  • What does the dot product of two vectors represent?
    The dot product tells you what amount of one vector goes in the direction of another For instance, if you pulled a box 10 meters at an inclined angle, there is a horizontal component and a vertical component to your force vector So the dot product in this case would give you the amount of force going in the direction of the displacement, or in the direction that the box moved This is
  • What is the dot product and why do we need it?
    I understand how to calculate the dot product of the vectors But I don't actually understand what a dot product is, and why it's needed Could you answer these questions?
  • What is the use of the Dot Product of two vectors?
    19 Re: " [the dot product] seems almost useless to me compared with the cross product of two vectors " Please see the Wikipedia entry for Dot Product to learn more about the significance of the dot-product, and for graphic displays which help visualize what the dot product signifies (particularly the geometric interpretation)
  • Proof of dot product formula. - Mathematics Stack Exchange
    The dot product essentially "multiplies" 2 vectors If the 2 vectors are perfectly aligned, then it makes sense that multiplying them would mean just multiplying their magnitudes
  • What is the dot product of complex vectors?
    This complex "dot product" is sometimes called a Hermitian form This specific separate term serves as a way to make it clear that it might not comply with the usual definition of a dot product, if you don't generalize that definition as shown above
  • linear algebra - difference between dot product and inner product . . .
    I was wondering if a dot product is technically a term used when discussing the product of $2$ vectors is equal to $0$ And would anyone agree that an inner product is a term used when discussing
  • What is the general formula for calculating dot and cross products in . . .
    $ \theta $ and $ \phi $ angles are as represented in the image below: What is the general formula for taking dot and cross products of these vectors? $ \overrightarrow {V_1} \bullet \overrightarrow {V_2} = ? \\ \overrightarrow {V_1} \times \overrightarrow {V_2} = ? $ If you need an example, please work on this one:
  • linear algebra - Dot product vs Matrix multiplication, is the later a . . .
    Dot product has a specific meaning Matrix multiplication has no specific meaning, than may be a mathematical way to solve system of linear equations Why, historically, do we multiply matrices as we do? Coming back to dot product - Algebraically, the dot product is the sum of the products of the corresponding entries of the two sequences of
  • linear algebra - Which item do we transpose for the dot product . . .
    The goal of the dot product (also known as the scalar product) is to provided a way to multiply two vectors together to yield a scalar value So, my inital question of which one should be transposed depends, as long as they are both one-dimensional vectors that have the same dimension and whichever item is being transposed will lead to a scalar
  • What does the dot product of a tensor and a vector represent?
    The meaning of the dot product of two vectors has been well explained below: What does the dot product of two vectors represent? What is physical interpretation of dot product? [duplicate] But, what is the meaning of the dot product of a tensor and a vector, if there is any?
