@@serynaayala9740 it’s not free
Thanks sir ,more and more..I love yo explanations.
How can i get them all all physics and calculas and how many cost can any one tell plzzz?
@@farhatnazlee2954join his patron.
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!
Hang in there. Most important thing you can do is find the right resources and put in the time. Keep at it and best of luck!
I understood it immediately thanks to Dayv you are being brainswashed AND YOU WILL CRY FOREVERR!!! NOW!!!!!!!!
FACTS
Good luck!
Currently in the same boat, I don't understand what dy DX means but I understand the rules and all and ap test is tomorrow!
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
“Nonsense” 🤡
fr fr fr
@Harry Snothead Even if you have a great professor, it's still highly advised to watch OCT and Khan Academy to keep things fresh in your head and maybe even get a different perspective that clicks better.
Bro fr
why a grammy lmao
dont even attend my calc 2 lectures anymore this is all i need bless you sir
I can't understand a thing my calc 2 professor says
@@stevensoublet1977 yeah that's me with my physics professor, ugh.
@@toastedsniper9248 I had a chemistry teacher who spoke an extremely thick indian accent. He also gave the impression he didn't like being interrupted during lecture, for any reason. If you have a question, save it for the end of class... It's a bloody miracle i passed.
@@n0nexreb0rn4 yep. mine is russian with a very thick accent. if you have questions the dude yells at you.
Right? Like it isn't even my professors thick accents. Like they just don't ungabuna the method enough for me.
Finals is in 16 hours. Wish me luck :3
Edit: I Passed!
Gud luck
Good luck bro
Remember, even if you don’t get the score you hoped for, it is NOT the end of the world.

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
Well, you know what they say about math from 2006!!... Nothing cause math is math.
Big agree there. As well as Nancy Pi, Kahn Academy, and Krista King Math. That commercial gets on my nerves so much
@Johnathan Remington That's probably a scam. I've seen this before. Both thaddeus and johnathan joined on March 6 2021 with completely normal names and no profile pics. They're bots. I saw something like this before in another comment section but with free ipads or whatever.
DUDE THAT COMMERCIAL ACTS LIKE MATH HAS CHANGED SO DRASTICALLY SINCE 2006
dude I just got that ad like 2 videos ago💀
What was said in 1.5 hours in lecture has been summarized in 20 minutes and efficiently shown! Another win for OCT 🔥
Currently taking an accelerated Calculus 2 class over the summer your videos have been so helpful. Thank you for being so clear and concise.
Same, I had to retake it this summer and this time around I've been watching these videos. So far I've been doing much better.
Bruh summer calculus II has been kicking my ass. I missed the first week and I have to catch up even though we’re doing one section everyday 😭
Hang in there everyone! Yes it may be hard but it will also be over before you know it!
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!
Lmao I have my final in 20 mins
@@adnanmohammed4354 how'd it go?
@@leggomaheggo decent. Will probably get a 93-94%. It was my final exam and I'm hanging on the edge of AB and A atm
This is about where I’m at right now. Studying for the BC test on the brink of tears
@@adnanmohammed4354 how is 93% “decent”?
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.
Calculus is introduced to you in which class or age?
@@ALCHEMISTaspirant i think it is normal to have your first calculas class in college so depending on where you start. I would say 18-19 if you go to school straight out of high school.
@@ALCHEMISTaspirant Depends on where you live and what school/college you go to
For us calculus is taught in the 1st year of high school
I need help 😭
Who read this as dishwasher method😂
Me lol
me..
haha
Uhu it isn’t the dishwasher method????
Me😂
true
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 ❤️❤️❤️
Ayee! Same here good job fam
Who is excited that he is finally back? Just came to check if a new video was posted. As always thanks for a great explanation
"I am excited that he is paywalling his older, better videos"
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!
Definitely need this for the calc 2 test tomorrow. Thanks!
how is calc 2? im taking it next semester
@@natsumesflowers7152 I'm just barely passing at the moment. When you take this class I recommend after every lecture practice for atleast an hour what you learned including perhaps watch one of these videos of what you learned. Wish you luck.
@@natsumesflowers7152 You doing good bro?
@@natsumesflowers7152 yea u did good in calc 2?
@@clearflow7925 man i got away with a D 😭
Taking calc 2 online and over the summer. This is a godsend. Thank you. 🙏
i remember u.. u once saved my life.astagfirullah,Allah saved my life by u. how are u doing?
i love all ur lessons.
hahaha xD
Great work! But I think you have only discussed disc method in this video. Where is the Washer method?
