You'll have to draw some sort of diagram because I'm getting confused which rotation you're referring to. The cos(theta) component would be for what direction the hall sensor is pointing to if the magnetic field is coming in a straight line at it from the magnet. The more complicated equation f(phi) would come into play if the magnet itself were not pointing at the hall sensor constantly, picrel.
