how do I find the limit of -3 in (2-sqrt1-x)/(x+3)?
Interesting
@@Youngballer739 I am getting no real solutions cuz when x approaches 3 in 1 - 3 or any no like 2.99, u get -ve sign under root but that's not allowed in real numbers.
Please explain in hindi

Amazing how he can talk at a slow pace and do more for me in 20 minutes than my lectures in 2 hours
Damn, are the lectures that bad?
@@Some.username.idk.0 uhh yeah, ministry of school is so ill
Education in Poland is No.1. I wish that I could there.
it weird, but he actually talks pretty fast, it just seems slow because he makes long pauses
My teacher is great at teaching but I'm just extremely forgettable so even if I understand it, I forget it after like 2 minutes 🤦🏻♀️
Organic chemistry tutor > my math teachers
BEST TUTORIAL VIDEOS :)!
101% agreed?

Frrr!
Its scientifically proven
The dislikes are from the teachers and professors hating on someone who can teach better than them
On god dude, my teacher cant teach for crap sometimes
@@fahadelchami254 I just started taking Calculus and my professor already started hating on math youtubers lmao
@@kinkyswagfish8005 It takes away value of their career. Imagine in the future, everyone using online tutors instead of showing up to class, because online-enrollment is increasing in high school. My local high school have 200 students in online classes, all tests are scantron and automated. Almost no teacher interaction except messages and occasional meeting. It's happening in every major city.
@@destinilund4771 I think it depends. I don't think their value loses as professors because even if it's online classes, they still have to teach unless the class is full asynchronous, which most people don't take because it requires self learning and a good work ethic. Even if demand in online school increases, they're still work for professors. I think its more of an ego thing. My professor literally said we shouldn't trust youtubers because we don't know if they're teaching the right stuff since most didn't go through the education process like he did
@@kinkyswagfish8005 1 professor could create chapters for high school students in the whole city, those same chapters will be recycled for many years, for 50,000 - 100,000 students. Same answers, same questions, shuffled scantron answers.
Majority of textbooks, normal tests, and exams are created by tenure professors, not high school teachers. Which explains why questions are sometimes very "off" and "out there", requiring thinking skills not taught in class.
High performing students already study answers for tests for in-person classes, leaked by websites. Cheating gets worse with online school.
Search your class course code, test, chapter, month. Some websites have answers to exams.
If I could like this a million times I would. You're singlehandedly carrying my calculus grade
I’m going to come to as well pretty sure he’s gonna do the same for me

nah you're not just listening to your teacher
@@chousana1225 teachers tend to make things way more harder by over explaining some things and under explaining some. I've watched my teacher's teaching video 5 times before saying f it and come here because I couldn't understand
@@sugarsnow2Yeah, true
My math book: literal fucking hieroglyphics
Organic Chemistry Tutor: 20 minutes of pure understanding
xDdd
Thank you man it’s like looking at another language and when you watch a video tutorial it’s like elementary stuff
Are U from Ethiopia?
@@annahwanet767 yes ma'am :D
@@kidus_tv woah.....hahaha nice to meet u
This man deserves an award for how good at teaching he is....making math actually understandable and even enjoyable! Thank you for your service!

This is literally our lesson for this week thanks for adapting to our needs
He actually deleted the original video and uploaded a shorter version to advertise his patreon
You a grade 11 too? 😭😭😭😭😭
i am grade 8 dude
they even started integrations for us
I am grade 7 but like undergraduate maths.I would probably get a PhD for a mathematical related subject
I dont even have to ask questions, you simply just answer them. I dont ever feel lost or confused while watching your videos. Youre doing amazing, love your work! Thank you for helping us! ❤️🔥
Came here with Tha same feeling
You're so amazing! I failed calc 1 in eleventh grade and everybody was so mad at me about it.. 2 days before my exam i found you and i was able to get 14/20 while my past score was 6/20.. I know it still wasn't the best score but as someone who struggles with math A LOT that was like a miracle because before that i was crying for hours since no matter how much i watched my teacher's videos i just didn't understand anything.. Thank you so much ❤️
Calc1 in engineering is way different. You won't be able to pass if you followed this guy. I swear to god
@@HashemAljifri515really? Why not :o
can u give me some recommendations. my first test is in two weeks!!! im struggling with calc 1
@@dimzy4234 Well look I failed calculus 1 last year as a civil engineering student because our professor treated us as engineers. And his mid and final exams were extremely unbeatable, so my advice to you is just carry on step by step and never leave it accmulate on your back and you'll be fine. Just start from the beginning one by one and move on slightly. Do alot of exercises on one topic and try to find the tricks on each chapter in order to be "unbeatable".
