Infinite product

In mathematics, for a sequence of complex numbers a1, a2, a3, ... the infinite product is defined to be the limit of the partial products a1a2...an as n increases without bound. The product is said to converge when the limit exists and is not zero. Otherwise the product is said to diverge. A limit of zero is treated specially in order to obtain results analogous to those for infinite sums. Some sources allow convergence to 0 if there are only a finite number of zero factors and the product of the non-zero factors is non-zero, but for simplicity we will not allow that here. If the product converges, then the limit of the sequence an as n increases without bound must be 1, while the converse is in general not true. The best known examples of infinite products are probably some of the formulae for π, such as the following two products, respectively by Viète (Viète's formula, the first published infinite product in mathematics) and John Wallis (Wallis product): (Wikipedia).

Infinite Limit Laws

Infinite Limit Laws In this video, I illustrate the definition of an infinite limit by proving the infinite product rule: If sn goes to infinity and tn goes to t (positive), then sn tn goes to infinity. Other examples of limits can be seen in the playlist below. Definition of a Limit:

An Infinite Product Conjecture - Monday Math Nugget #2

Today we're answering a question posed in the comment section of the previous MMN... The conjecture is: since any quotient of finite products of integers cannot be an integer if all factors in the numerator are odd and at least one in the denominator is even, then a quotient of infinite

Epsilon delta limit (Example 3): Infinite limit at a point

This is the continuation of the epsilon-delta series! You can find Examples 1 and 2 on blackpenredpen's channel. Here I use an epsilon-delta argument to calculate an infinite limit, and at the same time I'm showing you how to calculate a right-hand-side limit. Enjoy!
