If we have two vectors A and B with an angle #theta# between them when they are joined tail to tail ( To remove ambiguity, #theta < pi#), then the projection of either vector (say, B) in the direction of A is the component of B along A and is given by, B #Cos theta#.
Similarly, projection of A in the direction of B is A #Cos theta# .
