Can an integral not exist
WebExamples. The original definition of the Riemann integral does not apply to a function such as / on the interval [1, ∞), because in this case the domain of integration is unbounded.However, the Riemann integral can often be extended by continuity, by defining the improper integral instead as a limit = = (+) = The narrow definition of the Riemann … Web1. A line. The applet initially shows a line. We want to know whether has a value. Symbolically, we would do the following: This last limit does not exist because it is unbounded. We can see this from the applet, which shows a table of values for the integral for different values of b.As b gets bigger, so does the value. You can also see this from …

If the limit is finite we say the integral converges, while if the limit is infinite or does not exist, we say the integral diverges. Convergence is good (means we can do the integral); divergence is
WebOtherwise, we say the improper integral diverges, which we capture in the following definition. Definition 2.53. Convergence and Divergence.
