Infinite Limits & Infinite Series

Infinite Limits & Infinite SeriesMike MadroInfinite LimitsIs a list or set of numbers written in definite order.T1/2, t2/3, t3/4, t4/5, ..., tn,In an infinite sequence each term has a successor As a sequence approaches a number such as 1 , we can say that the limit of the sequence is 1 Infinite SeriesIs the adding of an infinite amount of numbers In which we allow Sn to represent the sum of the terms in the series Ex. Sn= 0.5+0.25+0.125+0.0625As we add more terms to the series the sum gets closer to 1, therefore we can assume that the sum of the infinite series is 1If a series has a sum, it is called a convergent series. If not, it is called divergent.

Real WorldZenos second paradox involves a race between the Greek hero Achilles and a tortoise. In this problem Zeno argues that at Achilles start position a1 and the tortoise start position t1, when Achilles reaches point a2=t1 the tortoise will be ahead at position t2. Therefore, at position a3=t2 the tortoise will still be ahead at t3. This process should continue indefinitely.

Real World Infinite SeriesIn another of Zenos paradoxes: a man is not able to walk into a wall because he would always be going half the distance. This halving of distance would continue indefinitely.
