Take the equation e^(pi)i = -1, which has applications in differential equations which is used all over the place. | ||

The interesting thing no one has mentioned is that j (i, whatever) _isn't a number_! It's actually a constant (ie a name for a specific value). Saying it is a number is equivalent to me saying that MAX_INT is a number...because, after all, MAX_INT = 2^31 - 1... | ||

That's the complex analysis treatment anyway, not sure about engineering. | ||

Where are you even getting this from? I just checked my textbook and none of what you're saying is in there. | ||

THINK about it...you're a person...named (presumably) Jalstar. Jalstar is not a person...it's a NAME. The physical body everyone knows as Jalstar is a person....yet 'Jalstar' isn't. It's not that hard a concept. Drop the diff eq book and read about the difference between a pointer and an object...a variable and a value...a constant and the value it represents. | ||
