Interesting. The curve has a cute graph that makes this conjecture plausible, but not obvious. I'm curious: What led you to calculate this particular integral numerically? --Dan _____________________________________________________________________ "It don't mean a thing if it ain't got that certain je ne sais quoi." --Peter Schickele
