ahh you've confused me cindy!

is it basically that you can't take the square root of a negative number?
u can

But in the world of Methods, the square root of a negative number doesn't exist.  :o

Yup, but in the world of Specialist it does :D

Where would maths be today without imaginary numbers! :P

You'd be amazed at how it pops up everywhere. Exposure to a lot of applied mathematics may even make you think that complex numbers are more practical than theoretical. They apply to all sorts of seemingly unrelated areas in pure and applied mathematics.

I love complex numbers - I perceive them as somewhat elegant for no apparent reason. I think they're the reason why I like AC circuits so much more than DC.

I like finding resonant frequencies with capacitors and inductors, even if they're not complicated or challenging. I just find them interesting...

How do you do that?

The resonant frequency occurs when the imaginary component of the impedence = 0, hence meaning that there's no phase difference between the EMF across the whole circuit and a resistor placed in the circuit.
