- In this Physics video lecture in Hindi we talked about directional derivative and gradient of a scalar function. Gradient of a scalar field is a vector function. Gradient of a scalar function gives us the direction in which the rate of change of the value (or, more technically speaking, the slope ) of that scalar function is maximum. Directional derivative of a scalar field tells us the rate of change in the value of the function in a certain direction. To understand the physical meaning of "gradient" I give you an example - Suppose you are climbing a hill, which (the hill ) can be expressed as the function of coordinate values. You are at a certain point. You move in different directions and your assent is different. The direction in which you should move (technically correct? no.) for which you assent is maximum gives you the direction of the gradient of the function (the mathematical expression of the hill) at that point, which you are on. To understand the meaning of gradient at first you have to understand the meaning of directional derivative and for that you should know the meaning of ordinary derivative, which I think you are familiar with very well. Whatsoever we discussed a little bit about ordinary derivative also in this video lecture.
In this series of video tutorials in Hindi we are going to cover very important topics on "Mathematical methods in Physics" like, Gradient of a scalar field, divergence of a vector field, curl of a vector field and so on.
This is an indispensable topic in B.Sc. and it is the foundation of most of the branches in Physics.

I searched entire TH-cam to understand the actual meaning of divergence, curl n gradient but I couldn't find it unless I discovered this video. Thanks sir! Great content.
Pp
I fully agree with you dear
Yes I also because there are very less content of eng. Physics or bsc physics on u tube this channel is best ❤❤
@@vaibhavchaudhary9912hiii I also in bsc ist year I want to talk you???
I'm extremely happy i discovered this channel! I've been looking for such content since long time.
Sorry for nitpicking, but boys/men use "ore wa" but girls use "watashi wa" or "atashi wa". Sometimes, elders also use "watashi wa"
at 23.40 ,Sir ne ek expression likha [d(phi)/ds =d(phi)/dx. dx/ds+.....]
agar isme hum dx ko dx se Kate aur dy ko dy se Kate to
d(phi)/ds =2*d(phi)/ds , bachega bro please explain, thanks a lot in advance.
Yyes..me2
have u got the answer or shall I try as it "'s been 3 years
Watching you from Karachi Pakistan, one of the best teacher on TH-cam, watching you from of my 11th, now because of you I am in the top Engineering College of my state.
Jazak Allah
Thank you
Kya batt he sir, aesi explanation to koi ache college me teachers bhi nahi dete aur aap free me de rhe he? Mera Naman savikar kare.
Bilkul sahi baat h
Mayank Mishra at 23.40 ,Sir ne ek expression likha [d(phi)/ds =d(phi)/dx. dx/ds+.....]
agar isme hum dx ko dx se Kate aur dy ko dy se Kate to

Deepa Pandey differentiation me aise kaatna allowed nhi h... Aur jo LHS me d(phi)/ds h aur Jo RHS me d(phi) h wo dono alag h... Ek LHS waala differentiation of phi hai... Aur RHS waala saayad dell h.... Waise dono differentiation hi hota h...
@@deepapandey822 are wo {del(phi)/del(x).dx/ds} hai
del(x) aur d(x) ko kata nhi ja sakta
@@durgeshsharma2734 right del X aur dx different he aur hum yeha chain rule apply nehi Kar sakte!!!!del X MATLAB X Ka partial derivative y KO constant man k aur dx to ordinary derivative show karta he jb y variable he!!!
Sir, mene aap jese teacher sirf youtube per he dekhe h. But still I am blessed to get education from you. Keep updating.
GREAT SIR .
I'm a B.Tech student in IIT Ropar and I saw your video for my MA101 Calculus course. You are the proud Hindi medium teachers.
Jitendra bhai,
It is matter of pride for me.
IIT ians are watching.......
Sir 19:19 second pe video me ek darawni awaz hai
Mai to dar gyi
Suniye ek baar #19:19

Oh my god !
So heavyweight compliment !
Thank you for your support.
God bless you.
Sir, aap nhi jante ki apne mera kitna bda doubt clear kiya he. I just want to salute u sir..
Apne mughe chinta mukt kr diya.
Agar sabhi teachers apke jase hote to hr ek bachcha genius hota.
Wow, I almost understand Hindi!
Great explanation. I watched every other video but they would just start with formula directly.
Not even completed 2 minutes in this video & i knew i had to subscribe this channel!!👊
I had completed masters in electrical engineering... Up to now my concepts regarding gradient and divergence were never crystal clear. Thank you very much sir. This is the best explanation video about vector gradient in this earth
For better understanding of Gradient

sir ap mahan ho itne gradient pe videos dekhe... but ye apki video subse jada satisfaction diya. ap jese teacher aur mile ❤ dhayn ho sir ji ap
This is a gem!!. Even better than reading big books in calculus .
In this era student and teachers always try to solve the questions
But you always create concept.
Thanku so much.
Sir behetareen video.. jaadu hai apki videos mei.. itni clearity se koi nahi samjhaya aaj tak.
Meri life aap jaise teacher and TH-camr k Bina kuch aur hi hoti...it a beautiful topics ko Mai skip Kar deta ........God bless you sir bhagvan aapko Jo chahiye vo sab Dede 🙏🙏🙏
Such clear explanations!!! Very easy to grasp when you teach. You really are awesome sir!!!. Thank you so much I understood this concept very soon . Please continue what you do !!!
He is simply a genius and a lucky man as God has blessed him with so much knowledge about science.
Sir u explain your each and every statement .....u r wonderful sir!!...... ..plz keep uploading sir we need u!!..

