I want to make wide parentheses and symboles like them. I used yhmath package in my file and It worked correctly. But when I use the bigints package in my file too everything will break down. I mean the size of my integrals is not big.
Who smells rat?
I studied yhmath package and saw this command:
\DeclareSymbolFont{largesymbols}{OMX}{yhex}{m}{n}
This command has its side effect on the bigints package and delimiters which are in the ams package too.
How can I use both of (bigints&yhmath package) together and where can I study about commands like below?
\DeclareSymbolFont{largesymbols}{OMX}{yhex}{m}{n}
\DeclareSymbolFont{operators}{OT1}{txr}{m}{n}
\DeclareMathAlphabet{\mathbf}{OT1}{txr}{bx}{n}
Thanks for your responsibility.
This is my example file:

\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{yhmath}
\usepackage{bigints}
\newcommand*\diff{\mathop{}\!\mathrm{d}}
\begin{document}
\[\wideparen{abcggg}\quad \widetriangle{abc}\quad\widering{abc}\]
\[\bigintsss_0^5{x^3}\diff{x}\]
\end{document}

The yhmath package loads the math extension font at a fixed size. You can make it scalable. However, I'm recommending not to use bigint: variable size integrals are not really nice.

I've also redefined \widering as the default definition is disputable.

\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{yhmath}
\usepackage{bigints}

\DeclareFontFamily{OMX}{yhex}{}
\DeclareFontShape{OMX}{yhex}{m}{n}{<-> yhcmex10 }{}

\newcommand*\diff{\mathop{}\!\mathrm{d}}
\renewcommand{\widering}[1]{\mathring{\wideparen{#1}}}

\begin{document}

\[\wideparen{abcggg}\quad \widetriangle{abc}\quad\widering{abc}\]
\[\bigintsss_0^5{x^3}\diff{x}\]

\end{document}
