@[USERNAME]The Khanacademy ones do give you the intuition but the ability to derive them, at least for me, brings this one over the top.While Mr. Khan is great at giving you intuition, I think it is much better for you to be able to derive the equations in order for you to get the intuition.Also he doesn't tell you how to derive anything, other than a few instances.(From what I have seen.)####[['Khanacademy', 'Course_General_Feedback', 'NEG']]
