Scalar products (also known as dot or inner products) are the simplest form of multiplication between two vectors. There are two complementary definitions for the scalar product of two vectors and .
The first is in terms of the vector components and , where :
The second uses the magnitudes of and angle between and :
How is the projection of onto related to the scalar product of and ?
How about for the projection of onto ?
