Calculus - Lesson 9 | When does the Derivative Not Exist? | Don't Memorise

[@InfinityLearn_NEET]

The general and most important application of derivative is to find the Rate of Change of a Quantity. For example, to check the rate of change of the volume of a cube with respect to its decreasing sides, we can use the derivative form as dy/dx. Where dy represents the rate of change of volume of cube and dx represents the change of sides cube.

This is most heinous crimes against math and reality why are you be fooling at zero point you have flawed Logic basically calculus is satanist agenda and hiding the truth and you are in friendship with this evil 😂😂😂😂

[@ajaychopra9509]

you are doing great great job.... i should say great for humanity....students jam their brains studying formulas again and again just to solve problems without knowing the physical significance of these important topics... you are making mathematics visual

[@Njs1211]

For vertical line it's undefined because division by zero is undefined For horizontal it's zero. 👌

[@abhishekpawar4213]

Correct

[@fortfanop]

Yeah imagine trying to drive a car up a vertical wall, not possible right?

[@texasdrz9515]

@The Technological Electronic Guy Challenge accepted.

[@sneha10010]

​@@fortfanopno, It's possible for batman

[@devooko]

@@fortfanop It is possible if you have a car that can perpendicularly climb, and can overcome gravity

[@VibingMath]

This video should be used as standard math limit class demostration, great work!

[@abhik294]

Thanks!

[@rudrarunim3333]

I'm from humanities stream, but I wanted to understand calculus and for sure it told me the way to hold on to this bizarre but but beautiful aspect of mathematics. Calculus is the language of practical mathematical problems. I heartily thank for your contribution. 💫🍃

[@VishnuSharma-wu6mw]

I worked the whole year of my 12th to understand calculus and was updating my knowledge about the same in the following years but finally learned this concept of derivative from you, have no works to thank you

[@jyothikj6434]

This channel is god sent . It name itself makes me to not memorise . Understanding concept is very effective

[@InfinityLearn_NEET]

Thank you so much Jyothi for your appreciation. We are glad that you understood the concept. For more videos, please visit our website - dontmemorise.com/

[@amranmohamed377]

A vertical line doesn't have a slope because it doesn't have an x-value. Slope tells us how y changes when x changes, but with a vertical line, there is no change in x, so we can't determine how y changes. Therefore, the slope of a vertical line is undefined.

[@Dineshkumar-gd1fp]

This was asked in my business mathematics public exam 5 marks question l did it correctly

[@srinivasanarayanan1128]

Slope of a vertical line is undefined because its angle of inclination is 90°

[@syamalchattopadhyay2893]

Clarity in this video is outstanding.

[@sadiqsyed8803]

For vertical line, Change in x=0, Change in y =R(any real number) Hence,for same change in x,there are different possible changes in y(undefined change) Therefore,It's slope is undefined But,as the horizontal line tends to be a vertical line(rotates),its slope approaches infinity.

[@pavanavula9025]

Slope of vertical line=slope of y-axis Angle by y-axis =90 degrees So Tan 90 is undefined

You deserves a millions subscribers

[@kirantoal8944]

Congratulations 🎉 your subscriptions are increasing

[@InfinityLearn_NEET]

Thank you so much, Kiran! That's possible only because of such amazing learners like you. We are really greatful and pleased by the response we recieve from all of you. Keep watching and supporting!! 🙏😀

[@jainvansh2006]

5:34 we can approxiamate the rate of change to the tangent at that point because as we continue to maginify the point ,the graph increases to resemble a tangent at that point.

[@abhik294]

Amazing explanation 👍

[@sachinkataria8867]

You are doing such a great job. I love your channel so much. Thank you for all these amazing videos..

[@daksharora642]

The slope of the Vertical must be Undefined/Infinite because when we divide it the denominator is zero And also thank you for making these videos. I am currently studying in class 11th and in Physics third chapter there is use of some derivatives. There was not much written about it there so I searched it out of curiosity and yours is the only one which made me understand :D

[@gauravnegi4312]

Yes, in 11th there is chapter derivative in maths, but it is taught way after when derivative are used in physics. IT had troubled me a lot too.

[@usama57926]

great explanation

[@sayedmustafa6587]

Great work .. please can you make videos about differential equations !

This is so well made

[@curiousminds1029]

slope of vertical line as it is perpendicular to y-axis, is equal to infinity or it is undefined. as there would not be a run or (X2 --- X1).

[@anandangkr9853]

Tq very much sister....👏👍💟 You are ultra Legend 😉

[@goddatinomya9313]

Thank you You gave best explanation Slope of vertical line is infinity

[@TheEarlyAstrotype1024]

What's the slope of a vertical line? I don't really know if it is infinity or undefined.

[@japhatkorowa]

Madame your explanation is very outstanding, I like your explanation and kinds of inormation you presented🎁. Madame thanks for your teaching.

