Another example: Let $(x_n)=\sin(\frac{n\pi}{2})$. Obviously $(x_n)$ is a non-convergent sequence, buy if you consider the subsecuence: $(x_n)_{n=2k}$, with $k\in \mathbb{N}$, then $(x_n)_{n=2k}\to 0$.

Is it possible to have a convergent subsequence of a divergent sequence?
I have a form as a PDF file.  I would like to use LaTeX/TeX to overlay my text over the form, and send the output to either a print or another PDF file.

Is this possible?  How would I go about it?
