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 be bounded
, , , and be bounded
, , , and be bounded
, , , and
, , , and
, , , and be 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 where represents the upper integral and the following are defined:
1. The upper integral of on is
where is a partition of .
2. The lower integral of on is
where is a partition of .
3. If 1 and 2 are the same then the integral is said to be
if and only if , , , and be bounded.
Therefore the necessary condition for the proving the upper and lower integrals of a bounded function exists is if and only if , , , and be bounded.
Example Question #2 : Riemann Integral, Riemann Sums, & Improper Riemann Integration
What term has the following definition.
, and . Over the interval is a set of points such that
Partition

Refinement of a partition
Lower Riemann sum
Upper Riemann sum
Partition
By definition
If , and .
A partition over the interval is a set of points such that
.
Therefore, the term that describes this statement is partition.
Example Question #3 : Riemann Integral, Riemann Sums, & Improper Riemann Integration

Norm
By definition
If , and .
A partition over the interval is a set of points such that
.
Furthermore,
The norm of the partition
is
Therefore, the term that describes this statement is norm.
