    It is exam time and Khan Academy is clear and understandable. I waited too long for this help, but I am confident I can save my grade. Thank you for all you do. I will pay it forward.

      GidZk , Probably, he failed badly. Some people on earth are so dimwitted that they don't deserve to learn mathematics of this level.

      Imroz zahan. Or maybe he doesn't use this account anymore? Maybe he did pass with a low grade? Or maybe he averaged the test and doesn't want to share his mark? I don't see how someone as insignificant as yourself in this society can determine who deserves to learn what.
      Seriously, keep your opinion to yourself.

    • @lickheaddarry9123

      My professor is actually solving the problem himself. He just keeps on writing stuff on the board. Asked for explanation, explanation is too complicated.

  • @Damianthefallen1
    @Damianthefallen1 12 років тому +2

  • @ericsupple3870
    @ericsupple3870 11 років тому +1

    You have truly made this easy. I bought "Calculus for Dummies", which is very thorough (for the most part) on explaining how to do things. There are some ways that they can make it easier, and your video definitely filled in the blanks that were left after reading that book. THANK YOU!

    I think this world is a mess! Hear me out here: I am a BA candidate in computer engineering but had to come here for some refreshing as I was somewhat struggling with cal 3 (because I hadn't really done any math in more than five years really). But my point is, I've stumbled upon ridiculous videos on youtube of some hip-hop or some other junks with million plus views. And then to know these treasures are sitting right here free of charge? Wow! I mean, I'd already made my minute donation to your website and I thank you from the bottom of my heart, but I really feel pessimistic about my world..or at least about my country. I pray I'm wrong.

  • @B.A.512
    @B.A.512 8 років тому +7

    I really like to do this. Some coffey on the table and pause a equation just before the answer is coming. Then I try to solve the mathematical problems myself and see if it is correct. It is not a shame to make mistakes... I mean, people remember bad things the best right? So you'll never forget to do it the right way after some shots :)

    It often comes down to whether or not the needed resources are available to us though. Khan Academy is great but even it doesn't have everything quite yet.

    They say that the US education system is flawed because it's the student's fault, never the teachers. If this is true, Then why do I find his videos much more understandable and more interesting than a lot of proffessors?

  • @Ignovola
    @Ignovola 14 років тому

    @markkeng He didn't make an error. It should be -4 because when finding the antiderivative the exponent should be raised by 1. Don't let negatives confuse you ^^

    Great thing about this channel is that you can donate how much you want to. If you think this is worth the money (indeed it is), you can donate quite big amount of money, and if you dont think (i don't think there is any :P) you just ignore it. I would donate for kahn instead of paying for overpriced books that cost like 100 bucks each. its ridiculous.

    If the curve is defined by unknown functions, how could I find the total area under the curve?
    Would I split the curve into multiple curves which match a set function profile, find the area for each, and then "stitch" the set together?
