Because he is a good teacher, he explains clearly without mysteries and everything under control and somewhat friendly circumstances that's why HE is the best teacher online.
It wouldn't be crazy to think that a tutorial from a good mathematician 100 years ago would be much more helpful than one from a mediocre mathematician now, imo.
Agreed. Math is a truth that will stay the same through the ages. C/d will always be 3.1415926535897... for example, even if we decide for whatever reason to call C/d something other than pi all of a sudden
lovin how he starts w/ a little review and then goes through everything else slowly and patiently. "Someone was calling me, but you're more important": A+ teaching right there.
"It's pretty sad. I'm showing you how to do derivatives in calculus but I don't know how to erase faster..." I was watching this in my lab with my headphones on. I was laughing so much that people started looking at me. Anyhow, this is the best video. Thank you so much
What kind of lab were you in where your instructor let you sit around slacking off and watching RU-vid videos lol?! If my O-chem teacher caught me pulling that shit I genuinely think she'd give me a smack!
You taught me more about derivatives in shorts nine-minute increments than my awful teacher did all summer. Math is not fun for me and you made it SO much easier. Dear god thank you.
Its those little steps you show that help us understand how to work the problems... Hopefully PROFESSORS IN UNI can find this comment and take note. Dont skip the small steps please. You might not need it but it helps those who do. Saves us and yourself some time from having to go back in the lesson just to reexplain everything. 👍 UCF! UCF!
Obama gets the Nobel Peace Prize and this guy doesn't? You are the man Sal! I can't tell you how many late nights we have spent together studying Calc and Chem! Keep doing what you are doing, everyone appreciates it :)
Did you hear that?? Phone rang and he said we were more important !! This guy is a fabulous teacher, amazingly so. Thank You for all your time and effort. Thanks to you I'm sure there are now kids out there who now won't choose a major based on how little math is in the curriculum.
“I feel like a real teacher” has taught me all the way! Thanks Sal Khan, the world would be better if we could raise your existence number to the fifth power
leaving the video with the portion of just trying to erase the board was genuinely amazing. It's like an artifact from a time where everything wasn't expected to be instant and polished up 100%. You showed us the parts that weren't so glamourous, and I appreciate that a lot
like I have been learning this for ages and I feel like the only one in my class not to get it and now I feel like it's so simple. I should have done this ages ago, thanks Mr Khan
This has been mind boggling! I was good at calculus but entirely forgot (or never learned) these foundations. Watching from the beginning of this series to here, I understand derivatives in a way I will never forget and it is all completely intuitive. Amazing!
I am pursuing my master's degree in systems and control engineering, which you may already know involves tons of math.. I'm currently struggling with my thesis project, and I'm too lazy to open my undergrad calculus book . So I watched your videos about chain rule and product rule, and it has tremendously impacted the progress of my thesis project.. Thanks a lot Sal! From the bottom of my heart. Bless you.
Im teaching myself Calculus before i graduate high school. and with these videos its so far a much easier process than taking a class or learning out of a book. im not sure i could accomplish my goal of teaching myself Calculus and applying it to my AP Physics class and Physics in general without these videos. Thanks a million!!
I've been watching your videos for years now in all sorts of subjects and I'm still awestruck by how amazing they are! The way you teach concepts just makes them click.
thank you for making this information easy and public. My professor has a very heavy accent and leads to a difficult environment to learn abstract concepts. This has helped me so much.
I took like 3 lectures(around 2 hr and a half) and consultation period yet I failed to understand what the heck is going on, turns out all I need is a video that’s not even like 1/10 of the time I spent. Thx for such! You are saving my life!
Sir loved it when u said u r more important than my phone call. Let me say this "The way u teach helps me cover everything with the intuition and concept that makes me learn realistically". My school, college seems to me a business hub where making money is more important.
One of the main reasons I like listening to Sal instead of my teacher is because he seems so humble. He always says things like "I really hope I haven't confused you", and I just feel like I'm listening to a friend talk. I'm less intimidated by him, haha.
Oh wow, this is great. My Calc BC teacher is the worst, doesn't teach anything and still gives really hard tests. Thanks, this has been so extremely helpful.
Thank you soooooo much you're the only reason i understand calc I wish my math professor was half as good as you at teaching. you just gained a subscriber. many thanks and compliments
It's like you can read my mind! I found it to be a tad confusing but you explained it really well so I didn't get completely lost in what you were saying. Great teacher here!
You are SUCH a good teacher!! the first example you did I was like "hmm I dont relaly get that," But after the second one I was like "OHHHHHHHH!" its insane thank you so much Sal
I like how in the first video he states how he needs to get a new program for his videos yet he uses it for like twenty more xD. Well anyway these are some of the best videos ive seen for calculus. My math teacher isn't flowing with how i learn and he's moving really fast. These videos click with me though. Can't wait to keep on learning!
in every subject by the way! my orgo exams wouldn't be the same without your videos. I literally went up by about 40 points in my orgo exam after watching your video. Calc will be next ! thanks
Haha I love it "I'm teaching you derivatives, but I don't know a faster way to erase than this." Thanks for being wayyyy more helpful than my real teacher!!
You make your videos feel easier for people to understand, and for me, your one of my greatest math teachers ever!!!!!!!!!!!!! Keep up the awesome and great work, SALMAN KHAN ( |SAL| ) d:D
Great lecture, the same as many others, this teaches way better than my maths teacher did. I'm just going over high school calculus now, starting up university level maths and you are DEFINITELY helping :)
