WebThe dot product as projection. The dot product of the vectors a (in blue) and b (in green), when divided by the magnitude of b, is the projection of a onto b. This projection is illustrated by the red line segment from the tail of b to the projection of the head of a on b. You can change the vectors a and b by dragging the points at their ends ... WebJun 15, 2024 · The scalar projection is a scalar, equal to the length of the orthogonal projection of a on b, with a negative sign if the projection has an opposite direction with respect to b . Multiplying the scalar projection of a on b by b ^ converts it into the above-mentioned orthogonal projection, also called vector projection of a on b .