CALCULUS EXAM TOMORROW RAHHH
Thank you for helping me pass Calc 1! I'm grateful that your channel covers Calc 2 and 3 as well!
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!
I wish you well.
LITERALLY SAME LMAO. Calc 2 final in 5 hours
@@Kevin-ep8sy Goodluck Kev, you got this!
mine is in 9 hours and i think I'm going to fail and have to retake in the summer lmao
How did it go?
damn ngl your voice is so soothing and the way you explain this is soooo clear. a big thanks to you my man.

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.
Nope, he simply edited this video and removed a lot of the examples. The old unedited one is on his new patreon.
Literally just got back from my first day of Calc 2 at college and I was so confused. You're 20-minute video was about 50x better than my hour-long lecture!
to those taking the ap calc ab exam monday- good luck :D
i believe in you
Thank you so much😭😭 praying all goes well for you too if you’re taking the exam monday!!
Bro I just started studying and I have to take that test in 4.5 hrs
correct me if I'm wrong, but isn't the washer method the one that involves two functions on the graph (ex: y = 2x, y = 5x + 1)? If so, I didn't notice the washer method in this video, only the disc method.
You are right but they are basically the same thing anyway. As you said, the washer method involves two functions and you apply the disc method twice and substract the little one fromm the bigger one.
@@paulagaona9622 nope they aren't.
washer method covers rings, disc method covers ,well discs and shell method covers both.
Finals is in 12 hours, wish me luck
I hope made it bro
finals in 3 hours 🥰
Math teachers and physicists HATE him!
Watch as he condenses 4 hours into 20 minutes!
hello , can i please confirm that he only showed the disk method in this video right cuz i cant see washer method .
@@angelbisla6369 iirc he did both
I literally misread the title as "dishwasher"
The best calculus tutor ever❤ didn't think that it's really possible to explain 1,5 lecture just in 20 minutes. Unbelievable ❤😍 thanks a million
Professor Organic Chemistry Tutor, thank you for a detail explanation of the Disk and Washer Methods in Calculus Two. Drawing the graphs of different functions in order to compute the Volume of a Solid, increases my overall understanding of this topic from start to finish. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
Hey man! We may not know each other but I want to thank you for your efforts to make the math more understandable. I used to hate math, but my dream is to become an engineer. As time goes by, I learned so much because of your videos and clear examples. You're such a blessing for us. (Sorry for the grammar)
wow i cant believe my luck! my favorite math channel uploaded this on the same year that im learning this stuff! :D if i'd been born a year earlier, i definitely would have failed this in lesson xd
We just learned this unit today in class. This is such a better explination
Instructions unclear, my dishwasher is now my maths tutor
What
yo? 😳
@@Murtexel What
@@HassanHussain-dg4se lowkey need that dishwasher tho
Wow, this is convenient! Right before my test for this too!
seriously how can i go to my class and hear my professor teach after watching your videos you are a legend man
taking my ap test in eight minutes. god bless you for making these free
Watching these videos instead of my hack of a professors videos
This man single handedly carried me through calc 2
my exam is in 3 hours now AND YOU'RE A LIFESAVER I SWEAR
did you pass
hello , i wanted to know one thing, in this video he only showed the disk method right? cuz its written in the title as both disk and washer method but am i the only one who cant find the washer method throughout the video
@@angelbisla6369 disk and washer are just two names for the same method
@@anthonygriffiths58 YESSSS I PASSED
I am learning calclus as a passtime having graduated 9yrs ago with Degree in Industrial Chemistry. I find it funny at the many hours I spent trying to understand calcus, yet, now everything seems so easy like a piece of cake. It was a tough time for me but I somehow managed excel in my exams despite the challenges.
You make everything question look so easy.. I love this videos!!!
Wish I knew about this earlier 😭😭❤❤
Why go to class when you can just look up the topic of the lesson on the OCT channel? Fr saved me on multiple tests because of the simplistic and easy to understand explanations.
This video made everything click for exam #4. I had to grind my teeth first and try to learn on my own and this video just pulled everything together. God bless you brother 🙏🏼 thank you
Pls if you can help me as well how did the graph at 8:38 were like down and other ones were up? When do i have to draw it up and when to down? Pls if you can just help me with this 😢😢
The fact that I have had this tab open for the past 5 days is disheartening... Imma wait till Saturday night to watch it
Is it possible to put the long version disk washer method back? There are so many problem-solving practices. Thank you.
