Dot Product A vector has magnitude (how long it is) and direction. Here are two vectors They can be multiplied using the Dot Product (also see Cross Product).. Calculating. 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 Although this formula is nice for understanding the properties of the dot product a formula for the dot product in terms of vector components would make it easier to calculate the dot product between two given vectors. In modern geometry Euclidean vectores are often defined by using vector vectores. In this case the dot product is used for defining vectorgths (the vectorgth of a vector is the square root of the dot product of the vector by itself) and angles (the cosine of the angle of two vectors is the quotient of their dot product by the product of their vectorgths).

Multiply by a constant Make an existing vector stronger (in the same direction). Dot product Apply the directional growth of one vector to another. The result is how much stronger weve made the original vector (positive negative or zero). Today well build our intuition for how the dot product works. This relation is commutative for real vectors such that dot(uv) equals dot(vu). If the dot product is equal to zero then u and v are perpendicular. For complex vectors the dot product involves a complex conjugate. This ensures that the inner product of any vector with itself is real and positive definite. When two vectors are multiplied with each other and answer is a scalar quanvectory then such a product is called the scalar product or dot product of vectors. A dot (.) is placed between vectors which are multiplied with each other thats why it is also called dot product. Scalar vector .vector. Vector dot product examples
