What are radians? Simply explained 

Even my school teachers couldnt explain it this well. Think this is the best explaination of radians all over the web :)

You deserve a pie for this.

I have never learned so much and laughed so hard at the same time. Good shit man.

This dude is the best. Why couldn't anyone teach it like this. I was struggling so much trying to memorize shit. Then I thought to myself, " If I just figure out how it's done I won't need to memorize anything!". Went online and found this genius. Thanks MrNystrom!!!

I have ADD and the sound effects this dude makes got me refocused and I was able to finally understand this. Thank you lol!

ok, I am literally falling asleep sitting here, I got like an hour total sleep last night from traveling and I still understood and comprehended this and am moving on with my work with ease. You're the man for real. I shared you on my social sites too, I hope you get a million views!

So dramatic lol.. But I get it now, thanks dude.

So that's why circumference is 2πR! Cause it's 2 semi-circles stacked together, each of which has a "length" of π radiuses! I'm 24 and I JUST got it. It was so fucking obvious! Why couldn't they just explain it this way?!

This is seriously one of my favorite math videos on youtube and I show it every unit that i introduce radians. NO ONE IS MORE EXCITED ABOUT RADIANS THAN YOU AND THANK YOU!

I finally got a clear concept of radians, pi, and the circumference of a circle after over a decade long Engineering career. I never realized that a radian is originated from the radius lol. Thanks for the wonderful explanation.

I'd love to drink beer and talk math with this dude! He's good people!!

10/10 would watch his beard again

I can't imagine having access to these types of RU-vid channels when I was in gradeschool and highschool :( I think I would have actually done well.

5:15 "If you see 2 pi over 3, you can cry about it or you can say 'well, that's just 2/3rds of pi radians.'" lol well damn.

I have been in school for YEARS, and this is the first time that I actually understand what a radian is :) Thanks for the dramatic explanation lol

Someone who actually wants to make things simple for students. Great explanation and energy. I wish all my teachers had this attitude.

Was learning this during the pandemic remotely and now radians and their relationship to degrees clicked. Thank you.

explained what 5 other people could not. thank you SOOOO much!!!!!!!!!!!

I love his personality. I’ve never seen someone so animated teaching math!!

Every year I teach unit circle, we MAKE SURE to watch the first while of this video. So good to hear a new voice, tone, and 'angle'. haha

After watching like 4 videos of what radians are I finally understood because of him! Thanks!

What a GREAAAATTTTTT VIDEO !!!!!!!! BEST EXPLANATION ON RU-vid !!!!!! KEEP UP THE GREAT WORK ....!!!

I think I'm in love. Seriously! Found his passion, sense of humour and knowledge completely attractive. Love the sound effects too.

MrNystrom, man this has got to be the best explanation of pi, radius and radians ever I went thru all of high school and didn't learn this or understand it. just memorized pi(3.14....). I think you deserve a noble prize!!!!

My professor recommended this video and I am so glad. This was fantastic. Thank you!

Thank you this was really helpful and one of the only interesting videos on radians out there to keep me awake!

A couple years ago I watched this video to help me understand what exactly radians were and this video helped me a ton. I'd like to take the time and thank you MrNystrom. You are a true warrior teacher cat.

I love him.... I have gone through high school precalculus, college calculus and algebra, and THIS is the first time someone has explained it, so I understand what it MEANS.... His enthusiasm is awesome, too!

This is actually much better than alot of the other videos! So fast, so simple! Great

By far the best explanation there is about radians on the internet.

Holy S**t. All the "easy" you tube vids I've watched to try and understand this and 2mins deep to your vid its clear as day. Your Sir are a legend

You are seriously my favorite. Not only is this informational but funny as hell.

Absolute legend, you emanate motivation and desire to teach, many teachers throughout my upbringing could not entitle me this, so I thank you for your commitment toward a broader, more inclusive scope of learning! Thank you my friend

you have no idea how much this helped. i actually want to cry.

I like how quickly you explained, it is painful watching a slow teacher sometimes. I generally respond well to logic, and this therefore beats memorizing the unit circle. Thank you

I teach at a high school in Morgantown, WV, and I showed my students this video today because radians weren't clicking for them (even though I explained it the same way you did), and they LOVED IT. They laughed and were entertained and best of all, the light bulbs went off. You might have to be a regular "guest speaker" for us when we get to stats!

This video not only explained what radians, but also pi. very helpful

my pre-cal/trig teacher showed this based on a students recommendation and everyone thought this was insane and hilarious but at the end everyone understood the concept so mission accomplished???

Probably the funniest and most educational video on youtube. Thanks!!!

Sir I understood you MASHA ALLAH! Your teaching method is too easy

Hey MrNystrom, I'm telling you.. freaking teachers can't explain simple stuff as that ! , great job man! , Hope you could make a video about sin cos tan....

Different people explain it differently. It's a good way of explaining

Amazing, a lot of things just clicked when I watched this video thank you for this valuable knowledge, I will cherish it for the rest of my life inshallah :)

Khan Academy need to learn from your style. I even watched and listened to you more so than the tall girl with the long black hair. Good job! Now I can explain it to my youngster... Many thanks for making something so dry worthy of listening to.

The 52 dislike are the kids who cried and didn't relax when they saw Radians

This is the best radian explanation video. Thank you and keep it up

Bro you just solved all my trig troubles. Thank you.

