Created by Sal Khan. Sort by: Web1 the projection of a vector already on the line through a is just that vector. In general, projection matrices have the properties: PT = P and P2 = P. Why project? As we know, the equation Ax = b may have no solution. The vector Ax is always in the column space of A, and b is unlikely to be in the column space. So, we project b onto a vector p in the column … WebSep 17, 2024 · To compute the orthogonal projection onto a general subspace, usually it is best to rewrite the subspace as the column space of a matrix, as in Note 2.6.3 in Section 2.6. Theorem 6.3.2. Let A be an m × n matrix, let W = Col(A), and let x be a vector in Rm. Then the matrix equation. fact family blank worksheet
