calculus - Prove $\prod\limits_ {i=1}^n (x_i^n+1)\geq 2^ {n}$ for ...
5 days ago · One way, I guess to see this, is that this procedure fixes $\prod_ {i=1}^nx_i$, and when taking the logarithm is equivalent to the averaging process. Thus, we get the result.
Is $\mathop {\Large\times}$ (\varprod) the same as $\prod$?
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. …
trigonometry - Prove that $\prod_ {k=1}^ {n-1}\sin\frac {k \pi} {n ...
Thus, if we apply Kirchhoff's theorem, we get $$\prod_ {m=1}^ {n-1} 4\sin^2 (\frac {m\pi} {n}) = n^2.$$ By taking square root and dividing both sides by $2^ {n-1}$, we get the desired formula.
