I'm not trying to sell your ego, but if I had math teachers in high school explaining these concepts as you do i would have had at least a Master's degree in mathematics years ago. I look forward to more of your videos.

I'm 68 and am trying to teach myself quantum mechanics. I am currently reading Schrodinger Equation book and I am so grateful for these videos with this teacher. He is brilliant at explaining things slowly and yet in depth. Can't thank him enough.

This is a teacher. The sincerity and the wanting of the students to know and understand is really appreciated.

This Prof is a genius, I can't find words to describe his teaching skills. He has really demystified this topic. Bam

You got 5 stars for your knowledge and ability to explain in a way that a dummy like me can easily understand. Thank you Sir.

I am brushing up on my maths and physics to help my teenage grandson and I'm really getting into your videos as much for my own satisfaction. I wish that you had been my physics tutor at college 58 years ago when I was studying electrical engineering. I hope to watch all your lessons - most satisfying and enjoyable, thanks.

Many people have learning disabilities and different learning skills. My 9th grade pre-algebra teacher made me sit on a stool with a (DUNCE) cap in front of my class! Ever since then, math was worse than any plague!!! You are one of two video tutors that gave me the confidence and determination to challenge mathematics head-on. Class of 2022!!!

In a matter of minutes, you make what functions are have meaning and reason. When you have the logic of it, you can further understand the practical application , and this is coming from a 67 yo man. You're teaching, is really at another level. Thank-you.

This guy just taught me what my teacher could not in 3 months

I'm studying for my finals and this is literally saving me! Thank you!

please sir don't stop teaching and making videos like this. You are very intelligent person. I have never seen a teacher like you before !!! THANKS a lot!!!!!!!!!!!!!!!!

hey, to anyone who feels hopeless rn, im in college calculus and my dumbass doesn't have the fundamentals down, so im here at 1 am. Im not worried, im just learning. If im out here doing this, you're already doing better than me and should relax and keep on learning haha

Wow what a maths teacher. I am 68 and doing these maths videos for intellectual stimulation and revision of school day maths. If I had had a teacher like you teaching me maths I would have been ace. You make maths less daunting and so easy to understand I will definitely be recommending your courses.

Taking function more than 40 years ago, never remembered that it was so easy to understand. Wish I had a professor like you.

Thanks a lot. I'm 39 and still curious with math subjects that I learned over two decades ago. I even bought some math books for high schools, but none of them contains clear explanation like yours.

This professor doesn't just know his math but knows how to teach it. Thank you!

Thanks God for KZfaq and this awesome teacher!!i don’t think I need to go to my classes anymore....👏👏👏👏

I have never encountered a good tutor as this man. Now am sure am clearing mathematical analysis this semester. Thanks Sir.

my teacher was to lazy to teach us this so she gave us this video. Byfar better than anything she would have done. Amazing lesson man!

What a wonderful teacher! I needed a refresher so as to help my grandson with his math later today. This presentation did the job PERFECTLY!!!

Wow! Finally a lesson that brings this subject 'down to earth'! I can't thank you enough!

This is what i call an amazing teacher

Finally, I clearly understand the terminology you explained perfectly, thank you, Jason, for making life easier.

Omg you have lessons for everything; electricity, science, math. Wow your a genius.

Thanks! Back in the 80's I made my way through Math, PreAlgebra, Algebra 1, Algebra 2, Advanced Algebra, Geometry, Trigonometry, Circuit Analysis, Transistor Analysis, etc in the evenings at the local Junior College for about 4 years with a 4.0 GPA. Life & Family soon became my Priority and I never got into Calculus. So, I figured I did pretty good thus far...how hard could it be? Ha...Calculus is Humbling! Especially if your on your own. Everything always started off with "Function of X"...WTF is that!? Why do they always start off like you already know what that is? Now I know and feel like I can now move forwards :) Your Explanation of the various "Functions of X" is well done and quite Informative too!!!

This is one very fine teacher. One thing that students respond to is the enthusiasm and energy of the instructor for the subject. WOW! How could you NOT get into this lesson, given the excellent teaching and enthusiasm of it's presentation? GREAT JOB!!!

Seriously the best explanations! Thanks!

honestly he taught me more then any other teacher has ever try on teaching me. Thank You!

this is literally the best explanation

I had a Russian teacher who did not care to take the time to explain this technique as you did, and my class could not understand through her thick Russian Accent, omg I wish I could have had you as a teacher to explain to us. It would have made a big difference. Now that I understand your concept it makes understanding this so easy. thank you so much Math Science. Your the greatest and you broke this down to us

The best explanation ever I've came across.Even my Math Teacher can't explain clearly like this.

