Book vs. Internet
Looking in the book, I found that the definition was very concise and easy to understand. Unlike the site that I found which took time to watch and absorb all of the information as it flashed by on an animation. In the Presentation that was dragged on for several minutes I learned the same amount as in the two line definition box in the book. It is also a lot easier to understand an elementary explanation than a huge production with lots of distractions.
Definition:
if f(x) = u•v then f'(x) = u'•v + u•v'
Examples:
f(x) = 3x^2 • lnx
f'(x) = (6x • lnx) + (3x^2 • 1/x)
f'(x) = (6x • lnx) + (3x)

I think this is a really helpful post and the example is really easy to understand. I like that you included the video that you compared the book explanation to because even if the person reading this post doesn't understand the book, the link to the video is right there. Do you think that we could learn more in class if we worked out of the textbook instead of watched demonstrations?
