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

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.

how's it going

[@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

[@OlandoGaming]

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.

You are the one of the best Teachers in KZbin, 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

[@chrislombardi7134]

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

[@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✌️✌️✌️

[@merekhayaalsay]

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

[@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😅

[@LiveInTheMoment777]

this youtube channel is single handedly saving my math grade

[@Rhealmodiegi08]

Bro your a life saver

[@Programming-t8o]

Really amazing explanation 😊😊

[@arielbrinson8766]

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

[@vasitiwaku6336]

Just what I needed thankyou ❤

[@Sca_Ra]

is it just me because his voice is damn cool

[@mohit108414]

That was helpful. Thanks.

[@AceOfHearts001]

Very nice and useful. Thanks.

[@lonelystone1132]

dude be teaching better than IIT professors:))

[@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?

[@cesargarcia2310]

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

[@elbilala]

Am here for my tommorow maths test😂😂😂

[@kooljosh3511]

you’re goated

[@quinnpritchard8947]

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

[@SuperYoonHo]

ur awesome man

[@UmarFarooq-rn3wu]

Amazing boss

[@watchoutforcopyright9339]

what applications can we use involving domain and range?

[@zohairhussain8005]

Fourier series pls

[@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)?!?!

[@myanmar_songs_feeling]

Thanks sir

[@nanribetishaya4029]

Why did you change the direction of the inequality?

[@reverse5906]

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

[@blackheartjonsey1182]

What do u mean bro ? We need the g(x) to be in the domain of f but we don't give a shit about x to be in the domain of f because we are talking about f(g) not f(x)

[@k.p6582]

What about range puth?

[@tommymaguire7378]

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

[@AydenRiley-r9r]

Dawg you made me more confused get to the point

[@mohamedsaid8731]

Example one why you don’t expect-2 from the domain

[@sap2472]

Please do on eigenvalues and eigenfunction 😸, many thanks.

[@shorttricks3153]

But what about range 😢

[@sk8n854]

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

[@krest3900]

im cooked😭❌❗⁉

please help me cheat in a override exam 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏 I dont want to work to improve 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@budgielove17]

I love u

[@JJj-dr8fp]

why cant x be negative 2 😭😂

[@ulala9082]

PLEASE BE MY TEACHER

[@calesticall128]

You needed something value Power this here not building be energy in the body. Sorry I am sign in 😬🤗 dont hate me please

[@SamuelTewodros-l9j]

bro wtf is this English.

[@tomekk.1889]

The problem with these videos is they are too vague. There are no definitions, no examples of odd cases and meandering around the point without getting to it. Because of that after watching these videos people *kinda* understand what's going on bit if you gave them a hard problem to solve they would have no idea where to start because they have no base of knowledge. You ALWAYS start with the definition before going into example. Otherwise you have no idea what you're actually doing

[@Natalie-zn9im]

this makes no sense

[@abdulallahalharbi7825]

يحبي لتس بس ترا هذا Basic algebra الشخل جايك بعدين 😂

[@Elle-no9tf]

Early

[@Katty_kat-bf5vp]

tf I repeated it a hundred times already, still can’t get it. So dumb

[@ShelbyInman]

Oh my goodness, thank you so much for this!! I literally just learned this in my calc class today and I was so confused- thank you so very much you are a lifesaver 😭🥲
