(Pure Mathematics) Sorry Engineer coming out[:D] <br />[/quote] <br /> <br />But isn't it that by definition anything divided by itself is 1?

But it has been a few years since leaving University. I remember something about using this in design a forth order Chebychev Filter (Excuse the spelling!) <br /> <br />[/quote]Actually, that's the tricky thing. In some fields of higher matheimatics the definition that any number divided by itself equals one is "superior" to the rule that any number divided by zero is undefined. So the correct answer to zero divided by zero equals one. That's one definition used in some higher mathematical fields. But usually it's just considered indeterminate. <br /> <br />So there is no real answer - it depends on what you're doing. <br /> <br />Kinda twists your brain around, doesn't it? <br /> <br />I think I learned this in abstract algebra, or perhaps it was in Partial Differential Equations. <br /> <br />[/quote] <br /> <br />Don't go to school for thirty years and they go and change EVERYTHING. <br /> <br />I remember specifically being told that 0/0 was NOT 1 but that was a long time ago. I thought (i) was going to come up in this, I never did get that square root of -1 stuff. That's probably why I became a mechanic.
