Why the power is $-\delta^n$ ? Won't it be positive ?

comment Calculate $\int_{-\pi}^{\pi}\prod_{n=1}^\infty \left(1-\frac{t^2}{n^2}\right) e^{-izt}dt$
Can you please tell us what are these "$Ei(-i(z+\pi)t)$" etc and all? The solution is really impressive but I am not able to catch the definitions of these stuff. Thanks

comment Sum of $1+\frac{1}{2}+\frac{1\cdot2}{2\cdot5}+\frac{1\cdot 2\cdot 3}{2\cdot 5\cdot 8}+\cdots$
I think it should be $\prod\limits_{j=1}^k \frac{j+1}{3j+2}$. Otherwise, I am unable to get it

comment Sum of $1+\frac{1}{2}+\frac{1\cdot2}{2\cdot5}+\frac{1\cdot 2\cdot 3}{2\cdot 5\cdot 8}+\cdots$
Jack D'Aurizio Please rectify us the following: $S=1+\sum\limits_{k=0}^{\infty}\prod\limits_{j=0}^k \frac{j+1}{3j+2}$ is not true. For k=1, the first term in the product in your expression is becoming $\frac{1\cdot 2}{2\cdot 5}$.
