It's crazy how my professor spent 2 hrs and 15 minutes explaining this with a 15 page long worksheet and I didn't understand jack. You literally taught it in 12 minutes, I love you
Thank you so much, I understand what my calc teacher is talkin about finally! I wish I could give you a big hug, I feel so much better after watchin this
@@IUsePCP in some classes, any test is called a midterm... so if there are like 5 tests throughout the semester, each one is called a midterm even though it's not the middle of the term.
if we get a f"(x) = 0 is there still a possibility for x be to be a maxima or a minima if f'(x)=0 is the change in slope (i.e the second derevitive) of a * maxima * or a * minima * must always be * negetive dec. * or * positive inc. * respectively or can it be * zero * at any of them aswell?
This method wont work if the first and second derivative is undefined i.e. the first derivative would be the next approach if the second derivative test or even the first derivative is undefined Edit: i realised this was 2 yrs ago 🤦♂️☠️
bro i got 53 percentage in my 12th grade cause i dont like math but i hear about your channel and i started to love maths and i got 99 percentages accross my 3 semesters love you bro
Finding the critical points in calculus is kind of similar to finding isoelectric points of an amino acid in biochemistry! Thank you for all your wonderful explanations on very abstract and difficult concepts. You're very good at demystifying them.
9:40 the easiest thing to do is plug in 0. that way, you can cross out all the 'x's and focus only on the signs of the constants. in this case, you have 3 negatives, so you'll get a negative answer after plugging in 0. so the sign between -2 and 1 is '-'. now you can use the multiplicity trick.
1:06 here lies the issue with my highschool teacher ;D, they explain very well everything graphically with simple functions, and the calculations are easy, then we go to functions with critical points that are not extremas, and not defined functions and all that sht and they are like, ey analogically from what we've discussed, like i can imagine graphs as easy as a person who worked this field for 40 years; it is way easier to remember when you study from raw methods, you cant force intiution in student's brain, it is something that develops over time
@@21Screen Pretty poorly. I'm in uni and my gf collapsed with severe chest pains the morning of the test. Had to call an ambulance. Was just worried about her the whole time I was taking the test. Good luck on yours though!
@@hawamusah-opata9799 wouldn't it be "-"? If the power is even, the sign stays the same(like he mentioned in the video). When x is greater then 2, it's negative. Therefore when x is lesser than 2, it's still negative.
he factored it just to simplify and make it easier to solve for x and find the critical point. you should always simplify as much as you can (unless its a super complicated problem and it'll just take you back to the original answer)
Can you find the max and min values of a function with an imaginary critical value? I'm trying to solve a homework problrm but the critical value is the square root of -1 and I'm stuck.
Take note that another way to find whether the point is a maximum or minimum is taking the second derivative and plugging the x value. If the result is x>0 then it is a minimum and if x

8 years later and still the back bone of the education system. You're a G dude.

I'm pretty sure this dude is the only reason that I have any chance at graduating college. Thanks
Same
Exam in 14 minutes 😭
@@gloweyyy howd you do your exam bro

Here I am as a junior in HS, calc really is a whole different animal
Keep up the lessons, you've made a significant difference in my marks. Thank you!

Got a midterm in 10 minutes wish me luck
A midterm in November??

How'd it go? I am going to have my finals tomorrow and I have no idea what this is all about
@@denverdean2663 well, I don't know about him but I had just had a midterm and it went horrible... like really really really bad.
LP? Lmao
you are better than 90% of professors, bless your soul i love you
If you need to find out if it is a max or min, use this: f’’(x)>0 = min or f’’(x)
This is much easier thanksss T-T
I’m gonna try this out on my test which is in a couple hours. I trust you
if we get a f"(x) = 0 is there still a possibility for x be to be a maxima or a minima if f'(x)=0

over the years you have become a father figure to me. thanks for helping me out its hard to find help in the world
I really enjoy watching your videos. They have helped me greatly in the last year or so of mathematics.
Thank you so much sir. You don't know how much you are helping me. You explain better than the book I have
Watching this 20 minutes before my calc final. Thank you sir
You don't need Lecturers... Lecturers need you.. God bless you man
You have saved me so many times, you are the best teacher I have ever had
This stuff seems complicated at first but after a bit of studying and plenty of practice fits together elegantly.

