Jan 21	comment	Function which gradually rises until some point and then quickly “falls” Thank you! The second modification is what I wanted.
Jan 21	comment	Function which gradually rises until some point and then quickly “falls” Thank you, that's interesting!
Jan 21	comment	Function which gradually rises until some point and then quickly “falls” Thank you for the answer! I meant single function, not piecewise.

Jan 21	comment	Function which gradually rises until some point and then quickly “falls” @IanMateus That is not necessary.

Nov 24	accepted	Proof of sequence limit, using epsilon-delta method.
Nov 24	comment	Proof of sequence limit, using epsilon-delta method. Thank you, I hope I finally figured it out with the priceless help of SE mathematicians. :)
Nov 24	comment	Proof of sequence limit, using epsilon-delta method. Thank you! One elaboration: is ${\lceil\frac{1}{\epsilon^2}\rceil}$ means integer part without rounding it or it is the next integer, which is larger or equal to ${\frac{1}{\epsilon^2}}$?
Nov 24	comment	Proof of sequence limit, using epsilon-delta method. Thank you for such a consistent and complete answer!
Nov 24	comment	Proof of sequence limit, using epsilon-delta method. @alex.jordan Yes, ${n}$, sorry, just a typo. I have corrected it.

Nov 24	comment	Why ${ \sum\limits_{n=1}^{\infty} \frac{1}{n} }$ is divergent , but ${ \sum\limits_{n=1}^{\infty} \frac{1}{n^2} }$ is convergent? thank you again, i think I understood. :)
Nov 24	comment	Why ${ \sum\limits_{n=1}^{\infty} \frac{1}{n} }$ is divergent , but ${ \sum\limits_{n=1}^{\infty} \frac{1}{n^2} }$ is convergent? Thank you! I've understood "telescoping sum", but could you please explain what gives "comparison" for the first series? I can't see any significant difference between ${\frac{1}{n^2}}$ and ${\frac{1}{(n-1)n}}$
