	LOGARITHM - LoveToKnow Article on LOGARITHM
		Logarithms were originally invented for the sake of abbreviating arithmetical calculations, as by their means the operations of multiplication and division may be replaced by those of addition and subtraction, and the operation.s of raising to powers and extraction of root~s by those of multiplication and division.
		The logarithms are strictly Napierian, and the arrangement is identical with that in the canon of 1614.
		Logarithms of the ratios of arcs to tangents from 0q.00000 to 0~o5ooo, and log tangents throughout the quadrant.

	Natural logarithm
		The natural logarithm is the logarithm to the base e, where e is approximately equal to 2.71828...
		Second, expressions in which the unknown variable appears as the exponent of e occur much more often than exponents of 10 (because of the "natural" properties of the exponential function which allow it to describe growth and decay behaviors), and so the natural logarithm is more useful in practice.
		The derivative of the natural logarithm is given by

	Integration by parts - Wikipedia, the free encyclopedia
		In calculus, and more generally in mathematical analysis, integration by parts is a rule that transforms the integral of products of functions into other, possibly simpler, integrals.
		Note that the original integral contains the derivative of g; in order to be able to apply the rule, the antiderivative g must be found, and then the resulting integral ∫g f′ dx must be evaluated.

		Applying a negative DS-Max logarithm assigns the more information to the less probability and, because the DS Max logarithm of a product is the sum of the DSMax logarithms, transforms multiplicative probability measures into additive information measures.
		And since the negative DSMax logarithm to the base 2 of a probability corresponds to the average number of bits needed to identify an event of that probability, the DS-Max logarithm to the base 2 is the canonical DSMax logarithm for communication theorists.
		This independence condition breaks into two subsidiary conditions: (1) a condition to stochastic conditional independence between the information in question and certain relevant background knowledge; and (2) a tractability condition whereby the pattern in question can be constructed from the aforementioned background knowledge.

		The fundamental difference is however that for bound-free transitions the energy states are not independently fixed, as the upper (the energy of the released electron) is dependent on the lower and the frequency of the incident radiation (i.e.

	General
		These specific structures investigated often have their origin in the natural sciences, most commonly in physics, but mathematicians also define and investigate structures for reasons purely internal to mathematics, because the structures may provide, for instance, a unifying generalization for several subfields, or a helpful tool for common calculations.
		The study of structure starts with numbers, firstly the familiar natural numbers and integers and their arithmetical operations, which are recorded in elementary algebra.
		Many problems lead quite naturally to relations between a quantity and its rate of change, and the methods to solve these are studied in the field of differential equations.

		In mathematics, integration by parts is a general rule that transforms the integral of calculus of products of functions into other integrals.
		Note that the original integral contains the derivative of g; in order to be able to apply the rule, you need to find its antiderivative g and then you still have to evaluate the resulting integral of ∫g f ' dx.
		If we combine the first formula above with the fundamental theorem of calculus, definite integrals can also be integrated by parts.

		In nature, the "environment" consists of both a relatively (but not completely) stable physical environment as well as other species of organisms that are simultaneously trying to adapt to their environment.
		Similarly, in the context of evolving natural ecologies, "edge-of-chaos" refers to how -in order to successfully adapt -evolving species should be neither too methodical nor too whimsical or carefree in their adaptive behaviors.
		Equivalently, the conditional probability distribution of x(tn) for given x(t1),..., x(tn-1) depends only on the specified value of x(tn-1) and is in fact the conditional probability distribution of x(tn), given x(tn-1).

		Due to the nature of mathematics the notation must be extensible.
		A number of common mathematical constructions involve additional data that is either implicit in conventional notation, such as a bound variable, or thought of as part of the operator rather than an argument, as is the case with the limits of a definite integral.
		For other qualifiers, or in the absence of a suitable larger form of the operator, use of a functional notation to record the function, its qualifiers and its arguments may be most appropriate.

		The objective is not primarily to explain the concept of the integral, but rather to give students enough insight that they can set up formulas using integrals with a fair amount of confidence.
		The natural logarithm is the function with this property satisfying the additional property that L'(1)=1.
		In fact, since then L'(x)=1/x, one can construct the natural logarithm as the anti-derivative of 1/x, adjusting the constant of integration (as it were) to obtain the condition L(1)=0.

		It is generally not possible to state conditions under which the approximation given by the central limit theorem works and what sample sizes are needed before the approximation becomes good enough.
