Thank you Nancy for sharing your knowledge with your viewers. I could not understand this for 5 months and now I understood due to watching 1 of your videos! You explained diligently, and you gave your all so thank you and God bless you abundantly for simply giving.

Better yet, set u^2 to (1-x^4) and you'll eliminate the radical altogether. Reference Elements of the Differential and Integral Calculus by Granville, Chapter 26 - Integration By Substitution Of A New Variable. Rationalization. The text (free PDF) is available for download at the Internet Archive.

Great mam wow🎉🎉🎉🎉

this was explained very well

She’s really pretty

you're saving my a levels

THANK YOU!!!!

OMG THANK YOU! This was so helpful!!!

marry me

omg this is great!! Thank you so much!

Students attendance would 100%

If you were math teacher in our college, all students would have cleared maths,

Looking stunning

Nancy when I was engineering student,I never liked maths , but since I started watching your videos, maths bacame my favourite subject ❤❤❤

Actually, squaring wasn't necessary for the first one; I could factor it in my head into (x + 7)(x - 1), which would give the values of x as {-7, 1}.

❤

Tank you!

oh my god Nancy I am a grade 10 student and been watching you for 1 year you are awesome and so cool and back writing abilities are bomb

i love Nancy

I ❤ u

Thanks for sharing your knowledge.appreciating your effort to make the concept clear

I want to mass with limits😂

25:20 BUT WHERE DOES THE DU GO??

Almost 9years later since i studied maths in school, this video for the 1st time in my life explained solving equations so lucidly that i can't thank you enough Nancy <3 and you proved that literally Beauty with Brains is a thing <3 thank you so much

What is the board?

wow nancy you are so beautiful🤩

Hi Nancy you helped me pass my exams Thank you 😊 ❤

Gud

Thanks NancyPi for your lecture on a fundamental understanding about the meaning of limits and therefore derivatives. Gracias desde Uhland, Texas. Una bendicion y abrazos donde sea que se encuentre. Hasta pronto!!

Thank you 💞

Thanks!

thanks it really helped

i may be sounding weird but for a milisecond i literally thought "OLIVIA RODRIGO IS TEACHING MATH??! THE HECK?" and then realised its not liv.. sorry 😂

You are good in teaching maths but you are blushing and you are making your students to concentrate on your smiles than the math lessons.

Beautiful content i learned so much

Best teacher has ever seen on RU-vid..... you are the best NancyPi😢

Some niggas got excited by seeing the thumbnail

thank you

Example of beauty with brain

What is she writing on?

How where u able to set this teaching environment are you writing on a glass board and how did you set up the camera???

What I have to do to marry u 😶💗

Your voice is really calming and soft. Thanks a lot for the video.

Very Helpful 😁

For curious viewers, If you study the video carefully, she writes with the left hand. From her angle, the writings would be reversed which doesn't make sense unless she's an expert in writing mirror inverted images. So in reality, she actually writes on the glass with the right hand, but for us to see the writings in the right order, the whole image is flipped making it look like she writes with her left hand.

Best calculus teacher ever!

This is COMPLETELY FALSE. You can factor any quadratic. She's trying to FOOL you all. This method works with any quadratic : Set the quadratic equal to zero, find its two roots ( either by the *quadratic formula* or *completing the square* ), say *α & β* , then write the *Quadratic = (x-α)(x-β)* . There you go, it is factored! This works for the *factor theorem* : If *d* is a root of f(x), then *x-d* is a *factor* of f(x). I'm greatly surprised seeing none caught hold of Nancy's deception. Your looks and charisma can't fool me, Nancy 😆

We know by the derivative rule that, d/dx [ f(x) * g(x)] = d/dx (f(x)) * g(x) + d/dx(g(x)) * f(x) let u=f(x) du = f ' (x) let v=g(x) dv = g'(x). dx d/dx [ u * v ] = du * v + dv * u Take integral of both sides: u * v = intSign(du * v ) + intSign(dv*u)

Stop looking at me like that 😅
