So.. Errr, yeah. -confused-
-Note- AP Physics problems. FUN TIMES AHEAD!
52) Two vectors A and B have precisely equal magnitudes. In order for the magnitude of A+B to be larger than the magnitude of A-B by the factor n, what must be the angle between them?
He had given us a few hints, but I can't seem the piece together how I'd actually use these hints in practice.
Hint 1: Law of Cosines
Hint 2: Trig Identities
So if anyone could explain this problem, that would be dandy.
