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 xaxis.
