Some properties of vectors - there is a point I don't understand it .

Hi



Two vectors A and B are equal if they have the same magnitude and the same direction . this property allows us to translate a vector parallel to itself in a diagram without affecting the vector . In fact , for most purposes, any vector can be moved parallel to itself without being affected .



can you give me an example of that point

Let u = i + j

Let v be the vector that extends from (2, 1) to (3, 2)

Then |u| = |v| = sqrt(2)
and both vectors make an angle of 45 degrees with the positive x-axis.

Thanks a lot
