Lecture 14: Orthogonal vectors and subspaces
ocw.mit.eduthe Pythagorean theorem to prove that the dot product xTy = yT x is zero exactly when x and y are orthogonal. (The length squared ||x||2 equals xTx.) Note that all vectors are orthogonal to the zero vector. Orthogonal subspaces Subspace S is orthogonal to subspace T means: every vector in S is orthogonal to every vector in T.
