He is dominating KZread 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.

may god bless you....you are making my university life so easy.....

Ive made it to Calc 3 watching your videos, thank you so much. This is my last math class.

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

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

legit 3 minutes of OCT> University professor.

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.

officially my best youtube teacher

You may be somewhere in LA but know that your students are all over the place and they appreciate your efforts. Thank you 🙏🏽

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 KZread TV with the Organic Chemistry Tutor.

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.

your humor is just lovely

You be saving my life I swear

Such an amazing tutor👑

Thank you so much, I was badly stuck on mod problems

his videos will never fail me

Nice. Very relaxing voice.

many examples help A TON

once again thank you so much for the help !!!!

Good keep doing what you are doing

This video is wayyyyy better than the one on Khan Academy

i really like you,re all videos keep it up

Great explanation JG, as usual.

Congrats for 2M subscribers

Great, I was stuck on a homework problem and you solved one almost identically!

I love your videos, in a cool bro way.

Man's a legend

Finally I get it! Thank you!

May God bless you and your family

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??

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

5:30

I was hooked when he didnt redraw the first graph 5 times to get the perfect smoothness. I hate when math teachers do that.

Why wen the derivative happens to be a fraction why do we have to equate them to zero separately??

طالب سادس فضولي 🫣 Thx bro for this video ❤️‍🩹

Can someone explain please how setting it to zero equals it to -1 @ 3:20

@jawadtariq9634

Жыл бұрын

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.

luv it! question though, what's the difference between a critical point and a critical value?

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

@turkeysamr

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

You’re dividing the exponents. So it’s like 1/2 - (-1/2)= 1/2 + 1/2= 2/2= 1

but what happened to the 6 that was factored? 5:15

@Ed95366

2 жыл бұрын

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.

@SM-qn7sr

The 6 is a constant and you can divide it by 0 and it disappears

Only fill the blood applied to you by a time or second you take it in til you rest%accountable

17:20 .......nice

Sir why we compare the 1st derivative with 0

@dfm01000

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.

Cosin of 120( 2pi/3) is also 0.5 (1/2)

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.
