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 …

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 …

Apr 13, 2016 · We assume that $\sum |a_n|^ {2}$ converges, then I want to conclude that $\prod (1+a_n)$ converges to a non zero element $\iff$ the series $\sum a_n$ converges.

Nov 1, 2024 · This question shows research effort; it is useful and clear

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 ...

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 …

The log of a product is the sum of logs of the things inside the product. So
