He is dominating RUclips right now. I think what make him great is that he is not trying to show that he well master the material, he just being a genuine teacher, really wants his students to understand.
Hey man, thanks for your help. I love how descriptive you are and how you share multiple resources if something is not understood. You're a great teacher.
Thank you so much for this video!! You helped me completing one of my homework questions and better understand how to find a critical number of a function.
Another interesting way to solve the absolute value problem is to realize that |x| = sqrt(x^2), and finding the derivative that way. Derivative of |x| would be |x|/x, then just use the chain rule. I thought that was an interesting alternate solution.
Professor Organic Chemistry Tutor, thank you for an exceptional video/lecture on Finding Critical Numbers in Calculus One. Finding Critical Numbers is important in all levels of Advanced Mathematics. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
i wish you have covered the trig functions with a coefficient. trying to find zeros of sin(3x) for 0 less than x less than pi..... the anser is pi/6 and 5pi/6 but i dont see how... little help anyone??
A year later and I shall answer you, It is a product thats the equivalent of 0, we know that if a product of something is 0 one of the factors or even multiple is 0, 6 is a factor too, but it's a real number, so the only factors that can be equal to 0 are x-2 and x-3
Don't know if this comment will help now but, he discarded the 6 because he wanted to find out what the x's have to be to make the number in the parentheses become zero. If one number in one of the parentheses becomes zero then the whole equation will become zero because zero times what ever number will automatically become zero.
No he is nota regular human benig . I get high not in the exam because of him . He is not normal he was never normal he is always a great person. English is not my first language but I can understand everyo he is explaning easily because he is great .
On example 2. If you factor by the quadratic formula, you get x = -2 ; x = -3. Unless I simply just made a simply math error. I believe the critical numbers are -2,-3. Please correct me if I am wrong.
Hello Mr Donʼt you have videos on Structural Analysis: Shear Force Diagrams, Bending moment Diagrams, Deflections of beams, Method of sections of finding internal forces and More? Please...

How did u get 0=x+1

This is very true!
may god bless you....you are making my university life so easy.....
You are the only thing keeping me from failing my calc class
do you know the soccer player, Robert Lewandoski?
@@JuanLopez-nx5dy Unfortunately, no

Hey man, thanks for your help. I love how descriptive you are and how you share multiple resources if something is not understood. You're a great teacher.
I've taken calc 1 twice now, I did it in high school and now in college, both times I've used this channel to help study for the tests
Ive made it to Calc 3 watching your videos, thank you so much. This is my last math class.

God bless you, bro. You've been teaching what I don't learn in class for two years

officially my best youtube teacher
legit 3 minutes of OCT> University professor.

