Unformatted text preview: ı + y −→ + z −→ k . We shall Fnd it convenient to move freely between the coordinate notation −→ v = ( x,y,z ) and the “arrow” notation −→ v = x −→ ı + y −→ + z −→ k ; generally, we adopt coordinate notation when −→ v is regarded as a position vector, and “arrow” notation when we want to picture it as an arrow in space. We began by thinking of a vector −→ v in R 3 as determined by its magnitude and its direction, and have ended up thinking of it as a triple of numbers....
