		The fundamental concept in linear algebra is that of a vector space or linear space.
		Given a vector space V, any nonempty subset W of V which is closed under addition and scalar multiplication is called a subspace of V. It is easy to see that subspaces of V are vector spaces (over the same field) in their own right.
		Given two vector spaces V and W over the same field F, one can define linear transformations or “linear maps” from V to W. These are maps from V to W which are compatible with the relevant structure—i.e., they preserve sums and scalar products.

		A vector space (or linear space) is the basic object of study in the branch of
		vectors, and the operations one can perform upon these vectors such as addition of vectors, scalar multiplication, with some natural constraints such as closure of these operations, associativity of these and combinations of these operations, and so on, we arrive at a description of a mathematical structure which we call a vector space.
		To determine if a set V is a vector space, one only has to specify the set V, a field F, and define vector addition and scalar multiplication in V.

	PlanetMath: dimension (vector space)
		Note: in circumstances where the choice of field is ambiguous, the dimension of a vector space depends on the choice of field.
		For example, every complex vector space is also a real vector space, and therefore has a real dimension, double its complex dimension.
		This is version 5 of dimension (vector space), born on 2002-06-01, modified 2004-03-04.

	Normed vector space (Site not responding. Last check: 2007-10-21)
		If V is a vector space over a field K (which must be either the real numbers or the complex numbers), a norm on V is a function from V to R, the real numbers — that is, it associates to each vector v in V a real number, which is usually denoted
		Examples of infinite dimensional normed vector spaces can be found in the Banach space article.
		A surjective isometry between the normed vector spaces V and W is called a isometric isomorphism, and V and W are called isometrically isomorphic.

	Real Vector Spaces
		Since a vector space has a constant number of vectors in a basis, that number n is characteristic for that space and is called the dimension of that space.
		The space generated by D is called the row space of A. The rows of A are a generating set of the row space.
		A is the supplementary vector space of B with respect to V. B is the supplementary vector space of A with respect to V. A and B are supplementary vector spaces with respect to V. Basis and direct sum

		A particle moving in three-dimensional space can be located at each instant of time t by a position vector r drawn from some fixed reference point O. Since the position of the terminal point of r depends on time, r is a vector function of t.

	Topological Vector Space
		A normed vector space is a topological vector space, deriving its topology from the metric.
		In a metric space, the translate of an open ball is an open ball, since the distance between two points does not change; but in a topological group, we have to use the properties of continuity to prove translation preserves open sets.
		In the above example the kernel is the y axis, and the quotient space is the x axis, which is indeed a topological vector space.

		The sensor should truly make vector measurements as the angular response should be equal to B cos f where f is the angle between the field vector and the sensor axis.
		One sensor was parallel to the spacecraft spin axis one was normal to the spin and the third was at a point 2/3 of the length of the 5m boom and tilted at a 45o angle in the radial direction.
		At low frequencies in quiet fields, calculation of the vector field from the sine wave amplitude and phase and the steady component parallel to the spin axis could be provided by either the inboard tilted sensor on the two outboard sensors.

		But, as the example shows, the placement of an element is relative to ancestors and siblings, so these elements' padding and margin properties have an effect on their children.
		For example, by setting the 'float' property of an image to 'left', the image is moved to the left until the margin, padding or border of another block-level element is reached.
		Examples of constraints of the presentation medium are: limited resources (fonts, color) and limited resolution (so margins may not be accurate).

	Mathies are a Vector Space
		Now multiplying a vector, say our good friend M, by a constant, say 1/3, we come to the obvious conclusion that (1/3)M = R. Moving onto the body of the proof we now have to prove the 9 (in this case) axioms of a vector* space.
		Axiom 3: u+v is an element of the vector space of mathies.
		And the vector space in question isn't using that particular basis.

	Vector Space
		An abstract real vector space is an additive commutative group with one additional operation: its elements may be multiplied by real numbers (scalars).
		It's by no means a group operation (except for the case when we look at the set R of real numbers as a real vector space) because in a group operations both operands must come from the same set.
		Thus, vectors and Vector Spaces are born simultaneously.

		The state space model for an nth-order system is a set of n 1st-order differential equations, called the state equations, and a set of p algebraic equations, called the output equations.
		As an example of how the initial conditions cause different outputs for the two models, each model was given an initial state vector consisting of 1 for each element (4 of them for the full-order model, 3 for the reduced-order model).
		Obviously, the mode that is missing from the poles of the transfer function is the one which was cancelled by a zero in the original form of the transfer function.

	Vector Area 3 (Site not responding. Last check: 2007-10-21)
		If the three triangles formed by the origin and the three vectors are not restricted to a plane, then the area still adds up, but now instead of a signed quantity, you must consider the area as a vector quantity.
		The length of the vector is the magnitude of the area, and the direction of the vector is normal to the plane of the triangle, pointing in a direction determined by the right-hand-rule and the order in which the two vectors are named.
		However, to make the equation work, the area of each triangle needs to be treated as a vector as well, whose length is equal to the magnitude of the area, and whose direction is normal to the plane of the triangle.
