Show that $$\log (n !)=\Theta(n \log n)$$ (Hint: To show an upper bound, compare $n !$ with $n^{n}$. To show a lower bound, compare it with $(n / 2)^{n / 2}$
Determine whether the sequence is increasing or decreasing. Find an upper bound and a lower bound for the sequence: an = 1/2n+3
Let $S=\left\{2,\left(\frac{3}{2}\right)^{2},\left(\frac{4}{3}\right)^{3},\left(\frac{5}{4}\right)^{4}, \cdots,\left(\frac{n+1}{n}\right)^{n}, \cdots\right\}$ (a) Use a graphing utility or CAS to calculate $\left(\frac{n+1}{n}\right)^{n}$ for $n=5,10,100,1000,10,000$ (b) Does $S$ have a least upper bound? If so, what is it? Does S have a greatest lower bound? If so, what is it?
