The Vector Dot Product
 
06:59
We learned how to add and subtract vectors, and we learned how to multiply vectors by scalars, but how can we multiply two vectors together? There are two ways to do this, and one of them is called the dot product. Let's learn how to find the dot product of two vectors now!

Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

How to find the scalar and vector Product of two vectors easily || how to find Dot and Cross product
 
05:53
In this video I have explained how to find scalar and vector product of two vectors , how to find scalar and vector product of two vectors when both the vectors are given in component forms . The dot (scalar) product is the trigonometric cosine rule applied to vectors. The result of a dot product is the cosine of the angle between the two vectors multiplied by the magnitudes of the vectors. The cross product is a vector at right angles to both of the given vectors and whose length is equal to the sine of the angle between the vectors multiplied by the magnitudes of the vectors. The length of the cross-product vector is also equal to the area of the parallelogram formed by these vectors. ............................................................................................................

Learn how to determine the dot product of vectors. The dot product of two vectors also called the scalar product of the vectors is the sum of the product of the components of the vectors in each direction. When the magnitudes of the vectors are known and the angle between the vectors is known, the dot product of the vectors is given by the product of the magnitude of the vectors and the cosine of the angle between the vectors. #trigonometry#vectors #vectors

Dot Product and Scalar Product of Vectors, Physics
 
10:35
The super easy and quick concept of Dot product of vectors or dot multiplication of vectors or scalar multiplication of vectors is explained in this video. The video covers all about the dot product and scalar produc of vectors. I will also tell you about: 1) Dot Product and Scalar Product of Vectors, Physics. 2) Physics - Mechanics: Vectors (12 of 21) Product Of Vectors: Dot Product 3) The Dot Product. 4) Class 12 Maths : Vectors - Dot product ( Scalar product ) Part 1. 5) Scalar Product or Dot Product (Hindi). 6) Cross Product and Dot Product: Visual explanation. 7) Dot vs. cross product | Physics | Khan Academy Dot product of vectors or scalar product of vectors is the multiplication of two or more vectors. Dot product or scalar product of two vectors always give us a number. a scalar function of two vectors, equal to the product of their magnitudes and the cosine of the angle between them. The Dot Product gives a number as an answer (a "scalar", not a vector). The Dot Product is written using a central dot: a · b This means the Dot Product of a and b We can calculate the Dot Product of two vectors this way: dot product magnitudes and angle a · b = |a| × |b| × cos(θ) Where: |a| is the magnitude (length) of vector a |b| is the magnitude (length) of vector b θ is the angle between a and b he dot product between two vectors is based on the projection of one vector onto another. Let's imagine we have two vectors aa and bb, and we want to calculate how much of aa is pointing in the same direction as the vector bb. We want a quantity that would be positive if the two vectors are pointing in similar directions, zero if they are perpendicular, and negative if the two vectors are pointing in nearly opposite directions. We will define the dot product between the vectors to capture these quantities. But first, notice that the question “how much of aa is pointing in the same direction as the vector bb” does not have anything to do with the magnitude (or length) of bb; it is based only on its direction. (Recall that a vector has a magnitude and a direction.) The answer to this question should not depend on the magnitude of bb, only its direction. To sidestep any confusion caused by the magnitude of bb, let's scale the vector so that it has length one. In other words, let's replace bb with the unit vector that points in the same direction as bb. We'll call this vector uu, which is defined by u=b∥b∥. u=b∥b∥. The dot product of aa with unit vector uu, denoted a⋅ua⋅u, is defined to be the projection of aa in the direction of uu, or the amount that aa is pointing in the same direction as unit vector uu. Let's assume for a moment that aa and uu are pointing in similar directions. Then, you can imagine a⋅ua⋅u as the length of the shadow of aa onto uu if their tails were together and the sun was shining from a direction perpendicular to uu. By forming a right triangle with aa and this shadow, you can use geometry to calculate that a⋅u=∥a∥cosθ,(1) (1)a⋅u=∥a∥cos⁡θ, where θθ is the angle between aa and uu.

Dot Product - Finding the Angle Between Two Vectors & Inverse Tangent - Physics
 
15:16
This Physics and Trigonometry video tutorial shows you how to find the angle between two vectors using the dot product in addition to another simple intuitive method using inverse tangent. This video may be useful for students taking precalculus. This video contains plenty of examples and practice problems.
Scalar Product and Vector Product Of two Vectors
 
03:43
Scalar Product The scalar product and the vector product are the two ways of multiplying vectors which see the most application in physics and astronomy. The scalar product of two vectors can be constructed by taking the component of one vector in the direction of the other and multiplying it times the magnitude of the other vector.

We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.
