Hi Muthu,

you could use the chngcntr package:

Code: Select all

\usepackage{chngcntr}
\counterwithout{equation}{chapter}

Hello Stefan,

Thanks for your suggestion..

When I tried to use the above code, it says that the chngcntr.sty is not found..

So, i have downloaded from ctan website and copied to my latex directory. But dosent recognize it.

It again says that the "File not found"

I have place the "style" file in
MikeTex -> tex -> latex -> chngcntr -> chngcntr.sty

Regards,
Muthu

Hi Muthu,

update the package database: click Start/MiKTeX/Options (or Settings) and click the button "Refresh FNDB". Afterwards MiKTeX should be able to find the downloaded package.

Hello stefan,

Thanks, it is working fine after refreshing FNDB..

Again, i have a doubt about equation numbers..

How can i restart the equation numbering from a particular section, by discontinuing the first.

It's like

(1)
(2)
(3)
.
.
.
again (1)
.
.

Please help me in this regard.

With regards,
Muthu

If that should be done each section use

Code: Select all

\counterwithin*{equation}{section})

If you want to do it once or just manually use \setcounter

Code: Select all

\setcounter{equation}{0}
