    I know Dr. Jerison won't be able to see this comment, but I just really want to say that, even though Dr. Jerison probably have vaguely guessed his impact from this Calculus course. But he would never know how MANY chinese students have their calculus SAVED by him. In fact this MIT OCW project has world impact, it will be a monument of the early Internet age

    Honestly I think there should be people moderating the comments section that delete those judgmental comments. The students have rights to learn in a safe environment. Asking “stupid” questions is an integral part of learning as much as making mistakes. It’s just sad to see students swallow their doubts bcs they worry about how they look in front of others.
    So if you know the answers to the questions, shut up and watch the video without being a judgmental jerk.

    To everyone being rude to the student, he's actually not completely off like you wrongly assume. Because if you have parentheses around the number in the superscript/exponent it can be used to denote a higher order derivative, like f⁽⁵⁾(x) can be used instead of the much less readable f'''''(x).

      I think you're supposed to use greek numerals to denote derivatives. So it would be f^{V}(x)

    For surface area the rotation method will not do , in mu opinion

    Great video, but misleading title. "Parametric Equations" in the name, and 40/45 minutes are about arc length and surface area? I kept waiting for the Parametric Equations topic to kick in I didn't realize the video was almost over.

    • @lpereira95
      @lpereira95 5 років тому

      I guess that if you rotate your axes in order to align one of the new coordinate-axis with the axis of revolution, you'll be able to easily solve the problem using the already-known strategy.

      @jpnewshazaribagh8130 4 роки тому

      It has been given in the previous lectures to find volume aboit x and y axis. Volume of rotation.. And u can just make a change of axis. It is messy but we can solve it if we have a lot of patience.

    I obviously don't know as much maths as Prof David, but isn't the illustration (I call it illustration) between relationship of arc length of circle,# and angle circular? The arc length, in standard trig or elementary calculus, is already DEFINED. Further, to arrive the the arcsin, the trigonometric derivation trick was used. So proof is circular. But it is good demonstration of geometric interpretation.
    This "proof" reminds me of attempt to define addition using sets and powersets. Interesting but not useful for all practicle purpose.

    Yeah theres an equivalent notation in the function notation two but it contains parentheses f^(2) (x) (the 2's little), yeah nothing much, just thought it was funny, but it does happen- smart people can derp moment sometimes XD.

    the confusion arises from leibniz notation where d^2/dx^2 would represent the second derivative. still pretty dumb question though aha

    Am I the only one who doesn't seem think mr jerison isn't a good teacher? I mean compared to the brilliant herbert gross and christine breiner he seems to not be able to connect with us students and get what might be difficult or need more to students. In one of the lectures he couldn't even understand that the student who asked a question had a problem with negative numbers n that's the freakin basics .. PS I totally get this a purely subjective thing.
