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. …

Sep 10, 2024 · By L'Hospital: The derivative of the denominator is (by pulling one cosine at a time from the product) $$\sum_ {i=1}^n\frac {i\sin (ix)} {\cos (ix)}\prod_ {i=1}^n\cos (ix).$$ This still …

Dec 12, 2025 · We have $$\begin {align*} L &= \lim_ {N\to\infty} \prod_ {n=1}^ {N} \frac {\frac {\pi} {2}\arctan (n)} {\arctan (2n-1)\arctan (2n)} \\ &= \lim_ {N\to\infty} \prod_ {n ...

Oct 23, 2024 · This is not a duplicate of Closed form of $\int\limits_0^ {2\pi} \prod\limits_ {j=1}^n \cos (jx)dx$ and combinatorial link as the following does not apply: As suggested by Winther in …

Nov 1, 2024 · There are simple reasons for the others - it is that $1$ and $4$ are squares of integers.

@DanPetersen: The friend said "the terms in the product" - that is, the numbers being multiplied together - have values less than $1$, and therefore the value of the product can never be $1$. …

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?

Mar 29, 2023 · $$\begin {aligned}Q &= \prod_ { (i,j) \in A} (1-a_ia_j) \\ &= \sum_ {k=0}^ {|A|} \sum_ {S \subset A}^ {|S| = k} (-1)^k\ C_S \prod_ { (i,j) \in S} a_ia_j\\ \end {aligned}$$
