Lately, without fail, my guy has been posting the right videos as I go through the topics in school. Thank you so much my guy

[@lightffx6889]

So fking true bruh

[@jadenkim3178]

Sameeeee

To whoever is reading this, I hope that whatever you're going through gets better and whatever you're struggling with or worrying about is going to be fine and that everyone has a fantastic day.

I'm 39 and goin back to school. I had taken algebra in highschool and failed it basically. Throughout the years of on and off community college, I avoided math like the plague, even taking Math G (math for liberal arts students) where you write ABOUT math. I was terrified. I now am admitted into San Francisco State and the Precalc teacher is the WORSE. Half of the class has dropped out. He doesn't actually teach but just makes us gather in groups for "Labs"(teaching/trying to work out new topics with each other) But the Organic Chemistry Teacher definitely saved me and instilled actual realistic hope in achieving my dreams. I feel so lucky and appreciative. I am relying on him heavily to guide me through these years. I have hope of finishing mainly because he has made these videos.

[@goldenratio369]

You make me actually like math. At first glance, some of these probs can be daunting but the way you explain the process of solving it makes is so easy & beautiful. Thank you

[@axmadyare5772]

You are the one of the best Teachers in UA-cam,
You changed My life , Thank you for your effort Teacher .

[@LmaoMeowz]

Watched 5 other videos didnt even START understanding until this one. One of the best math channels out there! Never disappoints

[@HanzAira]

I love how you post this video today since today is a Sci-Math event of our school and I'm participating in the quiz bee. Thanks for always supporting us✌️✌️✌️

[@chrislombardi7134]

I was so confused while learning in school but this video actually really helped a lot and now I understand it more

[@ndeshi_m_w]

This is an amazing explanation your the type of teacher we need in our school

[@d3generate804]

perfectly timed! this is exactly my A level maths topic right now😅

[@waniaiftikhar635]

I hate lecture but your voice is so calming. it keeps me focused :(

[@Rhealmodiegi08]

Bro your a life saver

[@LiveInTheMoment777]

this youtube channel is single handedly saving my math grade

[@arielbrinson8766]

I need to watch this one more time 💆🏽‍♀️😩

[@Programming-t8o]

Really amazing explanation 😊😊

[@vasitiwaku6336]

Just what I needed thankyou ❤

[@Sca_Ra]

is it just me because his voice is damn cool

[@mohit108414]

That was helpful. Thanks.

[@cesargarcia2310]

What about the range? Hos is it defined in a composite function?

[@NotElayn]

for f(x) = 4x/2x+1 , x can be equal to 0 since it wont be undefined. so wouldnt its domain be (-infinity, -1/2) u (-1/2, infinity)?!?!

[@AceOfHearts001]

Very nice and useful. Thanks.

[@kooljosh3511]

you’re goated

[@lonelystone1132]

dude be teaching better than IIT professors:))

[@elbilala]

Am here for my tommorow maths test😂😂😂

[@reverse5906]

What happens tho when f(x) itself has a restriction?

[@SuperYoonHo]

ur awesome man

[@Kingslayer474]

More Calculus II videos please

[@nifesimikotun6313]

This is not Calculus II it's precalculus.

[@Kingslayer474]

@@nifesimikotun6313 I just stated that I wanted more Calculus II videos in the future. Don’t see anything wrong with that.

[@kanjakan]

@@nifesimikotun6313 He didn't say that this was a Calculus II video?

[@yrew2004]

Thanks sir

[@watchoutforcopyright9339]

what applications can we use involving domain and range?

[@UmarFarooq-rn3wu]

Amazing boss

[@quinnpritchard8947]

6:18 Why wouldnt the restriction x != -2 also be in the domain?

[@nanribetishaya4029]

Why did you change the direction of the inequality?

[@zohairhussain8005]

Fourier series pls

[@tommymaguire7378]

how can the denominator not be 0when its 2/x-3?wouldn't it just be -3

[@k.p6582]

What about range puth?

[@sap2472]

Please do on eigenvalues and eigenfunction 😸, many thanks.

[@AydenRiley-r9r]

Dawg you made me more confused get to the point

[@sk8n854]

"And it makes sense"
No man... it doesn't. Lol.

[@shorttricks3153]

But what about range 😢

[@budgielove17]

I love u
