ONE OF THE BEST CALC VIDEOS EVER THANK YOU

[@Genie0007]

very fast,precise ,detailed and sooooooooo clear

[@NormanWasHere452]

GOAT. My Lecturer didn’t tell me how to do this but expected me to be able to answer these questions.

[@depanwitamaiti4350]

The best and simplest explanation 👌🏼

[@aqua1918]

best video ive watched for this topic, so easy to understand

[@jerryw5777]

This is the best video on youtube for those who needs help with Chain rule of the second-order partial derivative.

[@RenyxGhoul]

The tree diagram is a helpful and simple way of doing more than one iteration of the chain rule. Thank you for that! The final expression is also very neat.

[@neon-3467]

best out there. Also your handwriting is amazing I never seen someone willing use those variables and write them as well as you did

[@giuseppecammarata7528]

Thanks so much indeed, I had been striving to find this explanation anywhere, to no avail until now!

[@Lusana32]

You are the absolute best. So much better at clarity compared to the rest.

[@BariScienceLab]

You SAVED my life. Thank you.

[@64_bit80]

way clearer than the textbook we had. godsend

[@brightfuture7017]

Thank you so much after 2 days of continuously searching this topic. I didn't get the way other were teaching. Really love the way you are teaching . Thank You so much. Now i got the complex Chain rule for partial derivatives

[@eswyatt]

Thank you so much. I was banging my head against the wall trying to figure out the polar form of LaPlace's equation. The problem was I forgot how to do partial derivatives that require both product and chain rules!
