Errata:

Slides for Video 1.6a contain a small typo (error):  The actual decimal value of 
$1/2^{1/5730}$ is really $.999879$

Slides for Video 4.2 also have a small typo:  The actual equation of the graph we look at
to see local maxima and local minima is y = x^4 - 3 x^3 + 2x   (not y = x^4 - 3 x^2 + 2x)
