... conditions, but when the correct minimal polynomial has very large coefficients there can be errors. Example 1. In PARI, set f(x) = x^3 + 453603*x^2 + 51438694443*x - 51247953119 and then type v = polroots(f(x)). The answer is a vector of length three whose first coordinate is 0.99628311790670273466 ...

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.
