i am asked to find a marginal cost function from a cost function [ c(x)= 600+ root of (50+15x²)], but what if the derivatives results only in a single real number? Can i say my marginal cost function is undefined?

ok, so I am trying to learn calculus off of online teacher’s notes, and I had a question about finding the derivative of a right cone. In the equation, (” π * (c^2) * (h^2) ” what does the c stand for?

It would have been more proper to have nullified the square root in the denominator of square root x times 2 by multiplying the numerator and denominator by square root of x right at 5:47

I appreciate the video. I am a Physics major currently in both Calculus I and Calculus based Physics. I need the derivatives knowledge right now for my Physics work, but haven’t got to that point in my Calculus class yet(still just doing limits), so this video helped me a lot.

You have amazing Microsoft paint handwriting.

iphone or ipad app for derivatives:

My math teacher at the university doesn’t teach as well as you. You helped me a lot!

U r the best!

very good teaching man.

@bigfatgreenguyinrain t’es le bienvenue

@kroooassant Thanks man, that clears that up a lot!

@bigfatgreenguyinrain c means constant. for example in 3 g(x); 3 is the constant.

that means that, that means that, that means that

Awesome. Thank you so much.

I am so happy to find this on youtube! I will look forward to seeing your videos whenever i need help in AP Calculus or AP Physics XD

very good I liked it thx

Ill ask something, its about implicit differentiation, from d/dx, how did it become dy/dx..?? I hope you’ll answer it.. Thank you very much

@kevinxanderful Thanks for the compliment

Okay, so all this being said, what exactly is a derivative?

I cant follow my professor’s teaching. Good to know about this in youtube..

@survivor0426 Your welcome Good luck on the test!

I’m studying for a Math certification test for teaching and this was super helpful! Thanks:)

@HarRonHer7 I am glad I could help This is what I do for a living so unfortunately the live tutoring is not free

Very helpful are your one on one tutorials free?

@edanguitarist Appreciate the compliment