i didnt know how the total derrivative of a multivariale function had come... But after watching this video ive understood and tasted the happiness of calculus ...... Great thanks to EduPoint .. Wish this type of video will come more and more
You are one of those few who knows their trade ins and outs and more importantly adore it. You have that awesome talent to make a layman like me to understand something quite complicated otherwise. My humble request is to take up topics hard to understand such as quantum mechanics and general theory of relativity as your future goal. I
know you are one helluva of a person who can do it and believe me this endeavour óf yours will bring heavenly satisfaction to you in its wake as well. I know you know more than you teach....and thank you.
Hello Rajat Ji,
Thank you for your encouraging words.
I have been trying to understand Q.M. for last few months. But, frankly speaking, I am not reaching the minimum level a teacher should have. And you are absolutely correct that Q.M. and G.R. will give a physics student or teacher the ultimate fulfilment.
I am trying. From the bottom of my heart, I am saying that I am trying.
EduPoint Not only an incredibly fine teacher with so vast understanding of the subject but a downright honest person as well, that is who you are. I begin to like your persona just as much I like your videos.
Dear Rajat Ji,
Once again thanks for your loving words.
Let me tell you one thing, beauty lies in the eyes of beholder.
Best video in hindi with topic depth 👏👏👏👏nice sir ji lage raho ..., engineering grafics pe banao sir.
Very very very nicely explained...I suddenly found this channel while searching for practical explanation of gradient.....by the way thanks
Curl and gradient, vector and scaler field ke bare me kafi saare video dekhe
Lekin I sure, ke aapke video se aaj samaj aaya ki ye quantity kya hoti hai,
Thank u sir,
take a bow , I must say you have god gifted quality of how to teach a concept, thank you very much , these are invaluable content.
Ever the best lecture on directional derivative. 👍👍👍
😮 सर आप जैसा पढ़ाने वाला bsc के लिए शायद ही कोई होगा 👍 बहुत अच्छी तरह से समझा दिया।
This is what we called quality content 😭❤
I am learning Machine learning. This helped me a lot. I have no words to express how thankful i am. Everywhere i am finding 2d explanation only mostly but this is best the explanation using 3d example.
Sir, kinly upload more such doubt clearing videos . Nobody could rexplin the ideo of direction of gradient and related path with such diagram . Pranam sir, from West Bengal 🙏🙏🙏
Guruji aap jaise spiritual + scientific soul ko koti koti pranam.. 🙏🌹🌺🌼🌸💐🥀🌷🌹🌺🌼💐🥀🌷💯💯🕉️🕉️
Better than any lecture I heard about gradient field

outstanding sir....this is the mathematics..
Awesome explanation sir Hats off to u
Engineering होने वाली है
पर ये बुनियादी बाते आजतक किसिने नही बताई
शायद इसलीये की अधिकतर को ये मालूम नही
और जिनको मालूम हैं उनको इस दौडभरे जीवन मे समझाने से ज्यादा सिखाना ही ठीक लगता है
धन्यवाद आपका
Aaj hame pata chala ki differential actually hota kya hai aur eska use kya hai abhi tak to mujhe ye bakwas lagta tha ki dy/dx karane se kya hota kyu bekar ka dimag kharab karana lakin aaj malum hua ki math bhi physics ki tarah real life se judi hai
Thank you so much sir aap jasie teacher ho to kuch achha karenge aap se padne wale students aap bilkul deeply bataye ki actually ye hota kya hai 💐👌👌👌👍
One of the great teacher on Earth
Legendary explanation best video on gradient
Only reason to impress by Indian teachers.
Love from Pakistan.
Amazing way of describe physical meaning of Gradient... Thanks sir
Aap mhanun ho sir jo free main itna achha pdate h
Wow amazing sir ,,your vocal is loud and clear thanks

Thank you very much for support you have shown.
Bas aap sab ki dua milti rahe.
Sir ap ye surface ke liye kar rahein he but jab only function of x y z raha tab kese prove karenge..thoda feel lao aur ek part 2 kar ke...example f=X^2YZ^3...ye functioj he..lekim grad of f ka feel kese karein
sir what a grea lecture ....plz provide pdf bcz its too hard for me to make note on this although i understood all the minimal to minimal points of this lecture
Learnt this topic first time in real.
Thank You Sir.
You guys are the real hero,great help....

Good evening sir. Well explained. Thank you sir.
Sir it is too good video.Make one video about delayed choice quantum eraser experiment
sir good work but bsc, msc, physic, math Ki sari books ki video lecture upload kerain I really need
Hello Kamran Khan !
Thank you for your encouragement. Yes I am uploading. Be with us.
And as always ... thanks for watching.
example se samjhane ka method zabardast hai
Sir, your videos are excellent.
How we can find "normal vector" to the "surface" by another method... Without "direct" using of gradient
harshit gupta look for khan academy's video on this topic
Genius. Awesome Lecture. Keep it up👍
Aap jese teacher Hindi ko fir se mahaan bana sakte hein.
Very well explained sir. Thank you so much ❤
Awesome👏✊👍...
Sir pls make videos on double integral and tripple integral
Ur explanation is superb
