Unbounded integral
In mathematical analysis, an improper integral is the limit of a definite integral as an endpoint of the interval(s) of integration approaches either a specified real number or positive or negative infinity; or in some instances as both endpoints approach limits. Such an integral is often written symbolically just like a standard … See more The original definition of the Riemann integral does not apply to a function such as $${\displaystyle 1/{x^{2}}}$$ on the interval [1, ∞), because in this case the domain of integration is unbounded. However, the … See more There is more than one theory of integration. From the point of view of calculus, the Riemann integral theory is usually assumed as … See more One can speak of the singularities of an improper integral, meaning those points of the extended real number line at which limits are used. See more Consider the difference in values of two limits: $${\displaystyle \lim _{a\to 0^{+}}\left(\int _{-1}^{-a}{\frac {dx}{x}}+\int _{a}^{1}{\frac {dx}{x}}\right)=0,}$$ The former is the … See more An improper integral converges if the limit defining it exists. Thus for example one says that the improper integral $${\displaystyle \lim _{t\to \infty }\int _{a}^{t}f(x)\ dx}$$ exists and is equal to L if the integrals under the limit exist … See more In some cases, the integral $${\displaystyle \int _{a}^{c}f(x)\ dx}$$ can be defined as an integral (a Lebesgue integral, … See more An improper integral may diverge in the sense that the limit defining it may not exist. In this case, there are more sophisticated … See more WebWhat is the best integral calculator?

WebDefinition of Lebesgue Integral. Let f: E → R be a bounded function and E be a measurable set of finite measure. Then we may have the numbers. inf 𝜓 ≥ f ∫ E f(x) dx and sup 𝜙 ≤ f ∫ E f(x) dx,. where 𝜓 and 𝜙 are simple functions over measurable set E. These two numbers exist and are respectively called upper Lebesgue integral and lower Lebesgue integral.
