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.

where are u now

@@systematic3550 interesting question

[@NewWesternFront]

did he ded

me currently: (i study at mapua iykyk)

[@stillbeatz]

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

[@RebootedMind]

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

[@tomjong4141]

he is 100 times better than my math professor at college

[@jaredmorales9763]

Amazing vid may have saved my career !

[@keitogamingyt2764]

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

[@wizardengineer]

+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.

[@rohankhubchandani3694]

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

[@WiperTF2]

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

Baie dankie!!!

[@kayatsa]

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

[@NewWesternFront]

lol microtransactions in textbooks now??

[@sighingandcryingforjerusal2115]

powerful u are too helping

[@Leighton4Ya]

amazing drawing tbh

[@karyuetng6296]

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

[@HecTicAir]

you're a wizard

That's my name.

[@thomasnelles5827]

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