You may be somewhere in LA but know that your students are all over the place and they appreciate your efforts. Thank you 🙏🏽
Have test tomorrow, video was helpful. Thank you.
I got a 100 on my calc exam thanks to you 🙏thank you for these videos.
All my calc exams have only been 50 minutes and had over 30 problems. No one is passing and the average grade is a 33. College is great.
Such an amazing tutor👑
your humor is just lovely
You be saving my life I swear
his videos will never fail me
2:04 "set the numerator equal to x" - don't you mean equal to 0?
He did to zeeo that's how he got -4
I'm at home sick and this is really helping me keep up in class.
in 15:14, why does the 9-x stay? Wouldn't it be just 1 since you are pulling out the (9-x)^1/2
that was what i was thinking as well, did you figure out why
This video is wayyyyy better than the one on Khan Academy
Nice. Very relaxing voice.
Your voice is amazing.
Thank you for the explanation by the way.
many examples help A TON
May God bless you and your family
Thankyou sir ❤ from india
So whenever you are finding the critical number of a fraction/ rational function you set both the numerator and denominator equal to zero?
Yeah
thank you for helping me find the crit
Congrats for 2M subscribers
May Allah bless you for being such a big help for us!!
Thank you so much, I was badly stuck on mod problems
From this point forward, I hope you find close parking spots on the days you're late for something.
I will never stop turning to OCT videos to save me
You are doing Gods work!
Chill
Good keep doing what you are doing
i really like you,re all videos keep it up
anyone else trying their hardest not to fall asleep trying to do their homework?
You helped me earn a 100 on my differential calculus exam
Great, I was stuck on a homework problem and you solved one almost identically!
i wish you have covered the trig functions with a coefficient. trying to find zeros of sin(3x) for 0 less than x less than pi..... the anser is pi/6 and 5pi/6 but i dont see how... little help anyone??
Man's a legend
17:22 i think root of 9-x^2 had been smaller than 0, the interval would been critical. Am i right? Should we have considered this situation?
yes
plz do more on integration
organic chemistry....
Great explanation JG, as usual.
This man is the only reason why I understand CALC
طالب سادس فضولي 🫣
Thx bro for this video ❤️🩹
once again thank you so much for the help !!!!
At 2:05, what do you mean by, "if we set the numerator equal to x"? Did you mean "set the numerator equal to -4"? I'm confused
If he solves the top of the equation as in 2x+8=0 and solves for x it'll be -4, at least that's what I'm guessing lol
Why wen the derivative happens to be a fraction why do we have to equate them to zero separately??
god bless this channel
saved me from despair.
A vertical asymptote counts as a critical points?
You. Are. The...BESTTTT.
I love your videos, in a cool bro way.
Thank you bro
May Allah bless the great job yours bro.
he is not muslim so respectfully stfu
@@issayahya625 so what? can he not wish him health? muslim or not... tf
Life saver! Can you help me out with this equation- find the critical points for 9e^x-e^3x+6
THANK YOU
thank you so much.
Thank you so much because I loss three mark in 12revision exam .thank u
17:19 Nice
thats wack. lol
at 19:40 isnt 1/2 divided by -1/2 gonna be -1? Why is it (9-X)^1
14:40
You’re dividing the exponents. So it’s like 1/2 - (-1/2)= 1/2 + 1/2= 2/2= 1
Bro came in clutch
Could anyone write trigonometric lesson that this brilliant teacher has shown last 2 minutes
he is gay
@@issayahya625 what do you mean, ı could not understand ?
Can someone explain at 5:19 why we ignored 6?
A year later and I shall answer you,
It is a product thats the equivalent of 0, we know that if a product of something is 0 one of the factors or even multiple is 0, 6 is a factor too, but it's a real number, so the only factors that can be equal to 0 are x-2 and x-3
Sounds like lil Tecca is teaching me math lmao
Only fill the blood applied to you by a time or second you take it in til you rest%accountable
Finally I get it! Thank you!
but what happened to the 6 that was factored? 5:15
Don't know if this comment will help now but, he discarded the 6 because he wanted to find out what the x's have to be to make the number in the parentheses become zero. If one number in one of the parentheses becomes zero then the whole equation will become zero because zero times what ever number will automatically become zero.
The 6 is a constant and you can divide it by 0 and it disappears
19:00 why are we dividing -sinx when there’s a sum(or substraction) there?
That's called "factoring".
luv it! question though, what's the difference between a critical point and a critical value?
Stop honoring him.. He is just like everyone else a regular human being.
No he is nota regular human benig . I get high not in the exam because of him . He is not normal he was never normal he is always a great person.
English is not my first language but I can understand everyo he is explaning easily because he is great .
you a hater
On example 2. If you factor by the quadratic formula, you get x = -2 ; x = -3. Unless I simply just made a simply math error. I believe the critical numbers are -2,-3. Please correct me if I am wrong.
17:20 .......nice
Thanks man
i was about to fail my upcoming test until i found this video holy crap thank you!
Whats the difference of critical point and critical number
2kg
Really man
Can someone explain please how setting it to zero equals it to -1 @ 3:20
You subtract both sides of the above equation i.e 0=x+1 by -1. Thus, 0-1=x+1-1. The 1s cancel each other out leaving behind: -1 = x or x=-1.
is "e" a local maximum
May you live long
Hello Mr
Donʼt you have videos on Structural Analysis: Shear Force Diagrams, Bending moment Diagrams, Deflections of beams, Method of sections of finding internal forces and More?
Please...
Please google lectures by Jeff Hanson for this material.
Cosin of 120( 2pi/3) is also 0.5 (1/2)
Why can't you be my professor
Accountive
Sir why we compare the 1st derivative with 0
Because it's the only way to find the critical number/numbers
Because when the derivative is 0 there is a horizontal tangent line where the slope is 0.
17:19 nice
Still not watched full 😭
I really have hard time understanding polynomial graph.
why cant x = 0 when sinx = 0
BLESS
great vid but please fix your volume. I have to crank mine up, then I get blasted by an ad
i think you have a mistake which is that you let the denominator equal to zero and that is wrong, cause it can never equal zero !!
Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations Congratulations