You saved my life before my exam thank you

I'm 26 and I feel like I just discovered maths, fun stuff

I’m speaking to the teacher. Sir the way you teach is awesome if you keep on teaching this way in all of your videos I predict that you’re going to become a very rich man because there’s a lot of people out here that need your type of teaching. We need you sir please don’t stop giving us these awesome videos. I am 57 years old and I’m just starting my undergraduate degree and you can imagine how challenging it must be for me at this age to attempt this but you have given me a light at the end of the tunnel because I knew that I had to have a strong foundation in mathematics and by learning from you I will be able to achieve my goal thank you sir. Sincerely Nicanol Collazo

just wanted to drop a note in here to recognize this man. you clearly put in a most sincere effort to explain and be thorough, and your dedication to covering all these topics with all of your videos, is working for me, helping me understand what I need to learn. But just as good approach, as well as thoroughness, is good enough, you have put on display a goodness that humans can have. to do a good job teaching and to help people and contribute to the good of others. good job well done on all of your many many videos, I've watched many now

You made me fall in love with calculus, you're amazing keep enlightening us 👌🙏😆

Honesty I watch many video of this ,and this is the first time I understand it ,thank you much ,I have exam of it the 9 of this month ,so many thanks

I have 8 years of software development experience and last time I learnt functions was 12 years ago. This Professor has just reprogmmed by brain. Huge Respect.

Iam studying for my GED and almost gave up on this topic, until I saw this video . Just saved me.Thank you for teaching step by step. May God bless you .

My gf didn’t understand this, so I found the easiest way for her to understand, thank you.

watching this the night before my exam. thank you #legend

i think this is saving my skin,, got a maths tests tomorrow, and the teacher didnt explain any of this. he said, and i quote, 'do the curve thing'. never explained it, just told us to do it. bonus points because i just had 2 weeks off, asked for work so i wasnt behind, and didnt get any of it

There is only one word through which I can describe him, GENIUS.

May Allah Bless you, This concept was very difficult for me to learn but you are actually trying to teach people and not overcomplicating it as well thank you.

Because of your instruction, I am able to understand many math concepts that have had me flummoxed my entire life. Your explanations and diagrams have opened up a difficult subject for me. For the first time in my life I am enjoying math. Yes, I am enjoying it!!! My sincerest thanks to you, Dr Math and Science! ❤️🌻♥️

Sir I'm so grateful for your videos . I'm appearing for competitive exams in India where this chapter is very important. However being from medical background I couldn't understand it. After watching almost 10 videos I reached here and I've never been the luckiest. Thank you so much .

Absolute legend! Thanks for this, you've made mathematic functions easy to understand!

thanks i really learned something today thank you so much i have a really tough time in math and when i watch your videos i can understand it I will be watching more for more math help and it helps because i have ADHD and it grabs my atention and makes me focus i wish i had you as my teacher

My Name is Sam T.saylay am from west Africa Liberia. This Prof have taken away the fear of me reading mathematic at university and I want to say May God give you a longevity of life.

I've spent over 2 hours trying to understand all this & you just made me instantly get it in 10 mins. Thank you!

Im 65 and thought I was too stupid to learn anything math but I see it is completely understandable. I feel robbed by all those teachers who didn’t teach this subject well.

I wish you existed 60 years ago to enjoy my mathematics then before graduating as an engineer

This is the only video that ive seen that actually helped me to understand functions, this man explains everything so simply

The only Prof that made me grasp math after watching a lot of math videos the past 10 years, THANK YOU!

Thank you so much. I am beginning to understand functions a little bit better.

Honestly this teaching is so clear and made it easy to understand. he really wants us to understand every single things here, . Even a nerd like me understood him. I'm in middle of this video lesson and i couldn't stop myself from admiring his truly passionate teaching. Thank you. God bless you....

I want to give you a high 5. You are an outstanding teacher. You just cleared up 20 years of misunderstandings about functions for me

you are the best teacher I have ever seen, good work.

Great video, I'm watching in my time off so I can keep my mind sharp.

Hey professor first of all I would like to say ur teaching skill is perfect I liked it very much and my opinion is it would be better if u make a live so that we can ask a question and u will answer as too and I like how u reply for students👏👍

I have been taught in my college Algebra class and watched a dozen videos on this but I Love the way YOU explain this! Thank you , thank you so much! I Immediately bought your online program.

