→Just a thought: "it works ..." ''at what''? Using "i" as an exponent may have value to the extent that any orthogonal coordinates have value, but it could be "j" or "k" to accomplish the same goal.
The square root of -1 was introduced as first as a party trick - to solve cubic equations in contests. As so often in mathematics, it suddenly became quite relevant, and nowadays, complex analysis is something every undergraduate in maths or physics has to know! It doesn't matter how you feel about it, it is only important that it works... --[[User:AugustO|AugustO]] ([[User talk:AugustO|talk]]) 18:43, 17 August 2015 (EDT)
