Calculus - Finding the derivative of a function using limits

[NimbleSF]

You're so infinitely helpful, man. You speak in a way that is so easy to understand and explain things very clearly and concisely. You helped me understand 2 weeks of 6 hours of calculus in less than an hour. Thank you very much.

You taught me something in 1.03 minutes that my Professor still hasn't fully explained to me in the 6 weeks I have had him. 💜

Thank you so much man. I saw the video from the computer and i used my cell phone because it has my google account and look for your channel just to thank you and like your video. Because you spend time to help us . So thank you

[RyleZor]

Thank you so much, this was almost exactly the problem I had to solve and it was explained perfectly. :D

To infinity and beyond through these definitions

Thank you so much! That was easy to understand!!

I wish my professor taught as well as you

I got a question? Why on 1:32 did you write 3xh² ...esoecially after you took the cube and already did 3x²h.. ??

[marisolrubalcava]

What if the h doesn’t cancel out at the bottom?

with at least this specific problem it would have been so much faster just using chain rule

that’s a long way just find the derivative of f(x) and that’s it
