I just noticed this. Youtubers are really good at explaining lessons because there is a "necessity" to do so. If they suck, no one will watch them and they gain no incentive. Unlike your school teachers, they are already "paid", so whether they give their best every lesson is, well, basically an option. Plus teachers are humans, they get tired from teaching all day, which decreases their performances.

But of course, there are really good school teachers out there.

God bless you for this. i was literally in tears yesterday when i got to class and was the only one who didn't understand

It’s nice to see that people share the common problem that they have professors that don’t explain things well. My lecture in precalculus is almost 2 hours and I end up leaving more confused than coming in. And I’m going back to school after 9 years. I really was about to give up after flunking my first test but I found these videos and I can’t believe how simple you put things into perspective. My professor teaches us as if this is as easy for us as it is for him. Thank you so much and good luck to everyone else out there kicking butt in school!

I'm 16 grade 11 in India and I usually go for videos in my native language but oh my my.. your explanations are so clear that language is not a botheration anymore.. subscribed 👍

My professor teaches like we have a PhD in mathematics in my pre-calculus class. You should see me in class I'm like a philosopher just questioning the meaning of life. What has life become lol

[arianepalaruan]

Do you know how happy I feel? Do you know how much I"ve improved by now? Everything is thanks to you, you're the best teacher I never had. I hope I can mail you some thank you stuff!!! THANK YOU SO MUCH!!!! I LOVE THE WAY YOU TEACH!!

[venusrishi]

The best explanation of this topic ever. I am a university student who has been struggling to understand this topic since school, and you made years of struggle go away in 18 minutes. Also, to everyone writing an exam, YOU GOT THIS <3

[loserface]

im learning more from youtube videos than my professor smh

[alexgavrilchik]

How come my teacher gotta take a whole 50 minutes and still unclear, and this dude explained it perfectly and to the point in under 20 minutes.

[mattym]

y’all talkin bout how you guys are learning this in college, i’m in 8th grade why tf are they teaching me this

[javiergiraldez]

Remembering my University years back in 1984. With this type of explaining, we could passed those exams way more easy. Excellent my friend

[baraaabusabeeb]

I feel like I am studying in the “YouTube college “ frr

[colecoppess]

This is the absolute best math video I have ever seen. It gets straight to the point and not only tells me what I need to know, but teaches it thorough yet concisely.

I love that you cover so many different kinds of examples in your videos, not just easy or simple ones. Not too many others are doing that. That tend to want to stick to the basics or keep it simple for us when the problems we are having to solve are more complex than that and require that we understand all the rules - not just the basic ones. THANK YOU!

People who are watching this video fully, are you guys getting that "high" like me? You know, when you finally "get" something and immediately the satisfaction makes you feel so good and suddenly very confident that you'll be able to solve questions like these... oh gosh, my serotonin levels just shot up.

[upscalien]

Hours of reading slides, going to lectures and reading textbooks yet it only took your video for this concept to click in my brain. I'm ecstatic. Thanks to you I can get a little bit more sleep tonight :)

[leedaniel]

I have struggled with this topic for a very very long time.. I cannot even begin to explain how thankful I am.. Thank G-d for you.. You should do video on domain and range for trig functions, that be great..

[AsadKozibaev]

this dude explained everything I need in less than 20 mins, which my professor couldn't in whole semester

[lostdreamerofthestars]

This is really helpful now that we're self-studying

[meaganireland]

This is amazing... I get so frustrated with textbooks that briefly explain one example without covering or explaining "why". You did a great job breaking it down in a way that makes sense. I find that knowing the "why" behind things makes it so much easier to comprehend. Thank you so much for this