Bro... you r out of this world. Thanks!!!
Thank you. I was struggling to understand this . After watching your video I feel much better.
were you sick?
@@princeequalizer3715 lmao
So clutch. Helping me throughout the whole semester. Truly the goat
20 pages of material in 12 minutes..thank you sir
After 5 years this video is still so relevant wow great job
yea... the rules of math and calculus don't change much do they...
@@natefergeson2390 true lmao
what did you expect
You did a great job with your presentation. Thank you.
lets not skip any ads as a thank you hahaha
locking in for my last 2 calc 1 tests, wish me luck. I will be back in may to let you guys know if i passed or failed the course.
Hold up I gotta lock in too
so brother , passed or failed ???
@@ajaysinghhada1611bro died 💀
Did u pass or fail
update, i passed with a B😂😂. totally forgot this comment
I’m from Taiwan and I think this video is more useful to me than all the other Chinese calculus video

this man is a savior, thank you
Thank you starting to feel more confident in BUS CALC
woooo The Organic Chem Tutor is the best
Thank you so much! I am understanding calculus because of your videos! ❤
We're having midterm exam today so i need to rewatch it again while answering my exam😊😊
bruh
how did it go
I feel like I owe you my tuition for the great support towards my degree😭
i swear I'd give you my lungs you're a lifesaver
idk why or how but this taught me on 5 minutes what I could not figure out from the textbook in over an hour
Sir. MAY GOD BLESS U. U helped so many
and God bless you for blessing him!

Best guy in the world
I wonder how much money he’s saved students from dropping their math classes
I'm convinced that Mark Wahlberg is on the other end of the mic
@baldy hardnut A little bit deeper but not much
@baldy hardnut Cant wait :)
reminds me of the Mark Wahlberg Talks to Animals skit on SNL.
awesome work , really helpful!😃
MVP I like this guy
amazing video. used some great tricks and hacks to get the answers and made everything clear.
thanks man your channel is the best !
organic tutor? thee best.
Thank you very much, very helpful I really like the way you teach
Mid-sem exams in 12 hours. Thank you🥲❤️❤️
Thanks for this video. You make maths very easy !
Final Exam in 6 hours. This man is saving my life.
Your explanation is great
Thank you . It is amazing for both learning and revising!!!!
I love your videos, very helpful to me.

Love it!
Got 2 finals today, pray for me. 💜
Good luck lol mine on Friday
Have a Calc test tomorrow
@@foca7550 Same but mine's tomorrow. A day after yours. How'd it go ?
@@21Screen Pretty poorly. I'm in uni and my gf collapsed with severe chest pains the morning of the test. Had to call an ambulance. Was just worried about her the whole time I was taking the test. Good luck on yours though!
@@foca7550 how was it
Ur such a beauty for these videos
there is a mistake at 10:31. (x-1)^2 has even multiplicity, the sign should be + in the number line
that's true cuz i got confused over there
@@hawamusah-opata9799 wouldn't it be "-"? If the power is even, the sign stays the same(like he mentioned in the video). When x is greater then 2, it's negative. Therefore when x is lesser than 2, it's still negative.
I was looking for this comment. Yes I got confused too. I watched it over and over again.
Thank you sir. I appreciate the knowledge.
You are the best ♥️♥️♥️♥️
i big love to you way of explaining
helped me a lot before my final
Increasin and decreasin
omg you are a wizard!
Harry
Feel free to pause the video
Your name sucks I'm sorry 😐
Thanks man. You've been a great help.
The way he says increasing and decreasing is satisfying for some reason lol
outclass would be a very small word for you. Fabulous
You are a GENIUS
great work!
Wish me luck y’all got my final in 2 hours
Always the best
A- on calc finals thanks to you
Thank you organic chemistry
Your video transfer generation to generation
Been sick for two weeks straight and teacher cutting me no slack. Got a test at 8:30 sharp wish me luck gang
Thankyou soo much this helps me a lot>
Final in 1 hour
What does this even meeeaaaann
😭😭😂
I will pass this class.
thank you for your help!
At 3:49 when finding the Derivative. Did you factor out the 2 to find the dy/dx?
he factored it just to simplify and make it easier to solve for x and find the critical point. you should always simplify as much as you can (unless its a super complicated problem and it'll just take you back to the original answer)
My exam is today wish me luck x
3:28 how can you tell that the critical point is 2?
Oh nvm! I see, if x = 2 then it will equal to 0
Got a final in two days wish me luck I’m so stressed
Very helpful 😇
you are my hero
8:33 but what were the critical points
thanks sir nice explain
I want to ask, at 7.00 where did the number 6 go? on the question after the factor.
Got my Semester final in 4 hrs. Wish me luck guys.
4:39 Plug it in
Simply the best
Can you find the max and min values of a function with an imaginary critical value? I'm trying to solve a homework problrm but the critical value is the square root of -1 and I'm stuck.
What grade are you?
I got a calc final in the morning wish me luck
THANK YOU!
Take note that another way to find whether the point is a maximum or minimum is taking the second derivative and plugging the x value. If the result is x>0 then it is a minimum and if x
