   What if p x a is bounded above?

   • (∀x ∈ A) p ≤ x A is bounded above (or right bounded) iff there is q ∈ F such that (∀x ∈ A) x ≤ q In this case, p and q are called, respectively, a lower (or left) bound and an upper (or right) bound, of A. If both exist, we simply say that A is bounded (by p and q).

   Are P and q bounded?

   • In this case, p and q are called, respectively, a lower (or left) bound and an upper (or right) bound, of A. If both exist, we simply say that A is bounded (by p and q). The empty set ∅ is regarded as ("vacuously") bounded by any p and q (cf. the end of Chapter 1, §3). The bounds p and q may, but need not, belong to A.

   How do you find bounded properties?

   • The standard English terms are "bounded from above" and "bounded from below". Corrected, cheers. If you just want the bounded property, you can simply find crude upper and lower bounds. E.g. if (−1)n + 1/n (− 1) n + 1 / n is bounded, then so is ((−1)n + 1/n)2 ((− 1) n + 1 / n) 2 (so we can essentially disregard the power of 2).

   Is a series bounded above?

   • an ≤ 1 + 1 2 + 1 4 + 1 8 + ⋯ + 1 2n−1 < 2. series + +. So definitely bounded above. You are probably referring to + + + 1 4 + 1 5 + (the series), which does diverge. @Jamil_V: No. Finding a smaller sequence that is not bounded above is a way to show that a given sequence is not bounded above. This is finding a larger an =∑k=1n bk ≤∑k=1n (1 3)k.

   Every nonempty subset \(A\) of \(\mathbb{R}\) that is bounded above has a least upper bound. That is, \(\sup A\) exists and is a real number. This axiom distinguishes the real numbers from all other ordered fields and it is crucial in the proofs of the central theorems of analysis.

    5 days ago · Bounded from Above. A set is said to be bounded from above if it has an upper bound. Consider the real numbers with their usual order. Then for any set , the supremum exists (in ) if and only if is bounded from above and nonempty.
