Calculus - Finding the derivative of a function using limits

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

thanks

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

perfect

ThX

best!

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.

moar!!

ugh expanding that is a mess

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

omg use power rule

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

тиχ вυ∂∂у 😊

Thank you.

so easy straight forward

Just amazing bro, thanks a lot

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. 💜

He's like Bob Ross for calculus

Thank you!

❤️

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

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

I wish my professor taught as well as you

To infinity and beyond through these definitions

thanks

Great refresher. Thank you.

Hi! A secant is a line that intersects a curve at a minimum of two distinct points,whereas a tangent line is defined as the unique line that touches a curve at only one point so a secant line will never look like a tangent line therefore the differentiation never gives us actual slope of a curve.
