Infinite Series

The goal of the talk is to see how the 28 year old Euler in 1735 solved a problem known as the Basel Problem. This problem had been proposed by Jakob Bernoulli in 1689 when he collected the all of the work on infinite series of the 17th century in a volume entitled "Tractatus De Seriebus Infinitis". Bernoulli's comment in this volume was that the evaluation ``is more difficult than one would expect''. Little did he know how difficult it really was, and that it would take almost 50 years for the problem to be solved. This problem is highlighted in the first volume of Polya's "Mathematics and Plausible Reasoning, Volume 1" in his discussion on the use of analogy leading to discovery. It is this method of `solving' the problem that this talk will address. Along the way we will discuss many of the items touched upon at a more advanced level last week in Andrew's talk on generating functions; geometric series, telescoping series, and Maclaurin series.
