you’re a legend, thanks for making the one good video I’ve seen on this concept.

Why does the figures look like underwear? Panties with popo holes?

The chart really helps thank you!

Thanks

Thank you!!!!!!!

Which software it is...

Calculate Shell /Cylinder Volume in Cu meter and convert to Cu Ft th-cam.com/video/pexzGbJCTNE/w-d-xo.html

very good clear precise and cute explaination loved it

nice video from venezuela, was so helpful

thank you!

Madam, thanks a lot. you just solved my confusion. AND I left with my thumbs up

for the Vertical Axis- Disk Method, as she's drawing the representative washer she gives some sound effects: "there's a hole in the center "shoop -shoop"!!! 😉 Made me smile

Excellent explanation thanks very much

very helpful!

Is there a link for the applet?

that thing look like underwear

Oooh, very helpfully

thanks

Gracias me ayudo mucho?

Super useful! Best explanation I've seen on this topic, thank you!

this video is clear and explains the little things along the way that helps a lot.

it took me forever to find a good explanation for this concept! thank you so much for making this.

The video just ends at 20:55 for me??

thumbnail looks like パンツ

Disc/washer: your small rectangular element is perpendicular to your axis of rotation Shells/cylinder: your small rectangular element is parallel to your axis of rotation

I need to write a report on this site, but I do not have sources. I need these sources, please

Little did you know 5 years ago that there would be a pandemic and us calc students would find ourselves trying to learn this without an actual professor teaching.... So thank you for being the lifesaving virtual professor!!!

thank you!!!

Thank you!!

ily

Very good explanation!!!!!!!!! good idea to put the different forms up next to each other. gives one a better overview!!

I'm sorry but I find many different sources and all of them have different definitions of R and r. Can you please define them according to the formulae you presented? Thanks!

FLIPPING AMAZING!

It is the best explanation that I have seen on videos. Excellent! Thank you.

Thank you, very useful video, nice explanation.

This is much better than most videos I watched and makes sense but for some reason my brain can't process. Calculus 1 was so much easier than 2 and if you guys are average in math please don't take Cal 2 in summer

Thank you for your great video! I still have problem applying these to real qns but I will figure it out! thanks!!

Finally, this is super clear, better than khan, thanks

Dr James, Can we use L'Hopital's rule to prove what the limit is or is it just a method for calculating limits? For instance, since you have to know that the Limit as x goes to zero for (sin x)/x is equal to 1 to prove that the derivative of sin x = cos x, is it proper, in a proof, to then use the derivative of sin x with L'Hopital's rule to show that the limit of (sin x)/x is equal to 1? I hope this question makes sense, and thanks for posting these videos. They are very helpful!

Really lucid explanation! If all teachers were as good at explaining as you, no student would have to fumble with math and end up hating math!

The shells are inside-out The disks are stacked

Thank you for posting this! The chart makes a lot of sense and it's so much easier to memorize.

This made so much sense. Thankyou!

Thanks so much for sharing!!! I know it's a few years old but still helping people our a ton :) this made my life so much easier

Shouldn’t delta y be dy in 4:47

THANK U
