Chapter 9 Videos — Sequences and Series of Functions

TAYLOR SERIES

This is the excellent video on Taylor series that I kept pestering you to watch in Section 9.9.  Given an infinitely differentiable function f, this video describes how to construct polynomials that approach f.

UNDERSTANDING E TO THE I PI IN 3.14 MINUTES

This short video gives a good way to think about why  e^iπ equals -1.  It of course involves imaginary and so leaves the realm of real analysis, but not in any way that you can't handle.  A second video on this topic by Mathologer is here.

This equation was deduced in the final section of the book as a consequence of Taylor series.

Future Analysis Topics

VISUALIZING THE RIEMANN HYPOTHESIS

The Riemann Hypothesis is one of the great unsolved problems in mathematics.  It was mentioned on page 53 of the text, but not stated or discussed.  This is an excellent video discussing it.

THE HEAT EQUATION

The Heat Equation is currently an important and active research topic in analysis.  This video is a great introduction to this field.

A Surprising Appearance of π

Check out this video for a surprising appearance of π in a physics problem.  Throughout the discussion you'll notice several tools discussed in real analysis.

PROVING A NUMBER IS TRANSCENDENTAL

A number is algebraic if it is the root of some polynomial with integer coefficients, and it is transcendental if it is not.  Showing a number is irrational is one thing, but showing it is transcendental is often much more difficult.  This video discusses how one might try to prove that e and π are transcendental.
