Just wanted to let you know that pretty much solely bc of these videos I just got a 94% on my first calculus exam, the class average was 57%…

I swear your channel is a gift from the universe. I'm last-minute studying for my math final (that's in two days) and your channel is a huge help. Thank you for all your dedication to the material you teach! It's super easy to understand and follow along.

Your voice is like asmr. So soothing, probably listen you for hours.

[juliacostello]

Just want to say you are the best online tutor system out there... for years now I have only been going to your channel. Thank you for all the help and keep it up!!! :)

Love your videos! I think it would be beneficial if you made a separate playlist for each chapter, like one for functions with all videos appearing in order in which they should be studied.

I gotta thank you so much, thanks to you I'm not failing classes

[whatidoknow]

You're like a hack to calculus class. this was really great. Like you make exam questions look so easy

[yes]

ur the best i got an A+ in pre-calculus because of ur vids

[manahelh.]

The fact that hes is making me understand a year in one video is crazy to me

[okuu_utsuho]

Before, my functions aren’t functioning. With this video, my functions are now functioning.

[yasirtaher]

I recently looked at your videos and they seem to explain everything clearly to me thanks keep up the good work

MR. Organic Chemistry Tutor, thank you for an outstanding video/lecture on Functions in Algebra. Functions are the heart and soul of Mathematics. Functions are very important in Mathematics, Physics and Engineering Science. An example of a function in real life is a vending machine

[faheemalvi]

love you so much sir, the method of teaching is very well. Allah blesses you!!

[foziljonnosir]

Hello, I am going to start learning Functions from 0, from which playlist should I start, please give me advice. The thing we are learning at school now is Liberal math.

[tensionshift]

Thanks man, you are a literal lifesaver

first video in the playlist. abt to go through every video. 1/226

[Simon-cwll]

for the problem at 7:54 (are f(x) and g(x) inverses of each other. Could we not just figure out the inverse of one of the functions and then compare to the other.
for example f(x) = sqrt(3x+1)
find inverse = f-1(x) = (1/3)(x^2 -1) which is the same a g(x) therefore they are inverses of each other.
Am I thinking about this correct?
thanks

[ibemereaugusta]

your videos are so good, very clear and understandable...

[leylarzayeva]

I have a final exam tmrw and its like rlly important cz next year im going to highschool, and i gotta thank you for such a great explanation of this hard topic. <3

[dr.mutlucelikkol]

The videos are great ! thank you so much, but there is serious problem in the arrangement. Since the videos are NOT numbered, when you have downloaded them as a playlist altogether, they are automatically arranged alphabetically :-) which cause you a very boring job of re-arranging them according to the subject !
