17:09
  • You _must have got an error message, I will update my answer. – David Carlisle Dec 3 '13 at 17:21

enter image description here



\(\mu_{A}(x)\in [0,1]\)


If you change the expression to the one in your question then you get the error message

! LaTeX Error: Bad math environment delimiter.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

l.5 \(\mu_{A}\left(x\right)\in \[
                                 0,1 \right\]\)
? h
Your command was ignored.
Type  I <command> <return>  to replace it with another command,
or  <return>  to continue without it.

where the linebreak after \[ indicates that is how far TeX had got before issuing the error.