How does he explain it better in 20 mins than my professor in a 2 hour lecture? I should be paying this guy tuition not my school
isnt this just the disk method? where is the washer method in this video?
Bro you legit carried gen Zs to degrees. We applaud you, thank you
You never showed the washer method in this video.
Thank you 💗
From Iraq 🇮🇶
my teacher is ass and im taking calc 2 over the summer and you are my saving grace 🙏🏽
Super great video! But doesn’t this video only cover the disk method and not the washer method?
I think the washer method is in the full vid you need to pay for
I LOVE YOU SO MUCH THANK YOU FOR MAKING THIS VIDEO IVE BEEN TRYING TO LEARN VOLUME ACCUMULATION FOR THE PAST LIKE 7 HOURS I CANT HANDLE THIS I LOVE YOU
Man you're literally a genius... can I marry your brain?
watching from south africa...this is more than enough sir
hahaha ....missed the entirety of my ap calc lessons and i have a final in 6 hours, hopefully i pass because of your videos :,) ty
Firstly I want to give thanks for you.After I started watching your videos on maths and physics I understand well.
Best channel on youtube
You know that the video will be useful when you see those different colours on the cover of the video
absolute life saver, I was absent the day we learned this. my teacher doesn’t have notes and doesn’t show all the steps or explain anything at all. thank you 😅
This man deserves the world
Honestly been pretty nervous for uni calc but taking the calc bc in hs rn and these videos makes me think calc 1 and 2 will be a breeze for me since I've learnt almost everything already and understand it well.
you are amazing. my professor have videos but i dont watch them cuz i dont understand but instead i watch yours and now i understand everything. and i am actualy having fun doint this.
I am taking Calculus 2 this coming semester. Thank you
JG has done more for me than any college course. Algebra, Calculus, Chemistry, Physics. This guy is a saint among men.
bro just who are you, you have all the videos that i need
For 19:20 doesn’t 3/2 squared mean 3/2 • 3/2. Am I wrong?
you helped me pass calculus last year
This is the hardest one in calc
Bro thank you for my first degree
I need to give this man my money! I am actually understanding math now
u saved my life
Bro, what happened to the old videos the ones that were 45 min and 2 hours long? Every time I wanted to make sure I was on point I used to look at them, stop the video, set up the integral (look at yours) and then go on to the next. Please bring them back.
I think they're all on his patreon now and you will have to pay a fee to access them
Luckily I downloaded almost all of them hahaha 😂
@@illumonousinferno2521 aye send me them?
@@enoughnonymity I wanted to but I think you should be considering to support the channel on his patreon, he deserve all the blessings
Got a calc 2 quiz tomorrow on the Disk Method and Slicing Method, wish me luck!
You are an absolute saint
thnks for this......
I saw another guy saying he teared up. So did i. Thank u
you are a lifesaver good sir. A gentleman and a scholar
Exam on Friday. Calc 2 LETS GOOOOOOOO
"Now it's your turn" sounded so funny 😆 😄 🤣 😂
YOU'RE A LEGEND
I love this guy but it says disk and washer method and only goes over the disk method :(
Could you please upload the washer method intro for your followers without membership?
this guy makes calculus so easy to learn.
There’s no washer method??
Washer is what they call it on the Y axis I think. Not sure personally but thata what I thought
What are the odds this video is created only a month before I needed it?
11:40 the points are x=0 & x=4 plz correct this question. Thanks
And you are a good teacher. Always be happy 💕💞❤️💗💞💕
The question stated that it's x=0, and y=4 and he converted the parabola to be in terms of y so that he would integrate since we know the bounds of the y axis. I don't see anything wrong
You are a saint. God Bless you and your family man. You have saved me more times than I can count.
I’m taking a Calc II summer course soo we have to CRAM work in but this helped tremendously!!! Finally can do my work and not break a sweat 😅
I'm kind of sad that you're not uploading the full video again, for free... I would be very delighted to cover the harder problems in the latter part of your videos, but i guess you also need to monetize your hardwork. Anyways it's still a big help ty
This guy deserves a medal from the president
My final is in 35 minutes. Thank you for making me understand concepts that my teacher can't teach me
This man is one in a million...
Oh my gosh.....it all makes sense now
My CIS Calc final is in 4 hours! Thank you so much for helping me through this
calc 1 final coming up. you've helped me squeak by this semester
Thank you
