>hmmm. My math is getting rusty... in the expression e^(i*pi), what does i mean ?
The imaginary unit; i^2 = -1. Here we are talking about complex numbers. See my calculation in my reply to Tracy.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
