Disks vs Shells

[@deannaa2297]

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!!!

[@MrKalebur]

This was actually really clear and well drawn out with a simple explanation to follow that is easily understood, amazing

[@wannabeharbinger1212]

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!

[@wigglermain]

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

[@gilmaferrer6488]

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

[@ayoubelfadil919]

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

[@theyxaj]

FINALLY THIS MAKES SENSE

[@fey0217]

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

[@Pariz144]

[@ricardoalvarez4976]

[@khalilrouatbi6345]

[@deennapirilli3823]

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

[@Lostwolf16]

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

[@stebe12]

Currently doing this in Calc 1.

[@arfanm9440]

This explains really well! Thanks a lot!

[@FaiGal]

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

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

[@theoriginalG99]

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!

And why we call it washer?

[@HK-sw3vi]

a washer is a disk without a center, like a CD.
