Hi,
I know HOW to use a scalar product. However I don't know why do we need it and need a image of the result.

Hello, vinh48!
I know HOW to use a scalar product.
However I don't know why do we need it and need a image of the result.
As far as I know, the scalar product has no immediate meaning or image,
. . but it is used in a variety of formulas.
Given two vectors: .
. .
. .
. .
~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
I suggest that the scalar product is "similar" to a determinant.
A determinant has a value which, by itself, is meaningless.
However, it can be used in a variety of ways (e.g. Cramer's rule)
. . for a number of mathematical tasks.
