Directional Derivatives and the Gradient

[@husamalardah890]

YOOOOOOOO SHITTTTTT after days of trying to understand this and watching countless of useless vids I came across this wonderful vid. This man deserves recognition

[@guitarttimman]

Uh yeah but he still doesn't understand what it truly means.

[@rockyshepheard6054]

This is the simplest and best visualization of DD I have ever seen. Great job indeed!

[@amicablefire9693]

This is the best explanation I have ever seen of this topic. Short and explained so well.

[@YouUndeground]

Thank you! The geo explanation was the best one that I found on KZbin.

[@venkateshg9450]

Graphical picturization is one what makes students understand better. I'm being a teacher I found it very good for lovers of mathematics. Thank you!!

[@RoylanMartinez]

I have watched like 6 videos and until this one I could finally understand what the f**** directional and gradient vector actually is!

[@sarvanray3971]

Same

[@Deepak-pi9xx]

Thank you very much. I saw so many videos but nobody explained meaning of Directional derivative so simply. 😇

[@spdas5942]

The best video on directional derivative . But I cannot understand the direction of gradient is updard or inward ! Kindly upload a video on gradiend with its direction and the plain on which the gradient vector is . Thanks for such a video .

[@jacobvandijk6525]

A good graph is worth more than a thousand words. Thanks! Is there a way to find the equation of the curve on the surface?

[@asgharabbas9885]

one of the best visualization on this topic

[@v.rao1]

1:53 as per logic, unit vector direction decided by the user right, my logic is if am planning to check the change in the height in a particular direction, so I can decide the direction of vector right? here i am placing the vector right for analyse the changes in a particular direction? please clear my logic

[@prathyusha5393]

Thanks for the clear pictures !

[@ChandrakantChandrakar-m3q]

Great work and simplest and easiest way and visualisation. Thanks 🙏 pranam sir ji

[@BoZhaoengineering]

Before trying to understand gradient and directional derivative , it is nice to understand and visualize vector filed first. Because gradient of a function is a vector valued function.

[@yadpreetcheema4806]

perfect explanation, you deserve a lot more subs

[@kannancr1652]

Is directional derivative concept you explained is applicable for vector valued function also...

[@manikantabandla3923]

Visualization at its best.

[@mohsinshawkat6531]

Thank you very much . Your explaination made the whole idea clear for me. Gongratulations

[@sripad72]

Wonderful explanation of geometric meaning of directional derivative.

[@mahdiamrollahi8456]

Great , i have never heard of this term.

[@muhammadasghar4944]

Wounderful sir really really thanku I understood 100% sir you are Great thanku again and again

[@AforismWorld]

Really fantastic explanation, thank you.

[@choungyoungjae8271]

awesome. How do you draw that graph? which tool was used...?

[@vanamabhinaytinku6552]

Superb concept sir

[@jee9maths]

Thank you so much sir, great explanation...

[@manjunathkotabal]

Thank you sir ,I understand this in just 5 mins for which I spent almost an our in other vedio but didn't understand

[@jee9maths]

Thank you so much sir.

[@student369]

Thank you Sir🙏

[@umaizasattar9971]

It's fantastic

[@midhunmohan8279]

You are great sir😁😁😁👏👏

[@alessiodenny6123]

outstanding !!

[@sripad72]

Nice geometrical explaination

[@siphilipe]

Good job. Thanks!

[@KuldeepSingh-wo4yl]

Well explained 👍

[@srinivasaprasanth]

Very helpful

[@saurabhmahra4084]

thank you so much

[@ashwaniagrawal5770]

Thnk you sir

[@revathikankanala3933]

Thanks allot 😊

[@sripad72]

Great

[@greengirl4985]

Why do you sound sad
