	math lessons - Linearity of differentiation
		In mathematics, the linearity of differentiation is a most fundamental property of the derivative, in differential calculus.
		It follows from the sum rule in differentiation and the constant factor rule in differentiation.
		Thus we can say that the act of differentiation is linear, or the differential operator is a linear operator.

	Sum rule in differentiation - Wikipedia, the free encyclopedia
		The sum rule in differentiation is possibly the most useful rule in differentiation.
		The rule itself is a direct consequence of differentiation from first principles.
		The sum rule in differentiation can be used as part of the derivation for both the sum rule in integration and linearity of differentiation.

	Linearity
		As defined elsewhere, we describe a linear space as a vector space if its addition is complete: as it has already been constrained to be associative and cancellable, this makes it a group (unless you object to the empty group).
		It follows from the definitions that any linear map respects differences, in the sense that it induces a map from the differences of its domain to those of its range: the equivalence relation defining differences is stated purely in terms of addition, which a linear map respects, so the linear map respects the equivalence relation.
		For any linear space, L, we define the span of a function (:f:L) to be the minimal linear subspace of L of which (f) is a subset.

	AMERICAN MATHEMATICAL MONTHLY -June/July 2001
		This is a short informal history of differential forms from the time when they barely existed to the time of de Rham's paper (1931) when the "modern" phase began.
		The story then starts with the question "which one-forms are differentials of functions?", touches on Pfaff's problem, goes through the development of the theory of "complete integrability" of systems of one-forms (Theorem of Frobenius), and moves on to the Poincaré Lemma, the basis for the modern uses of differential forms.
		The concept of a linear transformation on vector space and, more generally, the concept of a module homomorphism, are basic in mathematics.

	I. Linearity
		The leitmotifs are the notions of linearity and orthogonality.
		A linear transformation is a function on vectors, with the property that it doesn't matter whether linear combinations are made before or after the transformation.
		A linear transformation is a function defined on vectors, and the output is always a vector, but the output need not be the same kind of vector as the input.

	Linearity
		In words, this means that a linear system produces the same output for two added signals, or for a signal multiplied by a constant, whether those operations are carried out before or after the signals pass through the system.
		If a system is linear, it is amenable to analysis by linear algebra, which is a vast mathematical structure of immense power.
		The mathematical method employed by the authors was “principal component analysis”, which is a form of linear algebra applied to statistical data.

		Under Linearity, it seems like there is a typo in the formula, bg(x) becomes bf'(x) which doesn't seem right but its been a long time since I studied this sort of thing so I could be wrong.

		In section 2.2, we will systematically write all linear transformations from F^n to F^m as multiplying an n-vector by an m x n matrix, to get an m-vector.
		Since T is linear, v1 and v2 in N(T) implies T(av1 + bv2) = T(av1)+T(bv2) = aT(v1) + bT(v2) = a0_V + b0_V = 0_V, so N(T) is closed under + and *, and so a subspace.
