Flow chart is awesome. Definitely using this. Thanks!

Thanks. The best tutorial I viewed so far. Keep it up:)

Oh my god, it's a very difficult material but you manage to simplify it. What a phenomenal video. You've just helped me to understand the materials under 15 minutes. This video deserves to be on top of the searching lists so that people can notice it. You have just saved me and my friends to comprehend the topic. Hopefully, you'll become one of the best math youtube channel tutorials in the future. I'll be watching A.S.A.P. Thank you so much 😃.

if the curve is xy=1, is the strip vertical or horizontal?

I wish I would’ve found your account sooner! You are TRULY one of the best at teaching Calc II! I’ve struggled for years trying to understand and got it instantly when watching your videos. You’re amazing and thank you so much for your work! :)

Excellent explanation🎉

Bless you oml you are such an easy person to listen to. Was reviewing for calc exam soon and this video summarized one of those sections extremely well!

OMG THIS IS AWESOME U R AWESOME THANK U SM MUAHMUAHMUAH

This flow chart is a life saver for Calc! Thank you so much for creating this. I really appreciate it.

I immediately lower the volume of my device when you're about to draw a strip haha anyways, thank you for this, you delivered this concept well that made calc2 becomes easy

I understand it from u

Thanks❤

Thank you so much! This has been the best video on describing volume, you've helped me tremendously. My grade thanks you 😭✨

Unironically one of the most clear and concise calculus videos I've ever seen. If you aren't already you should consider teaching.

Thank you so much, your step-by-step explanation is incredibly helpful and makes this topic more clearer. Love the content!

Thank you soooo much

Thank you so much.❤

Bless your soul 😭

I just learned so much it's all clicking now!!! Thank you!

Thanks so much! This was so well formatted and easy to understand!

Oh my god You are my god

i have exam tmr and this literally saved me !!

The hidden heroes of CZcams strike again! Have my first calc 2 exam in two days. Thank you so much!

What would u do to figure out where the strip is if you have an x= and y= equation? Is it horizontal or vertical?

I have to say, well done. This will help a lot of people.

what an absolute GEM of a video, thank you!

most under rated math video

Thanks for your explanation but I have a question You said that in the x-axis y is always 0 what about when it comes to y-axis what x will be?

Thanks alot maaam

This is the kind of teaching I can learn from.

Great work❤

thank you sm!

Your saving my calculus 2 grade! 🙏🏽

I APPRECIATE YOU SO MUCH, it’s been challenging understanding this concept in class but your videos help so much!!!

This is probably the third time I commented on a CZcams video in 10 years. I just had to, this is amazing. Calculus 2 is known to be one of the hardest classes you will ever encounter but you did an amazing job at explaining it. I am going to show this to my teacher because it's just too good. Thank you for the hard work you put into this video.

THANK U THANK U THANK UUUUUUU IYSM FOR THIS VID

excellent video thank you

how is she only has 808 subs, you ungrateful brat, subscribe!

Thank youuuuu so muchhh ashley! i was having a problem in picking which formula to use. Your way has solve my problem,lots of love to you^^

God bless you 🙏 perfect way to learn.

Excellent! It's been a while since I dealt with solids of revolution from calc 2, but I needed to review this topic for something. I programmed the formulas in my calculator, and the only thing I needed to remember is when to use washer vs shell. This video cuts to the chase and is more helpful than any other I've seen. However, I think there's a simpler way to think of it. I only have two programs for this in my calculator -- one for washer, one for shell. There's no need for "disk". Disk is just a variation of washer. In my washer code, I enter a value for any separation from the rotating axis. When there's no separation, the value is 0 (creating the "disk"). This is also how I've seen it taught in various calc 2 texts -- just washer vs. shell. I think it's easier to think of two choices rather than 3.

Amazing video, explained everything super simple and easy to understand

This was beyond helpful!! Thank you so much

Kudos!🎉❤ Thank you!

u just saved my life i love you

It is the best video for distinguish between disk, shell and washer method. Nice explanation 😊😊

this helped so much you don't understand

Why didn't my calc teacher explain when to use horizontal vs vertical slices... thank you for explaining
