When two vectors are operated under a dot product, the answer is only a number. A brief explanation of dot products is given below. Dot Product of Two Vectors. If we have two vectors, a = a x +a y and b = b x +b y, then the dot product or scalar product between them is defined as. a.b = a x b x ... In case a and b are parallel vectors, the resultant shall be zero as sin(0) = 0. Properties of Cross Product. Cross Product generates a vector quantity. The resultant is always perpendicular to both a and b. Cross Product of parallel vectors/collinear vectors is zero as sin(0) = 0. i × i = j × j = k × k = 0It contains several parallel branches for dot product and one extra branch for coherent detection. The optical field in each branch is symbolized with red curves. The push-pull configured ...

Please see the explanation. Compute the dot-product: baru*barv = 3(-1) + 15(5) = 72 The two vectors are not orthogonal; we know this, because orthogonal vectors have a dot-product that is equal to zero. Determine whether the two vectors are parallel by finding the angle between them.

The magnitude of the vector product →A × →B of the vectors →A and →B is defined to be product of the magnitude of the vectors →A and →B with the sine of the angle θ between the two vectors, The angle θ between the vectors is limited to the values 0 ≤ θ ≤ π ensuring that sin(θ) ≥ 0.

A typical example of this situation is when you evaluate the WORK done by a force → F during a displacement → s. For example, if you have: Work done by force → F: W = ∣∣ ∣→ F ∣∣ ...

order does not matter with the dot product. It does matter with the cross product. The number you are getting is a quantity that represents the multiplication of amount of vector a that is in the same direction as vector b, times vector b. It's sort of the extent to which the two vectors are working together in the same direction.For your specific question of why the dot product is 0 for perpendicular vectors, think of the dot product as the magnitude of one of the vectors times the magnitude of the part of the other vector that points in the same direction. So, the closer the two vectors' directions are, the bigger the dot product. When they are perpendicular, none of ...Properties of the cross product.
