I've been going along in this physics book and I've been getting along in it. Vectors took me some time though, and i sitll have questions. So i understand how a vector "displacement" and be gained from a bunch of distances travelled, and i know the <x,y> components would simply be total east and total north traveled. But then Velocity vectors throw me off. If you're going say 30 degree North of East, then does that mean you're going X amount in the east direction and y amount in the north direction? Also, when you're in a boat crossing a river and you're going east to west at a speed, and the river is going north to south at some speed, can you pretened those are actually <x,y> component of the resultant, which will be the actual direction and speed you travel due to the effects of both the river and your own speed?
