Here are a couple of mathematical formulas to copy from:

How do we calculate such a limit?  Answer: we replace 
$(r(t_i) - r(t_{i - 1}))$ by $r'(t_i^o)(t_i - t_{i - 1})$, where
$t_i^o\in [t_{i - 1} - t_i]$.  So (*) becomes
$$
\sum_{i = 1}^N f(r(t^*_i))\cdot r'(t_i^o)(t_i - t_{i - 1})
$$
The limis of this is readily calculable; it is
$$
\int_\rho^\sigma f(r(t))\cdot r'(t)dt = \int_a^b f(z)dz
$$

Now we'll show the ``code'' needed to change margins.  You will
readily discern that the text below has a different left margin than
the one prevailing in this document up to now.

{\indentpar{.3in}
Four score and seven years ago our fathers brought forth on this continent
a new nation, conceived in liberty, and dedicated to the proposition
that all men are created equal.\par}

{\indentpar{.7in}
Now we are engaged in a great civil war, testing whether that nation,
or any nation so conceived and so dedicated, can long endure.  We are
met on a great battlefield of that war.  We have come to dedicate a
portion of that field as a final resting-place for those who here gave
their lives that the nation might live.\par}

You will notice when looking at the \TeX-code that each paragraph in
the indented material must be treated separately.

Let's now put in some diacritical marks: ca\~non, \'el\`eve,
K\"oln.  Now some Greek letters: $\pi$, $\alpha$, $\beta$,
$\gamma$, $\Sigma$, and $\Omega$.

And we finish up with a {\bf Table}!

\settabs 5 \columns
\+ 1 & 2 & (prime) & (square) & 5 \cr
\+ 6 & (prime) & 8 & (square) & 10 \cr
\+ (prime) & 12 & (prime) & 14 & 15 \cr
