We showed earlier that ifv 2 W, then v= Xn k=1 (v;vk) kvkk2 vk SoP(v) =vfor allv 2 W. In particular, we get Lemma. P2=P. The mapPis called the orthogonal projection ontoW. WebThe notation for the orthogonal projection of v onto u (i.e. onto the line determined by u) is proju ( v ). Move v so that its tail lies on the tail of u. We know that proju ( v ) = a u for some scalar a. Since proju ( v ) - v is orthogonal to u , we have that (a u - v )• u = 0.