Organic chem tutor be out here grinding on new years and throughout holidays
why is it so stressful listening to lectures but it's so fun listening to math tutorials in youtube. thank you very much for explaining everything, i love watching your math vids, so helpful.
Because you want to be here, things done voluntarily tend to run much smoother than by force
I've learned more from this 20 minute video than I have in 2 weeks of calc 1. Thank you so much, my good sir
Two weeks???… A whole semester for me😂
Who else quit the textbook and start watching this
I'm currently taking Calculus 1 this Winter 2021 and this is good timing.
Good luck on your grind! Calculus was the whole reason I switched majors and graduated with a BA in mathematics.
Did you pass the class? I am taking it this summer, Idk if I'm going to absorb all the information in just 1 month :(
@@ianthunder1617 how'd it go? I also took this class for a 5 week summer course and was stressing hard. Passed with a B
@@kinkyswagfish8005 Sorry man i backed on the first day.
@@ianthunder1617 damnnn y
Why cant my professors make lecture videos like this. Everything they do is utterly useless, this man is single handedly helping me pass calc
2:12 I really have to thank you so much for this trick. I used this trick in my final Calculus I examination. I was stuck on my finals when dealing with hard limits but this saved me. Thank you so much for saving me with this trick!
That's really easy! Just use factoring these expressions and solve!
@@yuvrajjha4172 I said hard limits, not (x^2-4)/(x-2). Hard limits that involve arcsin, arccos, cot, sec, ln...etc.
@@larrywong5793 """hard""" limits but you don't know the most basic way to solve them? yeah...
@@getyournekoshere9824 Your reading comprehension is kinda trash
@@getyournekoshere9824 don't be a nerd
It’s how he put all the different types of discontinuities in one graph, so that when you come to discontinuity topic you already familiar with them, he truly is a genius
The reason your videos is are so good is they're concise and to the point, You don't spend time explaining fluff, and show how to do it at each step.
Like in class it feels like you're being taught something completely new and foreign that is hard to take on, and you're learning a bit of a larger picture each time. But here its like, "this is what you have to do, and here's a crap ton of examples."
The only reason it feels different now is because your seeking it out. Your brain is in a different mode, and yes, that's good, but it doesn't mean the Prof or teacher is bad. (All the time)
I still didn’t understand some things tho
this man taught me more about limits than my 1 month of lectures. Wish he was my professor :(
my math professor is good, you just explain things in a very clear and concise way. you help thousands of people, thank you.
MR. Organic Chemistry Tutor thank you for an incredible lecture on Introduction to Limits. These lectures really increase my understanding of the subject.
This outta help out my new engineering buddies, thanks
What do you study
Engineering buddies probably are looking ahead to Calculus 3 buddy 😂
@@joeburreaux7953 first years start here
I just know I'm going to graduate from uni. with organic chem tutor's teachings.
It's a big improvement, concise, increased display of information, higher resolution, better colors, better Audio, very good, taking care of content.
I'm in calc 2 and needed a refresher on limits since we are revisiting this topic. Short and to the point as always, thank you!!
This guy deserves a teacher award, i didn't even get a single idea on math class but this guy helps me more than ever high school teacher i know. He even speak at slow pace so anyone can understand and catch up to the pace.
I just love how he's so easy to understand I've been following him since secondary school
The master has blessed us with another video.
I watched your videos when I was in the 12th grade and now that I am going to the university I will still watch them. Thank you very much for your videos keep it coming.
This man be teaching me every subjects I have 🙌 From my Chem sub to Calculus. Thank you so much!!
