Oddly enough I've already seen this video. For some reason youtube thinks this video is relevant to the Taylor and McLaurin Series.

Yes I use youtube to learn Multivariable Calculus since I never go to class. It's surprising how much better a teacher these teenagers are that post videos than my teacher of 20 years. One explanation is that I go to the videos when I want, whereas class is held during the day when I don't want to go. Another is that she's female . Zing! I couldn't pass that up.
