The angle between vectors A = i+ j and B = i- j

1.	The angle between vectors A = i+ j and B = i- j
Answer» Answer: 90 degrees Explanation: the vector i+j can be represented on argand PLANE by a point(1,1) and vector i-j by (1,-1). The angle between them is angle betweem their representations on argand plane. Hence the answer is 90 degrees or (-90) in terms of ANTICLOCKWISE notation from A to B.
