Projection (linear algebra)

In linear algebra and functional analysis, a projection is a linear transformation from a vector space to itself (an endomorphism) such that . That is, whenever is applied twice to any vector, it gives the same result as if it were applied once (i.e. is idempotent). It leaves its image unchanged. This definition of "projection" formalizes and generalizes the idea of graphical projection. One can also consider the effect of a projection on a geometrical object by examining the effect of the projection on points in the object. (Wikipedia).

Proving that orthogonal projections are a form of minimization

Description: Orthogonal projections provide the closest point on a subspace to some point off the subspace. We use Pythagoras to prove that this is always the case. Learning Objective: 1) Given a subspace and a point, compute the closest point in the subspace to the given point. This
