Explanation:
Detailed explanation-1: -The formula for the angle between two vectors, a and b is =cos-1( a•b/|a||b|). Where vector a is (ax ay) and vector b is (bx by), the dot product a. b=ax b x+ a y by. The magnitude of the vector |a|=√(ax2+ay2) and the magnitude of the vector |b|=√(bx2+by2).
Detailed explanation-2: -Cosine of Angle Between Two Vectors So, the cosine of the angle between two vectors can be calculated by dividing the dot product of the vectors by-product of their magnitudes.
