Example Question #1 : Induction
Determine whether the following statement is true or false:
If is a nonempty subset of , then has a finite infimum and it is an element of .
True
False
True
According to the Well-Ordered Principal this statement is true. The following proof illuminate its truth.
Suppose is nonempty. From there, it is known that is bounded above, by .
Therefore, by the Completeness Axiom the supremum of exists.
Furthermore, if has a supremum, then , thus in this particular case .
Thus by the Reflection Principal,
exists and
.
Therefore proving the statement in question true.
Example Question #1 : Sequences In Real Numbers (R)
What term does the following define.
A sequence of sets is __________ if and only if .
Nested
Increasing
Bounded
Unbounded
Decreasing
Nested
This statement:
A sequence of sets is __________ if and only if
is the definition of nested.
This means that the sequence for all elements, for which belongs to the natural numbers, is considered a nested set if and only if the subsequent sets are subsets of it.
Other theorems in intro analysis build off this understanding.
Example Question #1 : Intro Analysis
Determine whether the following statement is true or false:
Let , , , and . If and then .
True
False
False
Determine this statement is false by showing a contradiction when actual values are used.
Let
First make sure the inequalities hold true.
and
Now find the products.
Therefore, the statement is false.
Example Question #1 : Intro Analysis
What conditions are necessary to prove that the upper and lower integrals of a bounded function exist?
, , , and
, , , and
, , , and be bounded
, , , and be bounded
, , , and be bounded
, , , 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
