Directional Derivatives and the Gradient

[husamalardah]

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

[rockyshepheard]

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

[amicablefire]

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 YouTube.

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!

[Deepak-pixx]

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

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?

[asgharabbas]

one of the best visualization on this topic

[spdas]

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 .

[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.

[mohsinshawkat]

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

[mahdiamrollahi]

Great, i have never heard of this term.

[kannancr]

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

[sripad]

Wonderful explanation of geometric meaning of directional derivative.

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

[muhammadasghar]

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

[yadpreetcheema]

perfect explanation, you deserve a lot more subs

[AforismWorld]

Really fantastic explanation, thank you.

[jeemaths]

Thank you so much sir, great explanation...
