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.

See, he has trimmed his part, which clearly didn't refer to the true
usage of negative frequency. I simply over estimated is ability to grasp
the meaning of what I'd said without more detail. This was obvious as he
also claimed claimed that division was impossible with complex numbers.

He will attempt to drag this out, as he always does, but a look in the
archive will show his claims to be nonsense. He drags this up from time
to time, generally after a drubbing, He really doesn't like being proven
wrong. Look at the date, he has been dragging this up with boring
regularity since then. I've lost count of the times it has been
explained to him. He has finally got the idea of the clockwise rotating
phasor. He struggled with the idea that, as the phasor rotated, the
angle became more negative, and thus decreased. eg -20 -10

Well, brian, once again you resort to personal abuse which is not
recommended
for giving the impression that you are a competent engineering grownup
engaging
in an international debate.

You are correct in that you point out that I trimmed the post, and I did so
to limit
it to answer the question that was posed by Rickman

There was nothing in Rickman's query about negative frequency so I do not
see what it is that you are setting out to achieve by introducing that
non-sequitur
of a red herring?

You been shot down again.

You are hurling abuse, as you always do.

Only you thinks otherwise.

Everyone else is laughing at you.

Well, brian, once again I re-iterate that it is only you who
is hurling abuse, just as you do above.

Shame on you.

Why do you behave like that when it is you who has repeatedly-ad-nauseam
raised the spectre of DSP mathematics over the past week; why resort to
rather
silly and infantile abuse; why not discuss the technical matter that you
have
raised over and over again?

Why resort to abuse when you have been challenged, for despite what you
say, I do not?

Brian, is there some truth in G7FUJ, Cum's assertion that you were
dismissed without references from your job as a mathematics teacher,
for your confusion about a change in direction of a phasor as you
express above would be very worrying?

When you say "more", in "more negative" above, you are saying
that the magnitude of the angle is increasing

There seems to be a fundamental problem in your grasp of the direction
of vectors, because there is nothing beween clockwise and anti-clockwise,
left and right, up and down, or, in this case, negative and positive, for
they
are merely words used to disnmbiguate the direction of the vector.

Brian, why don't you just give up whilst you are still behind?
