@@ThinknSpeak I'm not responsible for your education, son. It has been decades, but I learned this in my first semester of 15 hrs. of calculus at a University. After that, it got harder with Advanced Engineering Math and Abstract Algebra, which I didn't particularly like.
A derivative is the same as a slope of a non linear function. When I was a Business student at Saint Mary's University during the 1990s, I took an "Introduction to Quantitative Methods for Commerce II" course, which consisted mainly of Differential Calculus, Statistics, Sets, and Probabilities. I also had to master the four different derivative rules, Power, Chain, Product, and Quotient. However, we didn't learn about anti-derivatives or Integral Calculus, but its easy to master once you learn the fundamentals.
you're literally saving my life. SO clear. My textbook SUCKS and is SO confusing. Thanks for helping me get through my homework. You explain things clearly and are not boring. Appreciate it.
I am from India. Thanks a lot for teaching calculus in a simple manner. All Indian teachers on youtube limit their content to stuff that is asked in exams rather than teaching for knowledge.
Nancy, your math videos are good refreshers for our senior engineers, especially when dealing with complex transient problems. And several of our younger production employees are interested in engineering, and maybe pursuing engineering and your tutorials are an excellent means to motivate them. Thank you.
Thank you Nancy. I am taking your videos as a reference each time when doing math with my daughters and they have both became good at it. The school marks are also confirming that. I appreciate your work and your commitment. Thank you.
Very few people explain concepts in an understandable way. I mean, when you ACTUALLY UNDERSTAND what it is and why it is there. It's easy to just DO IT because you saw 100 other examples but, what it really is, is what matter the most. This was amazing.
This video was recommended to me.... and although I'm no longer in my calculus II course, I become a bit nostalgic of the times I would stay up late watching your videos to solve just a few questions... ah good times! Thanks for your help during many countless efforts at my homework and exam preps!
God bless this lady. I’m so glad I tumbled upon this page my calculus teacher at the university explains things in the most complicated way possible , even if you understand you’ll end up confused. But THIS HERE IS GOLD!!thank you you soooo much❤
That was incredibly helpful, I just had my first lectures on derivatives a couple days ago, and this part was breezed over as if it were assumed knowledge. Thank you for breaking it down.
Hey there, I completed my engineering an year ago... and just on this random day I remembered how this channel helped me out in my first year. Thanks a lot! Lots of love, stay safe and healthy. I'll never forget you. Thank you. ❤
You are awesome! I have been trying to understand this for at least 2 weeks now. My teacher doesn't explain things as clearly as you do. Keep up the good work!
I took calculus years ago. If my teacher had been this good at explaining it, I would have done much better. Now I actually do watch calculus videos just for fun. This was a great reminder of where the derivative rules come from.
Wonderfully clear. I have not done math for decades and your explanation provided clarity like never before. I will have to re-view your video. However, I do not quite understand what a limit is or its purpose. Again, thank you again for being a wonderful instructor. You validated my suspicion. I always suspected that math could be taught better.
Derivatives are all about rates of change. One thing is changing with respect to something else. Let's say the economy is growing with time. You see on the news that it grew 1.2% in the last year. But then you read that it only grew 0.2% in the last quarter. And, in fact, it shrank by 0.1% in the last month. Clearly it grows at different rates over different time periods. If I'm interested in the current trajectory I might look at what it did in the last week, or the last day, or even the last second. (I know that's kinda hard to do with the economy, but it's just an example). As my time interval gets shorter and shorter I get closer and closer to the _instantaneous_ rate of change, otherwise known as the derivative. You might argue that there's no such thing as an instantaneous rate, but I will argue back that I can get arbitrarily close. That's where limits come in. They let us talk about arbitrarily small things (or large things -- but for differential calculus it's always small things). Our notation for an arbitrarily small -- or infinitesimal -- quantity of time is dt. If E is the size of the economy then its derivative, or instantaneous rate of change with time, is dE/dt. It is "the limit" of the rate of change in the size of the economy as the time interval we are talking about gets arbitrarily close to zero. What use is this, other than a fancy notation? Well, the world is about nothing if not change, and derivatives crop up literally everywhere in the physical sciences as well as economics and other social sciences. Using the technique that Nancy demo'ed, plus some handy shortcuts, we can deduce a lot of useful stuff. (P.S. I went back to school after decades away from maths too, and got an advanced degree in astrophysics. Never too late).
What a great teacher! I had a submarine captain from WWII for Algebra, and for more advanced math at a prep school, old books by a retired math old bat. I learned everything on Math by buying books and learning it myself. I have a ton of Calculus books of all sorts, but something I learn more from videos such as this. Also the instructor is very pleasing to the eye, and she certainly can draw the equations very quickly. (yes, I know).
@Julita Aishah I mean, if you see that a math video has more than 300k views and 90% of the thumbs are thumbs up, you can deduce the tutor explains things well. I would still watch it if I'm interested in the subject(like in this case). Sorry but you've lost this one, you girl
I want to thank you. Your videos helped me passed my college math courses with either As or Bs. You explained the concepts in a much more clear way than many of my professors. Thank you b
I'm Kingsley from Ghana, I have not done Further Mathematics (known as Elective Maths in our Country) before.

