Negative Dot Product
medium
The dot product can be negative. What does a negative dot product between two vectors imply?
A
The vectors are orthogonal — a negative dot product is equivalent to a zero dot product in magnitude
B
The vectors point in generally opposite directions — the angle between them is greater than 90°
C
The vectors are linearly dependent — one is a negative scalar multiple of the other
D
The vectors have different norms — one is much longer than the other causing directional mismatch
