WebProjections. One important use of dot products is in projections. The scalar projection of b onto a is the length of the segment AB shown in the figure below. The vector projection of b onto a is the vector with this length that begins at the point A points in the same direction (or opposite direction if the scalar projection is negative) as a.

WebGiven A x⃑ = b⃑ where A = [[1 0 0] [0 1 0] [0 0 1]] (the ℝ³ identity matrix) and x⃑ = [a b c], then you can picture the identity matrix as the basis vectors î, ĵ, and k̂.When you multiply out the matrix, you get b⃑ = aî+bĵ+ck̂.So [a b c] can be thought of as just a scalar multiple of î plus a scalar multiple of ĵ plus a scalar multiple of k̂.
