... Solution: The cross-product of the normal vectors is on the line of intersection. These normal vectors are u and v from the previous problem. So u × v = (−3, 1, 5) is a vector on the line of intersection. To check this answer, note that (−3, 1, 5) satisfies both plane equations. ...

... The formal definition of two vectors being parallel (Definition 2.13) is that their direction vectors are equal or differ by a factor of – 1. However, the most convenient way to test whether two given vectors are actually parallel is to use the following criterion. Its equivalence to the definition ...

... As we have seen in the introduction, a vector space is a set V with two operations: addition of vectors and scalar multiplication. These operations satisfy certain properties, which we are about to discuss in more detail. The scalars are taken from a field F, where for the remainder of these notes F ...

3.7.5 Multiplying Vectors and Matrices
... It is important to realize that you can use \dot" for both left- and rightmultiplication of vectors by matrices. Mathematica makes no distinction between \row" and \column" vectors. Dot carries out whatever operation is possible. (In formal terms, a.b contracts the last index of the tensor a with th ...

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.
