The Quotient Rule has been deeply puzzling me most of my life, haunting my dreams, affecting all my relationships, prevented me from flying or parachuting and I was absolutely petrified of ants. Now, I'm cured!!! Thank you! Thank you!
I'm a dumbass. The only way I remember it is to use the product and chain rule with the quotient written as a products written to the negative 1 power. So instead of f(x)/g(x) you get f(x)*g(x)^-1. Then using product and chain rule f'(x)*g(x)^-1-f(x)*g(x)^-2*g'(x).
I learned it almost the same but just a little different " Lo De Hi - Hi De Lo, Over whats squared below." It rhymes a little more so it might help you remember it a little more.
this did help a lot. the teacher just threw product rules at us and i didnt even realize i needed to know the quotient rule for fracions. your method to remember them easier helped a ton too. thank you so much!!
Excellent Series Nancy - You are the best maths teacher in RUclips. Will you please do a series of lectures in 1) Permutations and Combinations 2) Statistics basics and Probability Thanks
@NancyPi thank u for the awesome vids they helped me with my school work alot. U are alot better than my math teacher 👍thank u and keep up the great work!!!:)
Nancy is one of the cutest math teachers on youtube these short and concise videos help me soo much . started watching her in 11th grade now i am first year engg and man i still watch these vids.
Im so so happy that a classmate told me bout you! Granted it was hearing boy talk and then how you explain things to an understanding level that anyone can understand. Thank you thank you
wait a minute..... WHAT?! I've been trying to understand the first way you showed and then you show me the easier way..... 🤯 Why is my professor NOT using your videos?!🤦♀
Thank you for these videos! The quotient rhyme is almost the same as my teacher taught us but instead of "Lo * Lo", he said " Square the bottom and off we go!" It rhymes well with "High dee low". Might help somebody else to remember these rules!
Thanks for the calculus video it really really helps especially when your explanations are easy to understand compare to my professors. Thank you for your video and I hope you continue making calculus videos because they really really do help a lot
I never remember the quotient rule. I simple use product and chain rule to re-derive it. This is what you must do if you have two functions f,g: R^n\to R^m, because "division" no longer makes sense. Instead, you multiply by the inverse matrix. Also, since derivatives are matrices (linear transformations) in higher dimensions, multiplication is not commutative, and the quotient rule will not resemble the one dimensional quotient rule.
She is presenting the things in best way, can someone explain to me how she is writing. I dont understand, she is using a glass board but how it works. Excellent work as math teacher.
The way I learnt the quotient rule was to do heaps of examples until it became 2nd nature.So it is no big secret ,I found the Khan Academy the best place to practice.
Hey Nancy, I know you did a video on Inverse function already but I’m taking pre-calc now and I have a inverse function problem to solve which includes Natural Logarithm. If you have time, would you please explain that in a video? Thank you very much :)
I derived the quotient rule by considering the function "1/LO", then using the product rule of HI and 1/LO with chain rule. It might not be quicker, but you won't make a mistake if you know your products and chains. P.S. in my region the quotient is taught d[u/v]/dx = (vu'-uv')/v², and it actually rolls right off the tongue! "vee dee yuu, minus yuu dee vee, all over vee squared."
@@mountainc1027 In Romania, the Quotient Rule is written in the math manuals a bit different, d[u/v]/dx = (u'v-v'u)/v², in the products the derivative comes first. With no indication whatsoever about how to "sing" the formula :-)
As a math major I really don't believe in the Hi Lo J-lo rhyme. It making matters worse. It's just more formula to remember. You should just remember the quotient rule which isn't that difficult and it should become natural to you.

best comment ever😂😂😂😂😂😂. affecting all your relationships🤣
what about integration by parts
Lol
Dude, wtf 😂😂
I don't understand how people dislike her videos even once, she literally is the reason I passed so all my math courses. Let's go NancyPi
Daniel Thompson subscribe me
They're proof that there's pure evil in this world.
It's coz everything is backwards😬I'm confused
47 dislikes out of 3700 is not many people.
@@TheBlackLodger Exactly
I remember: "LoDhi, HiDlo, bottom squared good to go"
That's fine, as long as you remember that you have subtract High D-Low from Low D-High.
I learned it almost the same but just a little different " Lo De Hi - Hi De Lo, Over whats squared below." It rhymes a little more so it might help you remember it a little more.
Mine was "Lo De Hi - Hi De Lo, square the bottom and away we go!"
Professor Leonard uses the same rhyme
Bruuuuuuhhhh!!! This is sooo much better! College professor literally complicate this rule for no reason 🤦♂️ Thank You so much 😊
You are the wisest and calmest of all math sages, thank you for your time.
I've never watched your videos but NancyPi and google said 3:14 run time and "Made Easier." Ok, you deserve the watch!
Thank you very much Nancy, I was struggling for 20 minutes, but after watching your video, I understand in 2 minutes, Thank you

"Low D High over High D Low, square the bottom and there you go" *applause* thank you, thank you

