WebbWhat I want to show you in this video, and you could view it either as a change of basis or as a linear transformation, is that when you multiply this orthogonal matrix times some vector, it preserves-- let me write this down-- lengths and angles. So let's have a little touchy-feely discussion of what that means.

Therefore by Theorem 5.2.1, we can find a matrix A such that T(→x) = A→x. The columns of the matrix for T are defined above as T(→ei). It follows that T(→ei) = proj→u(→ei) gives the ith column of the desired matrix. lewiston ny planning boardWebbThen T is a linear transformation, to be called the zero trans-formation. 2.
