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.

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

[@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

[@Vener349]

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.

[@LmaoMeowz]

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

[@chrislombardi7134]

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

[@axmadyare5772]

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

[@nekochan4280]

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✌️✌️✌️

[@ndeshi_m_w]

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

[@waniaiftikhar635]

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

[@Sca_Ra]

is it just me because his voice is damn cool

[@d3generate804]

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

[@elbilala]

Am here for my tommorow maths test😂😂😂

[@Rhealmodiegi08]

Bro your a life saver

[@rajeevkumarbhagat2160]

Really amazing explanation 😊😊

[@arielbrinson8766]

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

[@mohit108414]

That was helpful. Thanks.

[@vasitiwaku6336]

Just what I needed thankyou ❤

[@lonelystone1132]

dude be teaching better than IIT professors:))

[@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)?!?!

[@SuperYoonHo]

ur awesome man

[@cesargarcia2310]

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

[@AceOfHearts001]

Very nice and useful. Thanks.

[@MM1771.]

More Calculus II videos please

[@nifesimikotun6313]

This is not Calculus II it's precalculus.

[@MM1771.]

@@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?

[@kooljosh3511]

you’re goated

[@zohairhussain8005]

Fourier series pls

[@UmarFarooq-rn3wu]

Amazing boss

[@sk8n854]

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

[@watchoutforcopyright9339]

what applications can we use involving domain and range?

[@nanribetishaya4029]

Why did you change the direction of the inequality?

[@user-bf6je7co9m]

Dawg you made me more confused get to the point

[@quinnpritchard8947]

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

[@yrew2004]

Thanks sir

[@k.p6582]

What about range puth?

[@tommymaguire7378]

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

[@sap2472]

Please do on eigenvalues and eigenfunction 😸, many thanks.
