My question is a like the one here: only with different symbol.
With typing: \[\^{\i}\]
i want to get a get a i with a ^ (replacing the dot) on its head.
So far, so good. Means it works (i get the symbol i wish to get) but TeXstudio (Version 2.12.10 (git 2.12.10)) gives me two warnings also:
Command \^ invalid in math mode
and
Command \i invalid in math mode
The command \hat{i}
gives me an i with a ^ ontop. That is not excactly what i want.
The solution with $\o$
replaced by \varnothing or \Emptyset
seams to be the same, well maybe i'm just searching for the right word for my symbol in question?
Any suggestions?
Update 1 after getting a solution form @Henri Menke
(On the left side of the equation)
The left one is the result of \hat{\imath}
result, \cdot
, the right one it the result of \^{\i}
With other words:
Lets assume that \hat{\imath}
is indeed the right symbol, than i have to write \(\hat{\imath}\)
(with math enviroment) every time i need to use it in my text for reference?
Update 2 I knew that link before asking my question but it wasn't helpfull in my case. Maybe have a look here, for looking up other unknown symbols if you have a "similar" question (Please credit him if it helps you)
Best Answer
You can access the dotless version of i and j in math mode using
\imath
and\jmath
.
