The problem is, if you it's a unit actor finding you that we and you doubt w Look at it a graph here. This is a squire. So if you is a unit, Wachter, we have magnitude of you. Is Nico to magnitude of APU is a good one And this magnitude have we If we could tow one over tough too and go between you and we is forty five degrees and the angle between you and W is ninety Reese. So we have you that b is equal to magnitude. You have You have managed to tick off the hams, Consign forty five degrees thiss is equal to one about one over which of two at one over. Return to this is equal to half You doubt it. W if they caught you magnitude of you Time's magnitude of w times call sign nineteen degrees. This's escort. You won that one. How's zero? Notice it equal to zero
