I have two vectors
Vector A and B
Axi = -3
Ayj = 5.4
Bxi = 1.3
Byj = -3.9
I want the angle between them so I do the dot product
(-3)(1.3)+(5.4)(-3.9) = -24.96
Therefore the angle between them is
-24.96 = |-24.96|cos(theta)
Arccos(-24.96/24.96) = theta
Arccos(-1) = theta
Theta = pi = 180 degrees.
Is this correct?
