This video was very helpful! I am taking an online Social Research class
and we have no actual class time. There was only one video on the site
showing how to distinguish between the levels of kurtosis and skewness. We
are pretty much expected to learn independently. Thank goodness for
YouTube!
Moment Generating Functions for Uniform Distributions
Probability: We compute the moments (about the mean) for a random variable with a uniform probability distribution. We calculate both directly and by using the ...

Exactly what I was looking for. (Who wants to do L'Hopital's Rule anyway?)
The audience for this kind of video is surely limited, but for those of us
who need it, a well produced lecture is gold! You explained all the things
that snobby textbooks call "obvious." Since I don't have every power series
memorized... Thank you! One suggestion, from a rhetorical perspective, is
to be mindful of your inflection. Every statement ends with your voice
moving up (as one would when asking a question).

You're welcome! Good teaching requires constant repetition and review, and
trying to attain a beginner's mindset. I talk a mile a minute naturally, so
here I feel like I'm constantly pumping the brakes. Some voice/acting
lessons and a teleprompter would do wonders.

Your videos, especially the calc videos, are far better than others ive
seen. Not because you explain things more comprehensively, but because you
give better examples.
