I thought it might be that, but it still makes no sense to me. Who or how
does changing the direction of rotation of a rotating vector change its
"size". Are you defining size as the rotation so that going from a + to
a - is like reversing the direction of a vector? I think most people
would consider the "size" of a vector to be the magnitude which is
independent of phase angle and so rotation, no?

Perhaps you can explain this with a little math?

Not my gibberish, refer to the original posting ...

The term e^(-jwt) isn't some magical time machine relating to "minus
time", e^(-jwt) is simply another way of writing 1/(e^jwt) which
is a value that decreases as t increasing.

Yeah, well this is not really correct unless I misunderstand what you
mean by "decreases". When the j factor is included in the exponent of
e, the function changes dramatically so that it does *not* exponentially
decrease in magnitude as t increases.
