Lecture 14: Orthogonal vectors and subspaces

the 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.

This can be proved by repeated application of the Pythagorean Theorem. Example The distance between P 1 = (2;3;1) and P 2 = (8; 5;0) is d(P 1;P 2) = p (8 2)2 + ( 5 3)2 + (0 1)2 = 36 + 64 + 1 = p 101 ˇ10:05: 2 Equations of Surfaces In two dimensions, the solution set of a single equation involving the coordinates x and/or y is a curve.
