Algebra - Quadratic Functions (Parabolas) 

You guys are complaining about how weird he is lmao it's more fun to sit through a class that has a fun teacher than trying to listen to someone who has a dead stone voice and is so serious... Aka my math teacher

This teacher has a great relationship with his students and is very patient. Very good job! Need more teachers like you.

I unequivocally love when the students ask "why". The quintessential question for learning and this teacher has shown the students that they can feel okay by not understanding a concept straight away. Brilliant. I love these videos.

This nigga held my hand till i made it to pre cal

very good teacher

I love how his students ask rudimentary questions, it helps me learn better

thank you sir, at the age of 57 and a sophomore in college, you my friend are quite entertaining and productive. Thanks again, thomas-

Thank you so much! My teacher sucks and he is rude and never explains anything and makes all the processes so complicated! I just came across your video and it cleared all my confusions, i am very weak at math and its very tough with a teacher like that... Your students are very lucky! Keep up the good work! :)

Those students were very lucky being taught by their cool and patient teacher! :/

The humor this guy has makes it to much easier to follow(: thank you do much.

Hey! I wanted to say Thank you so much! I'm in college algebra currently this Fall Semester and my teacher is really hard to learn from. She skips steps and doesn't explain what she's doing half the time. Most nights, I leave the classroom totally lost. But, since I've been watching your videos, I've gotten 96% on my first two tests. Thank you very much, I'd be literally failing without you and that can't happen when you're applying to the Nursing program. Thanks for doing this for us, you're honestly helping tons of people! :)

Wow learned this in 30 minutes. I wished that I had you as a teacher. You're so helpful. Thank you!

This man is BRILLIANT. I've tried to watch multiple teaching videos, but none of them really stuck. I love the energy that he brings, and that's EXACTLY what a student needs to develop. Every video I've watched is permanently with me now, and my confidence has skyrocketed. If I were selecting teachers for my school, I'd go out of my way to have a teacher like him in one of my classrooms. Superb teaching skills, top class.

always skip the textbook and just watch the video could have saved me a ton of time , THANK YOU

I rarely comment any youtube video. I like your teaching way.

Half the ppl commenting are what adults doing a refresher and bashing kids for trying to learn! I was taught the only dumb question is the one you don't ask... It's better to ask while in class than fail a test later!

After 40 years I can recognize a master teacher. I also view him as a "power teacher." I have said for years, "Plug it in." We were taught that statement in the 60s. He uses rewarding comments and no put-downs when they answer incorrectly. He also makes positive life comments as a sideline. It is nice that he has a positive and focused class. This is not a typical classroom. This was a new topic, and he talked about practicing at home. Great presentation and students understood.

You make math looks so easy, the world needs more teachers like you!

Just landed on this channel and video as I am enrolled in a college math class and have not taken any math classes in 4 years so your channel has been so helpful already! Thank you for sharing! Already making so much more sense after watching your videos! I wish my math teachers were as energetic, encouraging, helpful as you are!

These types of videos and math teachers are saving my ass in college! It's honestly inspiring. I have been watchinh videos like these for a decade and they always help me (as someone who is a visual learner and needs to hear questions answered clearly😊) Thank you. I have a quiz tommorow afternoon, I'm very excited.

Wow you are amazing dude, I was so confused when my teacher taught us this today. She made it so much more complicated that it had to be. I don't even think im going to pay attention in her math class anymore and instead im just going to come home and do my own notes on your videos. I wish i had you as a math teacher. So much better than mine, you wouldn't believe the shit she was making us do to get the vertex and the x/y intercepts. It was ludicrous, anyways thanks a lot man.

the students are too happy to be in math class -_-

In just the first 15 minutes of this video I learned more than I did in 2 hours of research via other RU-vid videos on this same topic. Thanks so much! The humor was definitely a key factor to me paying attention- without it, half the info wouldn't stick with me and I might have clicked away by now. Thanks again, and keep it up!!!

This helped so much!!! I like to think of positive parabolas as smiley faces and negative ones as not-so-smiley faces. Thanks a bunch!

Bruh he lit

Some of you guys are whack!! You complain when a teacher is boring, then when a teacher is funny you complain and say he is "corny" or "cringy". Smh, so sad.

I usually work with one student at a time. I don't know how you stay focused on the problem with a whole class asking a hundred different questions. Excellent job.

this guy is badass...if i had him as a teacher in highschool rest assured i wouldve scored high on the accuplacer! bypassing college math...

