seriously teared up at the end . I have been struggling & so frustrated trying to understand how to determine the radius and what "In terms of x and y " really meant. Throughout the entire video every single thing finally clicked and came together. I just want to get my engineering degree, so i can make good money and donate a bunch to you.... you deserve the world with how many student you help year after year. Thank OCT! <3

Why are even paying expensive college if we are gonna come back to this dude to make sense of the nonsense that our professors teaching us. Dude deserves a GRAMMY. THANK YOU SR

WHAT!? still searching videos for math help? are the videos from 2006 really helping? Are you tired of videos not getting you anywhere in math class?
No I got The Organic Chemistry Tutor helping me

Currently taking an accelerated Calculus 2 class over the summer your videos have been so helpful. Thank you for being so clear and concise.

Finals in 8 hours, bout to pull my second all nighter in a row! Also this video made the way my professor taught us seem just straight up outlandish compared to how easy this was to understand. Thank you so much for the help and great video!

You are simply a saving grace for Physics and STEM students.

I watched your old vid awhile back last summer. You helped me get an A in calc 2. God bless brother keep working hard.

[jokingpirate]

I got a B in calc 1 because of you ! Now I'm back for calc2 ...thank you so much ❤️ i hope when I get my degree and work I'll be able to donate to your channel ❤️❤️❤️

You really know how to teach well and effective. I didn't know even the basics about the disk method. Then I watched your video and did the examples and watched as you solved them. I even solved the last one without writing anything down. You really teach well. Thanks a lot!

[Antimatter]

Definitely need this for the calc 2 test tomorrow. Thanks!

[TheCmart]

[classymemer]

Great work! But I think you have only discussed disc method in this video. Where is the Washer method?

[Kaptiv]

Calculus 2 final in 5 hours. If I pass, I pass the class...if I fail, I have to retake the class in the summer. I wouldn’t even stand a chance if it wasn’t for your lectures. Wish me luck!

If I am not wrong, you have also made this video earlier. I think you're making this again to provide the concept in better quality. Anyways, thanks.
