He is (deliberately) misrepresenting the discussion. The point was made
that the phasor was rotating clockwise, thus the angle decreasing, ie
becoming negative.

Untrue, no mention of the angle, as below ...

Equally, it is easy to mis-interpret the maths as Gareth has done in:

cos(wt) = 1/2 * ( e^(jwt) +e^(-jwt) )

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.

I see what you guys mean. He doesn't even understand what e^jwt is. He
sees it as no different from e^wt.