[@hamzanasir1590]

Your explanations are very precise Mam. Keep it up 👍👍👍

[@InfinityLearn_NEET]

Thank you so much Hamza for your appreciation. We are glad that you understood the concept. You motivate us to do better. Keep watching our videos : )

[@lokeshkapgate6088]

what is mean by inverse of trigonometric ratio and what they equal to

[@sankararaokalaga]

5:39 5:39 5:39 5:39 5:39 5:39 5:39 awesome

[@soufianeyes4278]

I think the slope of a vertical line =y/0 So it is undefined (because deviding by zero is undefined)

[@santosh9909]

Your videos are very nice and useful. In short, clear cut to the senses. May I request you something...? Please try to finish a topic completely in a subject and then upload another video of another subject cause there's much gap in uploading between 2 consecutive videos of the same topic. Eg : complete the topic of differentiation first and then go to biology, but not to make us wait much plzzz. I'm much interested in integrations now, awaiting for the continuation of the revolving of the surfaces in the previous video. Plz try to upload it soon. Thank you 😊

[@r.malleshpeddapalli3151]

Slope is tan A for a being inclination. And we know the inclination is 90° and tan 90 is not defined

[@AlessandroZir]

thank you so much!! very nice explanation; just love ur channel! ❤️❤️

[@StudentWalaGamer]

Nice👍

[@ৰিংকুভট্টাচাৰ্য]

Thanks

Great.. i was designing cnc machine motion positions... Stuck some were for polygon interpolation so went through this this things

[@sunflowerboi]

The slope of a vertical line does not exist because infinty/infinity is undefined.

[@pritigajjar4105]

Slope of a line can be computed by finding the tangent of the angle the line makes with +ve x-axis in case of vertical line it makes 90° with the x-axis so its slope is tan90° which is undefined

[@zorak0044]

40. If the two functions f and g are differentiable at the number x1, is the composite function fºg necessarily differentiable at x1? If your answer is yes, prove it. If your answer is no, give a counterexample. please help!

[@lanadelray9169]

If you get 0/0 for the derivative what is meant by the slope ? I mean if d/dx =0/0 what does that tell about the slope of the point?

[@venkatasriharsha5911]

slope of vertical line= not defined because we measure slope of a line with respect to the angle with X axis so, by trigonometric ratio tan, we get tan 90 which is not defined or infinity

[@vikasrai4]

at 3:23 how f(0-h) = -(0-h) ? Can some one please explain this! I'm so confused.

[@khushabu_]

8:40 Slope = ∞

[@chkvid01]

My question if delta x = h then f(h) would be different from simple delta x because in the first case we are solving some equation f(h). So if we give some value to h (or delta x) then f(h) is not equal to h unless f(x) = x. in that case delta x = delta x or in other words h = h

[@ayasguitar8718]

Vertical line eq:x=0 the slope then is equal to y/x=0/0 undifined form

[@kvnagendra5354]

This was osm

Glad you liked it! Happy Learning. :)

[@antoniusdaivap7759]

Whats an osm?

[@abhishekpawar4213]

Slope of line parallel to y axis or a vertical line has undefined slope😎😀

[@rouchellemcfarlane4178]

Must we always calculate x>0 and x

[@mandeepkularia]

Slope of a vertical line equals to= not defined or we can say it does not exist ❤️

[@sparshraul4671]

There is no slope of a vertical line because a vertical itself acts like a slope. It just coinsides

[@maheswari653]

Tq so much .....

[@vedhanthg1811]

Well, in basic terms it is undefined, but after using limit concept it is infinite as anything/0 → ∞

[@بوفارسبونورا-ص7ه]

A slop of virtical line = infinity

[@7thclasstopper952]

We know that slope means Y/x So If 1)verticle then x=0 So =undefined 2). Horizontal then y=0 So =0

[@jaswanthduppalapudi923]

Please upload vector calculus vedios

[@RoyalYoutube_PRO]

infinite or undefined

[@debabratahira6578]

Slope of a vertical line is 90 degree.

[@nikunjlotiya3099]

Great

[@jansykj8684]

Slope of a vertical Line is tan90 ie = not defined

[@ayushjadhav5981]

slope of the horizontal line is undefined because here angle of slope will 90 degree tan90=undefined thus slope of straight line is undefined

[@archanadash2605]

if y = |x| then for any value of x , the value of y will be +ve for any value of x. Then how are we defining y = -x for x

[@sandhyapol937]

Since it's ratio of slope will be 0/0 which will be undefined

[@subashrao4532]

Slope if vertical lines x=y=0

[@التوحيد_اصل_كل_خير]

The slope equal infinite number

[@mohammadbenrebia1078]

Love it 💖

[@dakshyinib2867]

Yes

[@ratha_bhabatosh]

So, does this mean that there's no differential equations for |x| , x⅔ & x⅓ ?? 🤔🤔🤔🤔
