Optimization: cost of materials | Applications of derivatives | AP Calculus AB | Khan Academy

With all the storage you might have to handle for your shoe factory, I bet you'd also like to be able to minize the cost of storage. Created by Sal Khan.

AP Calculus AB on Khan Academy: Bill Scott uses Khan Academy to teach AP Calculus at Phillips Academy in Andover, Massachusetts, and heÕs part of the teaching team that helped develop Khan AcademyÕs AP lessons. Phillips Academy was one of the first schools to teach AP nearly 60 years ago.

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.

wtf i just realized my math quiz last week had this exact question & i didnt know how to do it lol. i guess my professor watches khan academy

+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.

he is 100 times better than my math professor at college

This is a good one :) i need to review this kind of questions for our Calculus 1 🤣

Amazing vid may have saved my career !

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

[rohankhubchandani]

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

[kayatsa]

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

[karyuetng]

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

[Izhueful]

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

[louisetiongson]

how do you solve this when the dimensions of the box are not given?

[thomasnelles]

The fact that my teacher gave us the exact same question is hilarious to me
