Check the following minimal ...

If you don't want equation numbers, just don't use the \itemEq command defined in my previous post and write directly in math mode. Alternatively, if you have used \itemEq several times and you want to remove the number in a particular item, you can add \notag at the end (i.e. \itemEq{some math here ...

In page 11 of the AMS-LaTeX guide , it is suggested to insert the line

\numberwithin{figure}{chapter}

The following code solves the problem, I hope ...

The malayalam bundle is not part of TeX Live, so I cannot test it and help you to solve issues with your language. Sorry. It seems however that typesetting should be possible through the long route (latex+dvips+ps2pdf), since there are some examples with pstricks in the malayalam bundle ...

A quick fix: add manually some space, writing something like \iiint_0^{\hspace{6pt}\infty}. Anyway, are you sure you need this notation? For me, this is the first time I see something above the triple integral sign.

I think that the problem comes from the two lines pdflatex $1.tex that you'll see near the bottom in the script. Suppose that your source file is called foo.tex . First, it is compiled twice, so you get foo.dvi , with cross-references correctly settled. The successive commands dvips , psbook , psnup ...

I think that the technique you are using to change dimensions in the first page of chapters is error prone and not optimal. First, you do it manually, adding commands before and after each chapter heading. Second, it may be difficult to find a good point to place restoregeometry , since this command ...

Well, there are more free editors: TeXworks (already installed by the MacTeX distribution), TeXnicle, AlphaX, etc. In the Apple Store you may find TeXpad and Latexian.
