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

[@gilmaferrer6488]

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

[@theyxaj]

FINALLY THIS MAKES SENSE

[@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!

[@ayoubelfadil919]

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

[@wigglermain]

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

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

[@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.

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

[@siphilipe]

And why we call it washer?

[@HK-sw3vi]

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