Example Question #1 :Riemann Integral, Riemann Sums, & Improper Riemann Integration
What conditions are necessary to prove that the upper and lower integrals of a bounded function exist?
,,, and
,,, andbe bounded
,,, andbe bounded
,,, and
,,, andbe bounded
,,, andbe bounded
Using the definition for Riemann sums to define the upper and lower integrals of a function answers the question.
According the the Riemann sum whererepresents the upper integral andthe following are defined:
1. The upper integral ofonis
whereis a partition of.
2. The lower integral ofonis
whereis a partition of.
3. If 1 and 2 are the same then the integral is said to be
if and only if,,, andbe bounded.
Therefore the necessary condition for the proving the upper and lower integrals of a bounded function exists is if and only if,,, andbe bounded.
