Determining the projection of a vector on s line. The vector projection of a vector a on (or onto) a nonzero vector b (also known as the vector component or vector resolution of a in the in geometric algebra, . In functional analysis and linear algebra, the projection is defined as a linear transformation from some vector space onto itself in such a way that if the transformation is applied two times to some value, then it will provide the same value.

Linear algebra – linear algebra is the branch of mathematics concerning vector spaces and linear mappings between such spaces it includes the study of lines, planes, and subspaces, the set of points with coordinates that satisfy a linear equation forms a hyperplane in an n-dimensional space.

Projection (linear algebra) 2 classification for simplicity, the underlying vector spaces are assumed to be finite dimensional in this section the transformation t is the projection along k. I ended up working out the solution for the projection onto the kernel for myself and it was a great exercise in trying to connect the usual notion of linear algebra with the graphical formulation i really like the two-colour notation for the bizarro and the derivation of the usual textbook formula for the projection onto the image.
