Can you give the context in which you've found this symbol? Π Π is frequently used for products, and ∐ ∐ is frequently used for disjoint unions or for coproducts.

DevOps engineers are those who are good at debugging, troubleshooting, analyzing prod issues and providing solutions. Who have good hands on technologies like unix shell scripting, perl, SQL etc.

At first I thought this was the same as taking a Cartesian product, but he used the usual $\prod$ symbol for that further down the page, so I am inclined to believe there is some difference. Does anyone …

Sep 13, 2016 · Compute:$$\prod_ {n=1}^ {\infty}\left (1+\frac {1} {2^n}\right)$$ I and my friend came across this product. Is the product till infinity equal to $1$? If no, what is the answer?

May 8, 2014 · I've been looking at proofs of Euler's Sine Expansion, that is $$ \frac {\sin\left (x\right)} {x} = \prod_ {k = 1}^ {\infty} \left (1-\frac {x^ {2}} {k^ {2}\pi^ {2 ...

Dec 6, 2022 · Consider the functions f(x) = ∏∞ n=1(1 −xn) f (x) = ∏ n = 1 ∞ (1 x n) and g(x) = ∏∞ n=1(1 +xn) g (x) = ∏ n = 1 ∞ (1 + x n) f(x) f (x) is defined for x ∈ [−1, 1] x ∈ [1, 1] and g(x) g (x) is defined for …

My solution is the same, and the answer your question, the key is CONTINUITY. This is a common trick in algebra (and often in linear algebra) where you have to prove that a giant polynomial expression …

Jan 3, 2021 · How can I prove that $$ \prod_ {n=1}^ {\infty} \left (1+\frac {2} {n}\right)^ {\large { (-1)^ {n+1}n}} \,= \frac {\pi} {2e}$$ The result is given here (result 48).

Jun 29, 2020 · By definition, an infinite product $\\prod (1 + a_n)$ converges iff the sum $\\sum \\log(1 + a_n)$ converges, enabling us to use various convergence tests for infinite sums, and the Taylor …