Just whyyyy do I undertand your explanations than my teachers. I mean you're better than my teachers. Thank you so much. We are very grateful.
You're single handedly making me want to learn maths more. Thank you sir
Same for me here
you don't realize how many grades you've saved! lol
its 3 mark
I simply cannot believe this guy's level of knowledge. He has helped me in general chemistry, organic chemistry, physics, trig and now calculus. He is fascinating. THANK YOU!!!!!!!!!!!!
Man, every day I get back to his channel his subs go up,
Amazing man, just pure amazing.
This dude teaches physics, maths, Computers and Chemistry, all with the same crystal clarity
Love you
Just learned this today my professor was going way too fast and acting as if we already knew the information
Same!
thank you so much! i hope you're getting all the support on patreon that you deserve :)
my guy is literally changing the world. i got my homework ready to drop the class. i click on you and calc 1 is easy. ❤❤❤
Here I am cramming for tomorrow's calculus exam. Thank you!! You helped me a lot.
Great job!! Please never leave this!!!
This guy is my teacher for every class this semester
thank you so much man. I understand your lectures way more than my professor and you are a life saver.
Thank you so much, please keep up the calculus work. You're better than all our uni lecturers!
For the question at 8:23 (the one with the square root in the numerator), you could alternatively use difference of squares in the denominator with x-9, making it (rootx -3) (rootx + 3). The (rootx -3) can be "cancelled out" from the numerator and denominator, and you can save a lot of time in getting to 1 / (rootx+3) = 1/6.
i was thinking the exact same thing
i know u can do that but he had already had explained that previously so he had to show a new way
With the college algebra I had back in a community college now I can understand this topic very well, wow! Thanks for the video.
Carried me through Pre-cal, and now he's carrying me through Technical Calc. What a wonderful human being.
This is super awesome. I am gradually growing confidence in calculus.
First 2 mins of this was better than the first 2 weeks of my calc 1 class. I’ll definitely be muting my zoom “school” to learn from you! Awesome video!
neither my pre-cal nor calculus teacher explained limits properly, so I have been stRUGGLING this week
so thank you for this :)
Far better than those who called themselves professors or whatever! Thank you, you are the best!
I've learned more within 20 minutes than my 3 hour-long lecture at school. Hope I'll get enough money one day to support this chanel financially.
JUST started learning about this thank you
Perfect timing thanks Sir, you helped me a bunch
You’re a lifesaver, my test is tomorrow and I finally understand. It’s crazy how I learned more in a 20 minute video than weeks worth of limits at school.
😂 lmao
Just the first 20 seconds of the video have given me a better understanding.
damn this is really helpful thanks! Also I like that you go through all the types of questions, so I'm not lost if there is a new type of question and i can't think of the method
This is very helpful.
Very helpful when your Calculus teacher only gives you 10 minutes to read the material and expect you to answer questions under 5 minutes 😅
Or when your teacher doesn't wants to teach you cause is your job XD
Ahhh, love going to my calc class, leaving confused, then watching this channel and kahn academy both explain the same subject but 100x better. Love UA-cam
i love you bro, you got a BIG topic covered in 2 minutes and 20 seconds! THIS IS A SUPERPOWER!!!! THANK YOU
I easily understand this kind of teaching, how wonderful! ❣️✨
I like this way of learning calculus - intro to the limits when the teacher explain it to the students clear and deliberative
Give this guy an award 😂
Went from failing my class to getting a high B just by watching your videos for 2 weeks😭 thanks so much for the videos
You’re gonna do amazing things man. These are so well done. You have a gift.
thank you so much!!!! it’s been about 3 years since i took prencalc and took calculus but dropped after a month, i’m gonna need to take it again, i never understood limits but this makes so much sense!!!!! i figured better start learning it now so i can feel confident when taking it again!!!
Gosh I hate math problems and I've got my Calculus 1 exam in few days. Hope I pass the exam at least 80 precent.
I was reading a textbook and was totally lost. After watching video i have learnt the entire chapter in 20mins. Thank you so much🤩
Can you help mathematic solve problem??
