You are definitely right, you're a programmer. A mathematician would have said i=sqrt(-1). :smile:
(And an EE major would say I=V/R.)
You are right about that 'i' is the square root of -1. I never used 'i' as an increment in my programming classes in college. Couldn't bring myself to do it.
I don't really use 'i' as an engineer. But know that I could use it.
