      I don’t think you’re professor knows how to do it either if he’s using Khan Academy examples😂😂😂

    I just learned about it this year. It's great that he uploaded these videos since my math teacher is horrible and i already live 1 hour 30 minutes away from my school because there aren't any good schools around me and i travel that distance twice everyday so i can be taught by a bad math teacher but good teachers in other subjects. This is literally a life saver. I love you, sal.

    +Khan Academy Wouldn't you just want to use Video tags so that you can be one of the more posted/searched channels on the youtube list? If you would like to do this it would be nice for helping more people out with their education in Math, Algebra, Geometry, Pre-Calculus, and Calculus? If you are truly not into that then it's okay. I just hope you can continue helping kids, teens, and college students.

    could you plug back in x and h into the original equation for cost instead of finding the second derivative?

    Is there a direct link to the youtube playlist with Differential Mathematics?

    nice art skills
    my textbook had the same exact problem but no answer (unless you pay extra) so thank you

    Recently learned about this in school. Differential math right? Optimization. It's so useful and such a great feel to figure it out ! :)

    6:36 wait... should the C(x) equation at the bottom have x to the -2 power instead of -1 at the end??

      there is an X to the right of the 36 in the multiplication.
      (X^1) / (X^2) = X^-1
