... 1 (called roots of unity). The best way to understand how to do this is to realize that if we let θ run from, say, 0 to 2π then the complex numbers eiθ trace out the unit circle. Finding the nth roots of unity amounts to cutting the unit circle into n equal arcs and finding the complex numbers corr ...

... there exists an orthogonal matrix Q and a diagonal matrix D so that QT AQ = D. That is, A is orthogonally similar to a diagonal matrix. In essence, this says that the way A acts on Rn is to stretch it in n orthogonal directions. One can find Q as follows: (a) find the eigenvalues of A; (b) for each ...

Basis (linear algebra)
Basis vector redirects here. For basis vector in the context of crystals, see crystal structure. For a more general concept in physics, see frame of reference.A set of vectors in a vector space V is called a basis, or a set of basis vectors, if the vectors are linearly independent and every vector in the vector space is a linear combination of this set. In more general terms, a basis is a linearly independent spanning set.Given a basis of a vector space V, every element of V can be expressed uniquely as a linear combination of basis vectors, whose coefficients are referred to as vector coordinates or components. A vector space can have several distinct sets of basis vectors; however each such set has the same number of elements, with this number being the dimension of the vector space.
