Let consider value for vector A as (2 , 3) and B as (4 , 6 The dot product $$\langle x,y \rangle$$ is known by different names, and it is also called, inner product or scalar product. Essentially, the dot product is matrix product if we consider $$x \in \mathbb{R}^n$$ and $$y \in \mathbb{R}^n$$, then the dot product is defined as: $\langle x, y \rangle = \sum_{i=1}^n x_i y_i = x^t \cdot y$ Some.

### Online calculator: Dot product

So let's say that we take the dot product of the vector 2, 5 and we're going to dot that with the vector 7, 1. Well, this is just going to be equal to 2 times 7 plus 5 times 1 or 14 plus 6. No, sorry. 14 plus 5, which is equal to 19. So the dot product of this vector and this vector is 19 The difference in between cross product & dot product is that the cross product produces another vector while dot product produces a scalar value.

Geometrically, the dot product of two vectors is the magnitude of one times the projection of the second onto the first Proof: The cross product creates a vector that is perpendicular to both the vectors cross product multiplied together. However, the zero vector has no length or direction. Hence, there is no vector that is perpendicular to both some vector $\vec{u}$ and the zero vector $\vec{0}$.For convention, we say the result is the zero vector, as it can be assigned any direction because it has no magnitude Vector Product of Vectors. The vector product and the scalar product are the two ways of multiplying vectors which see the most application in physics and astronomy.
