While I was converting this with the inverse phasor transform, I wanna ask a question

P{ -4 cos(200t – 45°)}

Should I say -4-45 or 4-45 ?

I mean, do I have to preserve the negativity of the magnitude which is "4"?

As far as I have known that the magnitude is not a vectorial thing and then we are supposed to demonstrate it with always positive.