This was so helpful! Could you make a video on how to do more trig stuff?

I've seen many explanations of radians, but for some reason this video just made it so clear and precise as to what radians are (and where all those pesky fractional numbers came from). Thanks MrNystrom.

I went and explained all the members of my family about pi. lol. This is crazy. Thank you so much!!

I UNDERSTAND!!!! FINALLY!!!! Thank you so much... (my brain exploded a little bit)... You basically just saved my semester. You're the best thanks!

Thank you so much for explaining radians and the unit circle background information better than several professors.

This was the best explanation of radians!! Thank you!

This video was super helpful!! I started trig today and this is the part that threw me off the most!! My teacher nor the book didn't explained it nearly as well as you did. They just kind of "went through it" , so thank you man!!

You. Are. Brilliant. Thank you so much!

I have been studying about circles for half my life and NOW I understand pi. Mind=Blown. You did what all my math teachers couldn't. Thank you soooo much. :D

Even most textbooks don't have a simple and easy to understand definition of radians. This tutorial was awesome! (edit: subbed)

Brilliant!! If only all of my teachers at my high school were like you, Id be a much more intelligent man today!! because you make the subject INTERESTING!! well done.

I just taught this to my 11 year old...This video helped a lot and now my 11 year old is explaining this to his mom =)

Thank u so very much! I took trig a long time and forgot radians , this helps a lot , the enthusiasm helps a lot too. Keep making videos such as this .

Have no words rather than saying THANK YOU!

You give the best explanations of math & stats concepts

I'm so glad that my trig professor linked this video on the section for extra help with radians!

ALL SUBJECTS SHOULD BE TAUGHT THIS IS WAY, NO ONE FORGETS THE PIE AFTER WATCHING THIS. GREAT EXPLANATION.

Wow, way better than my foreign Trig teacher that I pay big $$$ for at College, thanks for actually making this easy to understand!

This is best video for explaining the concept of radians within the unit circle. I can't believe the concept was so simple, thanks man

YES!!!! You have no idea what a relief it was to see come across MrNystrom when googling "Radians". Strait up man, last year, when I had no idea what the deal with x bar and central limit theorm was, I watched your video, and I shit you not, I got 96% on that stats midterm. Now, I wouldn't be much of a stats student if I said that was causation haha, but I think you DEFINITELY were a part of that. Anyway, on to radians in order to hopefully not fail this linear algebra final...

I wish in my school days things were explained like this. Good job, sir. Thanks.

Best explanation of a radian ever.

This explanation set the missing radian in my mind circle! Good job, you are a really talented teacher!!!

Excellent explanation of what Pi and radians are. I was always told Pi was a constant but no one ever explained to me that it is the length of a the diameter of a circle around the circle itself and that radians are the radius (radii) of a circle around the circle itself. Not even when I watched the movie "Life of Pi" did I understand what were they all about...ahem. Get it? "Life of Pi?"

very energetic and very well explained

I love your energy, the concept is boring, but holy shit you made it interesting and easy, thank you

Thank you, this is brilliant. You are and incredible educator.

Awesome explanation of radians! Thank you!!

You're a legend bro. Explained in the way you think. I'll never not know what a radian is from this moment onwards. Look forward to watching you're other videos for some further brain explosions.

broke it down perfect!! finally i have an intuitive feel for the radian!!

omg I was laughing throughout the video 😂...but THIS IS THE ONLY VIDEO AND TEACHER that could explain this concept so easily.. thank you so much. immediately subscribed!

Thank you, don't stop making videos!

AAAAAHHHH NOBODY HAS EVER GOT ME SO HYPED FOR MATH!!! THANK YOU!!! And in all seriousness, thanks for the explanation, I needed this to be crystal clear for some web development I'm learning, and you made it so. Wish you kept making more content like this!

I love the enthusiasm and energy. I may be in high school but it's still a nice way to learn. You're awesome. Great explanations too.

Thank you! I got a distinction from your videos!

Explained very well. Kudos Sir!!!!

Thanks for the simple understandable explanation bro

I've been looking for a radian video to help me with my online geometry homework and this is by far the best one and helped me a lot, thank you so much

Good video. Simple and helpful explanation.

My math teacher really sucks at explaining things and this helped me soooo much. I wish u were my math teacher lol. Thanks

Can you get closer to the camera mate, hard to hear ya. Nah but in all seriousness, love this dudes way of explaining. HE JUST DROPS MATH FACTS RIGHT IN YO FACE. New favorite math tutor :)

This video has helped me immensely, thank you! I'm currently studying this for my Maths A-Level (England) and my teacher just could not explain what a radian is but the penny has finally dropped!

Best video I've watched on radians!!!!

6:52 "WHAT ARE RAD" lol Overall pretty helpful video Also very funny because of his word choicing

You are a genius. Thank you so much for the help!

Thank you so much! Very simple and entertaining!

The ghost of Billy Mays is really good at explaining stuff.

Thank you ive never had this much fun learning this

That’s really good explanation about Radians. Thank you for your energetic teaching. I finally got to understand what radians are 😀

hyper, intence and crazy math is my math XD also sexy beard math is my math aswell XD

So good. I didn’t want him to stop

You really explained this very well, thank you

I have been struggling with this concept for almost 2 years now this is the first time I’ve understood it thank you so much now I won’t fail my algebra II exam