So much hate towards the students in the comments. If they didn't ask questions most people watching wouldn't of had understood some parts.

"That was the longest single problem I've ever done" lol she doesn't even know what's waiting for her in college sadly :(

I wish you was my teacher. You explain the problems clearly and have fun while doing it.

I learned how to do this in 5 minutes instead of sitting in math class for 60 minutes. WHOEVER INVENTED HOMESCHOOL IS A GENIUS

WOW. This guy rocks at teaching. He literally kept me entertained, and made those parabolas look like a piece of cake. He was able to explain the concept so well. Please keep up these videos!

This guy saved my life. My math was a complete wreck before I found his videos.

I totally wish my high school's math classes had had this kind of enthusiasm. I would have probably learned something then. As it is now, when I am planning to go back to school, and having to re-teach myself or completely learn from scratch how to do this kind of math, I am finding that watching these videos is super helpful and lessening my flight urge to run away from math (like I did in the past). These kids are super lucky to have such an entertaining teacher who is patient, informative, and willing to show how to solve this instead of just copying it from a book like the "teachers" I had in the past. Keep up the good work Teacher-man!

No one over the age of 40 should have to learn Algebra again. With that said, you helped me immensely!! I like that you put things in terms I never heard (or remember having heard) before.

I did your online quiz and got 100% thanks so much for teaching me how to do this! Now I can tutor my brother on it next week;D

What happened to the plant in math class? It grew square roots

The ultimate lecture. Its not every day that you come across a lecturer who keeps his/her class motivated denying them the opportunity to fall asleep. Good job.

I'm 41 and in my second year of college, a design school. meaning that math and I have never gotten along... so far, your videos have been THE BEST tool so far. THANK YOU SO MUC

✨I just wanted to say Thank You So Much for making these videos you helped me with so much!! I have so much trouble at school so this was the last thing I had to go to..... Thank You So Much again... Keep doing what you do these videos are very helpful!

I wish I could have you as my teacher! I was struggling with this so much and within minutes of watching this, it seems so easy!!! Thank you so much!!

Thanks bro, I'm absent for a week and my grades in algebra really suck so I need to keep up while I'm gone. Your lessons are way better than the one my teachers give. Very good job to you, my man.

thank you so much for being on RU-vid, I am in college for my BSN and find all of your math videos very helpful, my teacher just sits in front of the class and will not help anyone and gets mad if anyone does, the world needs more educators and role models like you

I have a horrible math teacher man.. i never had trouble with a math class or learning how to do math until i had her and I'm a easy kid to teach! I thought maybe it was me but the whole class and her other periods were complaining about her and then i realized she cant teach for sh*t. Thank you so much for making this video, because i dont think i ever wouldve been able to understand how to do this.

I love this teacher's pedagogic methods - he is a great teacher. In retrospect I feel sad classes at my university hardly allow any space for interaction. The professors always come out with the excuse "I don't have the time to answer all 300 students in-depth, so keep it short". I always have many questions but my professors told me to keep my mouth shut because I am 'slowing the class down'. Hooray for university, no? And when I ask them if I can speak to them after class hours they tell me they are 'too busy' and 'not available'. When I go to the student services and ask for help there, they tell me "we don't know any student groups that can help you", while there are at least four fraternities on my campus. I haven't bothered to contact the fraternities and I don't want to join them because most they do is being idiots. I had to shell out $2000 in private professor fees to pass some classes I had a very hard time understanding, thanks to my stupid university's elitist mentality. Discouraging asking questions is one of the main reasons I failed some courses at least three times in a row (but I passed them the fourth time after tremendous amounts of near-impossible effort). Anyway.. great video.

You should absolutely be my algebra teacher..you seem so fun and you actually helped me understand.THANKS!! :D

Respect for this guy for enjoying his job, and he somehow keeps things on track while fucking around at the same time.. He's like a mathgician..

Your math helped me a lot I gues I am not in trouble anymore

Your vids always helps I remeber more because you don't talk down.

in 2hours of math class (double period) i learnt half of what this guy just taught me in 30 minutes. Thanks so much!

People say RU-vid is bad for math help, then you have this guy.

Man, you are a good teacher. Explain steps good. Thank you. Nice to hear class enjoying themselves.

It's so cute that the students laugh at everything he says

I am in elementary school and my after-school program for advanced math did not explain how to do this. This video is very helpful!

I'm so glad teachers like you exist. God bless you.

