Actually, it is just about that bad! I saw the original post but didn't have time to reply then & forgot about it. My background is engineering, not math, and I'm fairly sure that the mathematical background would have been covered in an early grad level course on complex variables and analysis (whatever the exact name might have been, the course was required of all engineering grad students). I don't *think* that it came up formally before then, but I wasn't exactly the best student. Though, it's funny because I think the concept was used earlier, with natural logs anyway.

So, yeah, that's worth wibbling over! crazy
