Before you can call TeX from Scribus you have to install TeX first.
Fortunately TeX is easy to install.  Assuming you use MSWin of some
variety just Google on Miktex, go to that site, and follow the
instructions.

As previously stated TeX is optimized for tasks like inserting a math
(greek) character or a simple formula in the middle of a sentence.
more complex formulae are inserted between paragraphs. You just use
single dollar signs to enclose the math notation. Here are examples:
Here is a simple formula $e=(mc)^2$ inserted in a sentence.
Typing Greek letters is as easy as $\pi$, e.g.:
\alpha \beta \gamma (or capitalized as \Gamma) and so  on.

To display a more complex formula between paragraphs just use double
dollar signs. For example to show the square root of the log of x
between paragraphs the tex user types:
$$\sqrt{\,\log x}$$
This notation is not intuitive but it works.
The inventor of TeX is Professor Donald Knuth, a well-known
mathematician. Perhaps you have heard of his work, "Seminumerical
Algorithms"

There is a tool optimized for your kind of work. Its name is TeX. You
can use bits and pieces of it in Scribus 1.3.5 but for the full power
of the product you should use it directly.  I suspect all the
examples listed above will work in Scribus 1.3.5.

Installation of TeX is fairly easy. Google under Miktex and follow
the instructions at that site. If you don't use MSWin then Google
under texlive.

There are several mailing lists and at least one newsgroup chock full
of TeX experts who will help you along. There are excellent books
