Question

what is dot product​

Answer 1

Answer:

It's sum of products of all vector elements.

Explanation:

Let's say you have 2 vectors: A = [a1, a2, ..., an] and B = [b1, b2, ..., bn]

Then dot product of these two vectors is equal:

A·B = a1 * b1 + a2 * b2 + ... + an * bn

Answer 2

Dot Product is the another term of Scalar Product which is product of the Euclidean magnitutes of two vectors and the cosine of the angle between them.
