Hi, I'm learning vectors and there's two notions which I don't distinguish :

Is the orientation of a vector (determined by the angle it has) the same thing as the direction of a vector ???

thank you

Yes. The direction of the vector is quantified by the angle it makes with some reference axis.

Vector question

Well, how else would you define the direction of a vector?
