Thanks Antonio for sharing your integral, but the symbols
don't come up. I get the following messages from Acrobat
reader.

Unable to extract the embedded font 'ELVJST+symbol'.
Unable to find or create the font 'JXVQPY+Times-Bold'.

I have no idea what this stuff means. Is their some other
reader I should use.
