For example hx+1,x2 +xi = R1 −1 (x+1)(x2 +x)dx = R1 −1 x3 +2x2 +xdx = 4/3. The reader should check that this gives an inner product space. The results about projections, orthogonality and the Gram-Schmidt Pro-cess carry over to inner product spaces. The magnitude of a vector v is defined as p hv,vi. Problem 6.

Example: rotation by θ in R2 is given by ... • usually computed using a variation on Gram-Schmidt procedure which is less sensitive to numerical (rounding) errors • columns of Q are orthonormal basis for R(A) Orthonormal sets of vectors and QR factorization 4–15.Example Euclidean space Consider the following set of vectors in R2 (with the conventional inner product ) Now, perform Gram–Schmidt, to obtain an orthogonal set of vectors: We check that the vectors u1 and u2 are indeed orthogonal: noting that if the dot product of two vectors is 0 then they are orthogonal.

The term is called the linear projection of on the orthonormal set , while the term is called the residual of the linear projection.. Normalization. Another perhaps obvious fact that we are going to repeatedly use in the Gram-Schmidt process is that, if we take any non-zero vector and we divide it by its norm, then the result of the division is a new vector that has unit norm.Courses on Khan Academy are always 100% free.

The Gram-Schmidt theorem states that given any set of linearly independent vectors from a vector space, it is always possible to generate an orthogonal set with the same number of vectors as the original set. The way to generate this set is by constructing it from the original set of vectors by using Gram-Schmidt's orthogonalization process:
