WebIf you're in a nice scalar field (such as the reals or complexes) then you can always find a way to "normalize" (i.e. make the length 1) of any vector. The dot product is exactly what you said, it is the projection of one vector onto the other. You can draw a nice picture for yourself in R^2 - however sometimes things get more complicated. WebThe scalar projection of b onto a, also called the component of b along a, is the signed magnitude of proj ab (the signed length of the red vectors in Figure 3). It is positive if the angle between a and b is acute and negative if the angle is obtuse. The scalar projection of b onto a is denoted by comp ab. great clips oakley cincinnati https://acausc.com