@@elifyardim4242 I could.....
@@jamesjudd1326 help me James Judd i already failed and i am blonde :)
Before looking over this video I was not able to solve a single limit problem. But now I can solve all of it. Thanks a lot.
I love you Organic Chemistry Tutor 😫 thanks for helping me review what a limit is!
Thank you so much for what you do specially in calculus. I have my makeup exam in a month and im gonna eat sleep and breathe with your videos. I'll let u know how it went in a month!
Howd it go? I hope you did well
7 months and to reply sadge
Bro how did it go?
@@davecarlton8354 i think we lost him, bros. :(
شكر جزيلا لك 🌹❤️
Thank you 🌹❤️
Best explainer ever seen. Thanks for your great help
I don’t know what I would do without you man
Wait so every year does he just re-make the older videos?
yep or same video
@@masternobody1896 Sweet, can't wait until the 2025 edition comes out!
I wondered the same thing , I did compare the older and new version a while back, I think the new 1s are actually better ... maybe the difference is not worth making a whole actual new video because all his videos are great
@@azyle2104 Honestly the only difference I saw was the video quality.
@@joeburreaux7953 looked same to me
So you're telling me my professor legit can teach the whole thing in just 3 minutes, but he decides to take 2 hours?
BRO YOU’RE SO CLUTCH. I DIDNT LEARN LIMITS BUT IM DOING AP CALC SO I NEEDED TO LEARN AND IM FINALLY SAVED
Thank you very much, it has been a very professional and thorough course. Keep up the good work!
I thought I was bad at limits, till I saw this video
Thanks ❤
this subject wasn't on our curriculum but i'm curious to know so i searched it up on youtube! now i'm gonna study this during my free time with this channel 💗
Exactly what I'm doing here
thanks for helping so many students across the globe!!!
You are really doing a lot of good works thanks and please keep it up
jesus christ, everyone seems to understand this when he explains it but im still just sitting here lost as to why hes even doing what hes doing
Lol make sure you knew basic maths
@@noname-kx1pl Since when is calculus basic math
@@camolive3727 I meant the process. Getting the gist of it. At least with that context you'd struggle less
@@camolive3727 if you have the time learn the rules of mathematics from primary grade to college. Learned the hard way but it's worth it. Like here he mentioned factoring and rationalizing. That was tackled in highschool if you ever paid attention
@@noname-kx1pl Very helpful🙄
im so thankful to organic chemistry that I dont skip ads
Same bruda
Man is a life saver, thanks for everything man, we appreciate your help, thank you for educating the masses!!!
God bless you for this video. My lecturers couldn't do this for me... Thank you!!
Sa totoo lang may mas natututunan ako dito kesa sa math teacher na nag tuturo ng halos isanv oras na puro powerpoint presentation lang ang ipinapakita. Kaway sa mga Filipino diyan AHAHAHAHA ARAL WELLʕっ•ᴥ•ʔっ
Tinawag pa nilang teacher yung sarili nila e matalino lang naman sila pero hindi naman magaling magturo
Samin naman parang rapper,ambilis magsalita
buti sainyo may presentation eh samin module lang talaga hayzzz

I'm preparing for JEE an engineering entrance xam ....and you are really amazing
questions in JEE are much harder than this.. which grade are you in?
This are just basics, you need you to study the advance calculus
I always look for your videos, for everything. It helps me soo so much at Uni
i love u so so much ur videos got me through all my college math courses ily ily ily !
I just came across your video and I would like to ask if I can equally square both sides for the example on lim x->9 and if yes, I got a different answer 1/18 and yours is 1/6
I was here at: 12th of Jun 2021 at 10:39PM
Studying for G12 finals
Awesome 💯 and perfect ❤️ we're grateful and thankful for the lessons
This helped me alot in my advanced levels ...thank you for ur efforts🙏
i have a 97.7 in calc because of you
wow, from which book did you solved problems?
C’mere for a kiss Mr.Tutor
I started with knowing literally nothing. But I think I got to understand a bit more. Your video is very useful. You got a like and a new sub.
Thank you so much on guiding me in my calculus subject.
