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.
