Derivatives... How? (NancyPi)

Started studying mathematics after 15 years for my PhD economics courses, and your videos are truly the saviors for me. You explained in a brilliant way, thumbs up.

I know this is an old video but five years later it feels so new....

I was so excited when I watched what you taught. Everything is simple under your teaching way. but I have a problem that i don't know how you write and what your board is?

WOW!!! THIS SEEMS LIKE "MAGIC"... NOW, WHAT DO THESE PARTICULAR "EQUATIONS" REPRESENT??!!!... WHAT DOES ALL OF THIS HELP US DO, TO RELATE TO THE REAL WORLD?!!...

Crystal clear teaching.........👍

Nancy Plz give some update about you

people like u have a special place in heaven, my professors be making up their own lexicon and take 45 mins to explain a simple concept.

Wow it’s very well

Thanks it helps me a lot in solving the derivative questions!

Good teacher she deserves a place in heaven

Any chance anyone has free notes relating to all of calculus? (Ideally based upon Nancy's videos)