You're so amazing please keep posting videos back again, your explanations are an absolute masterpiece, I have never seen someone explains calculus that perfect !
Thank you for not talking in a super academic manner like literally everyone else. It helps while learning complicated topics to not have the instructor talk to me like the topic is elementary and if I dont understand then I'm stupid....
Thank you Nancy. Literally, I've been to tutoring, watched Chegg videos, other TH-cam math videos, but yours is by far the most explanatory and I really get you. I like the fact that you dont try to make it hard and confusing as well as being open to new methods and easier ways for different learners. You amazing and beautiful too :)

7:47 = magically illuminating! And, the demonstration for the origin of the notations of derivative is enlightening. Rare combination of beauty and intelligence.
Thanks Nancy! I learned that the derivative f'(x) is the change in the output (y) divided by the change in the input (x) as the input approaches zero. Math becomes more enjoyable once you understand the underlying concepts so thank you for sharing this joy with me!
Perhaps it depends on having just watched other videos about this topic so, little by little, I had just assimilated the concepts but, apart from this, your explanation is the clearest ever ! Thank you again!
Studying for my final! Great refresher, I used this same video when I was learning this concept earlier in the semester. Its fun seeing the concept again after learning so much!
Cant believe math actually could have been explained clearly in high school...Thank you so much for your videos.... saved me from dragging myself through the lectures...
Better: The derivative is how fast something is moving or changing. The integral is that thing that is moving or changing. The remote control is the derivative, and the plane is the integral. The steering wheel is the derivative, and the car is the integral. How fast you're walking is the derivative, and how far you've gone is the integral. There can be derivatives of derivatives or integrals of integrals, but that can be in another explanation. It really doesn't need to be a 14-minute video.

I love your videos. You're able to explain things so effectively. I swear, my professor wasn't able to convey as much info to me throughout an entire semester of precalculus and he earned three math degrees in grad school.
Everyone should watch this video. You did an exceptional job of explaining the definition and the thinking 🤔 behind it. My Calculus Prof in college gave a similar but more basic explanation. This is a complete explanation.
I am currently studying machine learning however I never went to college so my primary source of study is basically TH-cam lol. Anywho, I found this to be extremely helpful in understanding the back propagation algorithms in a neural network! I look forward to more of your videos as my learning progresses! :)
I'm just about to retire, having received my EE many years ago. This presentation is very good. It is worth noting that the initial equation for the limit had 'h' in the denominator, so a solution at zero was undefined. After the limit algebra is completed, 'h' is then sensible for zero, and the equation becomes solvable.
You explained this way better than any of my math profs did. Its been 15 years since I took calculus and I knew the rules to get the first and second derivative, but I didn't know the underlying theory. Thanks.
It's great to see someone thinking through what they are explaining. The sign of a natural teacher.
It takes true mastery of a subject to make it as simple as you do. Super grateful! Thank you!
