bracketssubscriptssuperscripts
I want to write like this:
But when I write
\documentclass{article} \usepackage{mathtools} \begin{document}
\begin{equation}
\lim\limits_{\Delta\rightarrow0}\Delta{}_{t=0}^{t=T}\left\vert\dfrac{df(t)}{dt}\right\vert^2
dt \end{equation} \end{document}
The output was like this
Anyone can tell me what is my mistake?
There are many tools for scripts:
For general math scripts before something, use \prescript provided by mathtools package, for better alignment:
$ \prescript{14}{2}{\mathbf{C}} $
For large operators, use \sideset from amsmath:
$ \sideset{_a^b}{'}\sum A_n $
For chemical equations, use mhchem package:
\ce{^{227}_{90}Th+}
For tensors, use tensor package:
$ M\indices{^a_b^{cd}_e} $
$ \tensor[^a_b^c_d]{M}{^a_b^c_d} $
Please complete this list as you can.
The visual result:
The slight difference is in the fact that TeX uses "cramped display style" when typesetting the argument to \widehat, which is characterized by reduced lowering of subscripts and raising of superscripts.
This is one of the cases where TeX needs help; here's a way:
\documentclass{article}
\usepackage{mathtools}
\begin{document}
\[
\cramped{\mathbf{L}_\mathbf{s}}
\widehat{\mathbf{L}_\mathbf{s}^{+}}
\]
\end{document}
Alternatively, don't let the wide hat cover also the superscript and subscript:
\documentclass{article}
\begin{document}
\[
\mathbf{L}^{}_\mathbf{s}
\widehat{\mathbf{L}}_\mathbf{s}^{+}
\]
\end{document}
Notice the empty superscript.

The
_{t=0}^{t=T}in your line makes these things the superscript and subscript of the\lim\limits_{\Delta\rightarrow0}{}. I would do it using\prescriptfrommathtoolspackage.and then in the math environment:
This provides the result as follows:
