Parallel vectors dot product.

As the dot product is the product of the magnitudes of the vectors multiplied by the cosine of the angle between them, it is zero when the cosine of the angle between both vectors is zero. This happens when the angle between them is 9 0 ∘ or − 9 0 ∘ (or 2 7 0 ∘ ), that is, when they are perpendicular.The dot product of two vectors tells us what amount of one vector goes in the direction of another. The dot product of two vectors 𝐀 and 𝐁 is defined as the magnitude of vector 𝐀 times the magnitude of vector 𝐁 times the cos of 𝜃, where 𝜃 is the angle formed between vector 𝐀 and vector 𝐁. In the case of these two ...May 5, 2023 · As the angles between the two vectors are zero. So, sin θ sin θ becomes zero and the entire cross-product becomes a zero vector.

This contrasts with the dot product, which is maximum for parallel vectors and zero for perpendicular vectors. Notice that the cross product does not commute, i.e. the order of the vectors is important.The dot product of two unit vectors behaves just oppositely: it is zero when the unit vectors are perpendicular and 1 if the unit vectors are parallel. Unit vectors enable two convenient identities: the dot product of two unit vectors yields the cosine (which may be positive or negative) of the angle between the two unit vectors.The dot product is zero when the vectors are orthogonal, as in the angle is equal to 90 degrees.
