May 9	accepted	Which value of $k$ in $e(k) = 5$ where $E(z)=5z^{-1}+z^{-2}+2z^{-4}$?

Apr 17	comment	Proving that $L\{e^{at}\} = \frac{1}{s-a} s>a$ According to bit.ly/111XHei line 2 should simply become $e^{-B(s-a)}$. I still don't get where the denominator comes from or the "-1" in the numerator in line 4?

Nov 20	accepted	Am I correct if I say $\lim_{n\rightarrow\infty}\sum_{k=1}^n\frac{\sqrt{k}}{(k+1)^2}$ converges?

Nov 19	revised	Find the sum of the first $n$ terms of $\sum^n_{k=1}k^3$ rolled back to a previous revision
Nov 19	accepted	Find the sum of the first $n$ terms of $\sum^n_{k=1}k^3$
Nov 18	comment	Find the sum of the first $n$ terms of $\sum^n_{k=1}k^3$ @Gautam Shenoy: Why would I randomly try to expand $(k+1)^4$? I have an example in my book that I just found doing the same thing for $\sum_{k=1}^nk^2$ where they then expand $(k+1)^3$. Where does this come from?
Nov 18	comment	Find the sum of the first $n$ terms of $\sum^n_{k=1}k^3$ @user49521: What is special about n=4?