Simp
This brings back memories of calculus 25 years ago
NancyPi’s videos are proof that sometimes people accidentally click on dislike when they meant like. There can be no other expiation.
Im so so happy that a classmate told me bout you! Granted it was hearing boy talk and then how you explain things to an understanding level that anyone can understand.
Thank you thank you
imagine you're a teacher in an exam room and you just hear a kid mumbling to himself:
"lo dee hi minus hi dee lo over lo times lo"
🤣🤣🤣🤣🤣🤣
wait a minute..... WHAT?! I've been trying to understand the first way you showed and then you show me the easier way..... 🤯
Why is my professor NOT using your videos?!🤦♀
An extraordinarily fun way of remembering the Quotient Rule. Kudos to NancyPi.
i can like littrally bing watch all your videos, i get doses of dopamine from these videos
Thank you for these videos! The quotient rhyme is almost the same as my teacher taught us but instead of "Lo * Lo", he said " Square the bottom and off we go!" It rhymes well with "High dee low". Might help somebody else to remember these rules!
You make learning fun, wish you had the videos I need.
Thank you so much! I missed my lecture about this and was super confused about the "lowdeehigh" thing people were talking about
Thanks for the calculus video it really really helps especially when your explanations are easy to understand compare to my professors. Thank you for your video and I hope you continue making calculus videos because they really really do help a lot
Idk HOW i missed this video before but thanks for this! 🤗💕
Do u support blm
Here is your fan from Hong Kong. You help me a lot in calculus.
You are a worker of miraculous transformation.
You transformed my mind.
Thank you so much. Just what I need.
Thank you watched the lecture like 3 times, didn't understood it, but 3 min into the video I remember it.
Love you! I hope you will add some videos about integrates and complex numbers soon👌🏼☺️
Her mirrored writing skills are seriously respectable
Doesn't she flip the video?
@@mrnobrightside5047 you are very right
Thanks now I learned to deriviate a function like a piece of cake.
Keep teaching and am in love with your formulas madam Nancy 🇿🇲🇿🇲🇿🇲
Thank you! You're so good at explaining things.
Thank you very much for the helpful content you create and post, Nancy. Your videos are tremendously helpful for me!
This video is 3:14 long. But also very helpful. Thank you.
it's actually 3:13. but also very helpful. Thank you.
Orion McGann 3:14 to me
Well what can you say 😊 it’s NancyPi
i am from india and preparing for one of the worlds most tougheset eam that is jee , thanx nancy mam for your teaching
I'm going to write my semester test 2 just now and trust me I now understand!! Lool just in few minutes!!
Thank you Nancy this was very helpful I really appreciate your work
Thanks, Nancy, our lectures are awesome!
Oh my gosh ma’am- I love you and your videos so much!! Continue to do a wonderful job 💕💕💕
Nancy could have changed my whole school experience if I only had her decades ago!!!
Wow, this is great! Thanks Nancy. I keep forgetting the [g(x)]^2
please create an easier version of the product rule :)) this made every problem easier for me!
Andrew you can use u’v+uv’. u and v are the original functions and then u’ and v’ are their derivatives.
thanks!
yo can we get nancypi merch pls nancypi pls give us merch

I can 3D print stuff for you but idk what would represent her in the form of merch.
of my god your lessons are really helpful.
I have never really had a problem with math until calculus man. This stuff gets tough
Love from India. Mam ur teaching methid is very easy and understandable
Holy crap thank you so much I had no idea that “dee” was derivative.... I guess that’s what happens when you don’t pay attention in class
Thank you for this video! Bouta watch all the rest brb
Pretty good strategy here. That makes sense ..
She is presenting the things in best way, can someone explain to me how she is writing. I dont understand, she is using a glass board but how it works. Excellent work as math teacher.
Thank you soo much , your videos are helping me for my Msc
This is a great refresher for tutoring. Cheers!

Nancy I love you!!!!!!!! Thank you!!!!!!!!! made remembering this so much easier. You're awesome!!!!!!!
Thank you again ma'am Nancy
thank you so much 🙏 this helped so much
Thank you soooo much u saved my time!
Thank you Nancy!
Thanks Nancy - I DO like math - and I DO like your videos!
Thank you Nancy ❤
Amazing!! Thank you so much for the help.

Thank you Nancy
Nancy you the best❤️ wish u were my teacher in real life❤️ Thanks alot❤️❤️
nancypi you are a queen!
hello thanks nancy
Goated for this one
Thank you so much ! I’m studying for my exam tomorrow and I’m freaking out lol
Thank you NP
Beautiful inside and out!
whats ur skincareee?? u are glowinggg
Thank you so much!!
Brilliant teacher!
Great teaching as ever. Thanks.
Thanks so much!
This is awesome thank you.
Thanks alot Nancy!!
thank you so much you are explain in very easy way i understand the derivative very well ^_^
Nancy if u were my professor I would pay attention and show up 2 class everyday
Thank you
The 26 dislikes are from the math teachers who want us to suffer.
This method is really catchy but I was able to use it and come up with my own method
which is?
I derived the quotient rule by considering the function "1/LO", then using the product rule of HI and 1/LO with chain rule.
It might not be quicker, but you won't make a mistake if you know your products and chains.
P.S. in my region the quotient is taught d[u/v]/dx = (vu'-uv')/v², and it actually rolls right off the tongue! "vee dee yuu, minus yuu dee vee, all over vee squared."
or: vee yuu prime minus yuu vee prime over vee squared

Hi Nancy, could you take a video about derivative of inverse function?
absolute legend
Splendid
Awesome👍👍
Hey Nancy! Could you plz do a video on how to find derivatives on a graph from function? Thanks
easy just find the slope at the point
ur the best. thank u

AWESOME STUFF
Loveeeee it!!!
Good video
Can you please cover Calculus: Higher Order? And with examples using radicals?
@NancyPi Can you do a video explaining instances of the Product Rule and Quotient Rule being used in the same problem?
Can you explain how you write backwards so flippin easily? Thank you.
But what if I cant yodle?
OMG it’s very useful.