I’m so glad I stumbled onto this video….his explanation is amazingly easy to understand. Functions are fascinating

Awesome way of teaching. A Perfect complete guide

Thank you for the Great Video. Could you kindly share the title of the next video? I want to watch all your videos about Functions in the right sequence. Thanks again for the excellent explanation. 🙏🏻👏👍

Thank you so much! I asked my high school teacher what is a function. We were doing functional exuations but I had no idea what they are. She couldn't explain. After 10 mins of whatching this I understand it. When you drew the graph of function f(x) = x^3 I instantly got it why is it like that. Before I had no idea what those graphs represent.

I struggle to sleep, but 5 minutes of my maths class will send me straight to sleep. But this guy....Kept me awake and helped me ACED MY TEST! Please keep the videos coming, you are a great teacher.

this man has to be the best. i love ur way of explaining. your lesson is amazinggggggggg

I needed this for my assessment thank you soon much I love you for this

Excellent teachers are a rare breed and he definitely belongs

This may sound trivial or hair-splitting, but I'd prefer to hear, "A function is a machine that USES values of x to generate y." I think students will relate to that quicker than most other phraseology. In other words, plug in a value of x and the function spits out a value of y. You did a good job. It was lots better than Mr. Bloom the freak who pretended to teach us Calculus 101 & 102 did.

Me in 12th grade finally understanding 8th grade maths.

I have to studying this in turkish idk why im here but that just made me understood everything. Woah amazing 🤷🏻‍♀️🤷🏻‍♀️😶

Beautiful human being! Thank you!

All the way from Kenya...thanks so much I understood

Im 13 and just into pyhsics but i need to learn math, then i started to learn math and now i love math more

Wow this easy. Thank you Mr 💖

I did my Cambridge"O" level in 1967 and I was best in mathematics but I don't remember learning function then. Perhaps it was not in syllabus then but I don't think I would understand the subject unless you were the teacher to it.I am now grasping avery thing on this lesson my age (76) notwithstanding and enjoying the whole program.Thank you very much. I am still following maths lessons just for the love of it

Yes! As Nadia Ahinkora said, demystifying. Thank you so much.

Thank you very much sir that's all I can say because what ever I say it's not going to be enough

Why can't you write a book ? Your explanation is so really

You are definitely the best in explaining things. I have no words to describe your teaching skills.

This professor is a genius, and I am at a loss for words for describing his teaching abilities. He did a fantastic job of discussing this subject. If I had this teacher, I wouldn't ever dislike math.but it never gets late. I'm really thankful.

You're amazing... Keep up the good work.

I have been trying to Teach myself Calculus for several years and until now I just could not get my head around "The Function" until now!

omg thank you so much i just finished 5th grade and i am hyper accelerating to 8th grade math and i was having so much trouble on functions and the test is in 2 days but this helped so much thank youuuuu!!!!!

The best teacher here🎉

Im in 5th grade and im this and i see high schoolers here thanks allot this really help me have a nice day!

Thank you so much for this video, I am studying for my midterms and this helped me a lot, thanks!!!

its awesome. i always confuse on funtions so mostly skip theim but the way you teaches us its very amaizing i actually wonna be a teacher like you . whole of concept is printed in my mind repectively . thanks again for teaching in this depth.....................

You made it look easy to learn function. You walk me through without being lost. Great guidance

Professor what's is your address please, I need to be keeping in touch with you,you are really amazing teacher.. I am all the way from Masinde muliro university, Kenya I appreciate your teaching

Thank you, professor. This helped me a lot.

Thank you. That was so easy to understand. My maths confidence has just shot up . Again, thank you very much.

For some strange reason I have struggled to understand functions and finally I can say I have understood thanks to this excellent teacher

I need to know, how we examine relation in a quadratic equation

I’m In eight grade and I’m learning this imagine what is gonna happen to the kid in the future

This is too clear, like a spotless ocean that directly reflects what I exactly need to get. This precisely represents the perfect reviewer if you forgot why that certain function looks like that in the graph. Very much appreciated! Thank you.

I think the reason this topic is tough is because we don’t have a good explanation or overview of what it is and some different ways we might see it. In fact I think all of math is like that, How many of you can recall doing the textbook problems and then you get the homework and can’t figure out how to do a problem because it looks different in some way? It’s because we aren’t taught to know, we are often just taught to memorize. Math is so much more enjoyable in my experience if I have concepts broken down like this. Great job!

Thank you! l get it

im curious, what age do your schools teach you this stuff?
