Derivatives... How? (NancyPi)

[@arianahouman7914]

Why go to college and get confused for hours when there's a free 15 minutes video that explains everything? We need more teachers like you!

[@shedimale1967]

hahahahahahahahahahahahahaha...that's right!

[@dariansoobramoney8926]

Exactly, she's amazing

[@hughpearson3191]

I agree and disagree.. 3blue1brown video's are much easier to understand and when they show a derivative, they also break it down to real world numbers and come up with.. an ANSWER :) They use sophisticated animated graphs and the presenter has a very very friendly voice.

[@mcorona0710]

I took calculus last semester and had to drop it, too complicated. Gave it another go and stumbled across Ms NancyPi and I'm killing it with a straight A. She helped me understand in less than 20 minutes what I couldn't over an entire semester. Just simply awesome

[@mevadavraj4178]

I think this video is very basic for you as you are university student, if I am wrong don't take me seriously

[@ticskitmusic656]

@@mevadavraj4178 it is, I'm in engineering school but once you've understood these you're kinda good to go, it's somewhat similar to understanding the language of a text book.. So you would learn the basics and then the entire text book is in the language which now, you know. As long as you don't rely completely on this because there are Ln and log rules as well as an entire hell of trigonometry, you're good. All you have to do is look them up and practice

Keep it up! Nobody can buy knowledge.

[@hughpearson3191]

I still recommend 3BLUE1BROWN as an other helpful site. Nancy is good.. really good..but she tends to rely a bit on knowing rules rather than deeply understanding the issue. That's probably a confession about my cognitive abilities though hey :)

[@RachelHannah363]

Like honestly, WHY aren't experienced college professors as incredible as teaching as this young student!?

[@erwinmulder1338]

Because (at least at universities) they are hired for their research skills and not for their educational skills. Contrary to popular belief these are not the same thing. Knowing a lot doesn't automatically mean you can teach it.

[@shedimale1967]

Yeah

[@ronclass1782]

Because it is one of the most stable careers so they don't care

[@hughpearson3191]

haha... maybe because they cannot SPEED write like Nancy when she speeds up the video sometimes ;) Its like she has superpowers eh!

[@juicynugget]

Because they give you the general idea of how to do it and don't elaborate much

[@aleynan2153]

I seriously didn't think I'd ever understand this based on the way my professor taught it but the way you explained it is so simple. Thank you!!!

You're a walking angel. Thank you so much for your videos. I love how you are able to dummy it down. I've literally gotten thru calculus off of just your videos.

[@seaknightvirchow8131]

I am retired. i took calculus 45 years ago and I have forgotten most of it. I have decided to relearn my basic math beginning with algebra and trig. These videos, even calculus, are bringing back so much of what I had forgotten. You are a very good teacher. Somehow these concepts are now easier to understand than when I first encountered them and though part of it is dusting off the once learned material, I think it is also due to how you explain things so clearly.

[@thecosmiccube8178]

If you have the will to learn, then I think you are ought to learn about history, art, psychology, economy, religion, politics and near these topics. I suggest you read books about them. It's better to teach and share knowledge with younger generations so they may improve their life more and take guidance from you. It is easier and more beneficial than math.

I have a library of 3000 books read over a lifetime and it includes all those topics you mention. I encourage my sons and grandchildren to read and I give them books. Besides history, art, philosophy, theology, I love science which is why I am relearning my math. I am comfortable with molecular biology but less so with physics. I can also help my grandchildren with algebra and trig. I think your advice is sound overall, except the math part. 😉

I tried to teach first semester calculus when I was a second year medical student for my community medicine rotation and I must not be a good teacher. I was frustrated the first week after only two classes. To be a teacher of any subject is truly an art and a skill. Time to give teachers their due.