Thank you so much this really helped I thought I would never learn this, I wish you were my teacher, you explain things very well

Great Teacher, wish my teacher was like this in high school, I would've actually paid attention lol.

I love this man… thank you for your help! I went back to school, my math exam is at the end of the month. Thank you for your help. Please, keep being yourself! ❤

you're the only maths teacher that i trust, you're really saving my life every day

Thanks so much this helped so much! This was honestly better than my teacher

This was actually really helpful, thank you.

We need such teachers here in kenya.The student are happy ever.

Never knew how much you would miss class laughter and funny teachers until it's takin away

Thank you so much!

You're a fantastic teacher.

the first time i fully understood from a math teacher on youtube, thank you so much

I admire your patience. To be honest, if I asked some the questions your students asked, I’d get yelled at or the “kids how come we don’t know this. You’re scaring me right now” speech that’s *supposed* addressing the *”entire class”* 🙄but was really just for me 😭

Video starts 2:30

Thank you so much! I understand now! Thank youuu! You're a fun teacher xD

Thanks so much I've put this off for two weeks, watched a metric crap-load of videos and couldn't master quadratic functions. Great Work !!!!!!!

As an algebra teacher who believes math ought to be fun, THANK you. I'm sharing this with my students next week. Also, it helps that I love Star Trek. :)

as cheesy as this guy is he explained it better than my 10th grade teacher

i better ace this quiz tomorrow

I was so stressed out about my math quiz until I watched this video. You made my day!!!!

Can everyone please stop calling these students stupid? It's rude and uncalled for. They are students. That means they are learning, just like the rest of us here.Now that that is out of the way, thank you very much for this video. I always have a very hard time paying attention during class and this grabbed my attention and was easy to understand.

Did you hear a war cry of a small child in the background at 29:18?

I hope I learn from this........ I HAVE FINALS TOMORROW and I don't know wth this is because I got confined in a hospital for a week and yes, I'm learning this by myself. Going to watch the video now...

God Bless, Thanks SO MUCH! I'm struggling so much in Algebra 1 due to my teacher not explaining things very well, even through questions. Every time we learn something new, I go home, go to "RU-vid," look for your videos on the subject (which seems you have everything!,) and learn a bit more through your videos! Once again, thanks so much, keep up the great math videos!

Thank you so much for your kind message.

how do you derive -b/2a

I was really understanding what the teacher says but when one of the students yell out I get lost on track and it's really fucking annoying lol

to add to all the comments, thanks for doing this. I'm struggling in algebra 2 as it is and my school just switched our teachers so now im even more lost and i have 2 weeks until finals. I understand absolutely nothing, but this video has helped get a better grasp on the concepts of parabolas. So again, thank you

bro you explain clearly to these kids with no hesitation, and when you go to the next step, they always ask how was the last step after you explained a few seconds ago.

if my teacher was fun like that i think i would do excellent

Can my teacher be like this instead of being so fucking serious everyday 😐

Your videos are beyond helpful, can't believe how no others come close. Thank you so much, this is saving me in college

wow! I didn't expect that by the end of watching this video, I would know graphing quadratic equations so easily! our teachers don't have as much enthusiasm as you! thanks, and keep up the good work.

hes one reason i will get an a in math semester exam

Good video. Annoying students.

my math teacher is not so thorough with her directions and this video really helps a lot. keep posting videos your a great teacher and you just saved my grade

Such a great teacher.omg . How i wish our math teacher is like that. He's nit corny at all. He's just trying to lighten up the atmosphere since the subject is freakin math☺️

R u from Star Trek

Uhhh that girl in the back is so annoying. She made the most stupidest statements!

What a nice guy.I hate math.I totally appreciate this man's enthusiasm for teaching. How inspiring!

Sometimes it's hard to ask professors questions without sounding stupid but his class would be easier to ask questions in! THANK YOU

I automatically graphed the problem when I saw it. It took me 55 seconds.

You've a strong friendly relationship with your students, I respect that, but I'm sure this video WAS MEANT to help out other kids such as me with math, but your students would yell out so I couldn't understand what you were saying, and I have to rely on the internet to help me with math because my teacher expects her WHOLE class to know everything when she talks with an accent and she speaks so fast, so accent + fast talking = -b/what in the hell did you just say?

I think this guy understood how boring math is and he made it more fun therefore more understandable, thanks

This is how math teachers need to be everywhere, unless you engage and have a laugh with the student, most of them will resent maths - a good teacher is everything.
