	Wikipedia: Integral
		In particular, for a constant function, the integral is defined as its constant value times the measure of the region on which it is defined; in this basic case, the integral is just the area of a rectangle (in one dimension) or volume of a prism or cylinder (in two dimensions).
		The integral of a general function is then defined as the limit of the easily-calculated integrals of a sequence of simpler functions.
		Its integral is the size of the area bounded by the x-axis and the graph of a function, f(x); negative areas are possible.

	Integral - Wikipedia, the free encyclopedia
		Intuitively, the integral of a continuous, positive real-valued function f of one real variable x between a left endpoint a and a right endpoint b represents the area bounded by the lines x=a, x=b, the x -axis, and the curve defined by the graph of f.
		Improper integrals usually turn up when the range of the function to be integrated is infinite or, in the case of the Riemann integral, when the domain of the function is infinite.

	Integral - WikipÃ©dia
		An integral which can only be evaluated by considering it as the limit of integrals on successively larger and larger integrals is called an improper integral.

	Haar measure
		In mathematical analysis, the Haar measure is a way to assign an "invariant volume" to subsets of locally compact topological groups and subsequently define an integral for functions on those groups.
		Haar measures are used in many parts of analysis and number theory.

	Haar Wavelets
		Haar discovered the wavelets which are called after him around 1909, before wavelets where discovered.
		In the same way, Haar wavelets have been constructed on spaces with measures which are not translation-invariant (as Lebesgue measures).
		Ok, with Haar wavelets one can approximate to the desired level of accuracy in all these senses, if the function to be approximated is "reasonably good".

	Integral: Definition and links.
		The integral value of a real number x is defined to be the largest integer which is less than or equal to x ; it is often denoted by ⌊ x ⌋ and also called the floor function.
		In the integral calculus, the integral of a function is informally defined as the size of the area delimited by the x axis and the graph of the function.
		Both the Riemann and the Lebesgue integral are approaches to integration which seek to measure the area under the curve, and the overall schema in both cases is the same.

	Henri Lebesgue Summary
		The integral, which relates to the limiting case of the sum of a quantity that varies at every one of an infinite set of points, is fundamental to the study of calculus.
		The Riemann integral had been generalised to the improper Riemann integral to measure functions whose domain of definition was not a closed interval.
		Although Lebesgue's integral was an example of the power of generalisation, Lebesgue himself did not approve of generalisation in general and spent the rest of his life working on very specific problems, generally in mathematical analysis.
