answered equivalency of the least upper bound property & convergence of every monotone and bounded sequence in $\mathbb{R}$

answered find distribution of $\max(x^2,x)$ and $\min (x,1)$

comment find distribution of $\max(x^2,x)$ and $\min (x,1)$
@DavidG.Stork Its the distribution function, not the density. $X$ is uniformly distributed over $[0,2]$.

comment Show that $f$ is continuous at exactly one point
This follows from the very definition of convergence for a sequence.

comment Show that $f$ is continuous at exactly one point
No, you haven't, you can stick to sequences if you like and expanding your proof. I'll be more concrete on this.

comment Deterministic condition for the nature of one real root of a cubic equation
As the OP asks for one, not the, real root, you are not restricted to the case you consider. The Sign of $a$ and $d$ tells you the sign of one real root.
2d
answered Defining a function by right limits
2d
reviewed Approve Show that f: $\mathbb{R}$/$\mathbb{Z}$ $\to$ $\mathbb{R}$/$\mathbb{Z}$ orientation reversing. Then f(x) = x has exactly 2 solutions.
2d
reviewed Approve For $N\in \mathbb{N}$, do there exist natural numbers $N<n_1<n_2<\cdots<n_k$ such that $\frac{1}{n_1}+\cdots+\frac{1}{n_k}=1$?
2d
comment Show that $(x^3+2x)/(2x+1)$ is $O(x^2)$
For what asymptotic limit? $x \to \infty$, I suppose?
