- sorry for a little confusion, i am very tired today but hopefully it'll make enough sense for everyone and also see these patterns. I thought it was amazing how fast i memorized this so i wanted to share my knowledge with everyone and hopefully you can memorize it just as quick!! my first video as well :P
You just made me memorize this thing in 12 min when my teacher spent like 60 minutes going over it and I retained barely anything
You're lucky... My pre calculus college professor didn't even show us this... I'm kinda pissed
@@Blighted_Ashes
Yeah same bruh they were supposed to teach this in 10th grade but didn’t
I got stuck on a problem where tan theta was -1 so what’s theta so I had to look this up
FUCK SCHOOL FUCK SCHOOL FUCK SCHOOL FUCK SCHOOL FUCK SCHOOL FUCK SCHOOL FUCK SCHOOL FUCK SCHOOL
@@markrutte5637 its ok bro you got this
@@Blighted_Ashes YALL TAKING THIS IN COLLEGE??? i can only imagine how much more advanced its gonna get for me cuz my ass is learning this at 17😭
THANK YOU! THANK GOD YOUR DAD DIDN'T PULL OUT! YOU SAVED ME
Best comment ever
well for me i wish my dad pull out
Started off good, then the comment got weird real fast.
What does this fuckin loser think he's funny or something or original or something what hey woo now
I CANNOT BREATHE
Never thought a 12 year old video would be my savior, thank youu i understood none of that before now
dam this was 7 years ago...your video is still helping in 2019
Sena L in 2020, also haha
@@sarahguerrero7792 yeah lol
no sh!t.. math doesnt die or get old... most people have to learn trig at some point in their lives
Fucking correct .. hope it continues to help further
September 2020
5days i go to 7 - 11 ... that was gold
Helps me remember it easily :)
Another way to do it is.. Times 2 minus 1. Example 3*2-1 = 5 so it's 5pi/2
Ivan Kougoucheff that’s how I remembered it too
gokuuuuuu~
Popeye's and 7-11
9:43 You hear me yell 270 across the quantum flux
same lmao. My jaw dropped when I saw that.
You've taught me the unit circle better than my Pre-Calc teacher has done in a month. I have a test tomorrow and I know I'll get 100%. Thank you.
How did it go
@@isragashi11 100%. Thanks for asking, mate! Finished Pre-Calc with a B-, and I'm thankful for that.
@@Potato-yd3hv I'm glad to hear that!
@@isragashi11 Just about to ask the same thing hahaha
@@Potato-yd3hv Nice! I'm doing pre calc this year and it's a struggle. My teacher is giving us lessons on the basis of the students already "knowing" the information needed to support the new stuff being taught. I'm barely scraping by with a low B right now.
You are a real teacher, please go help students in high school and the community colleges. You were born to teach; please do it for humanity.
Robert M St Fleur just because she knows the unit circle doesn’t mean she can teach community college lol
Abraham Liftsheavy does a better job than my teacher does sometimes
saw di pa fe sans fre, nenpot ka revele yon sekre
@@kensyjolicoeur ki sa w'ap di
@@abrahamliftsheavy8933 Dunno man, she tought it better than most of my teachers have in 2 days of review.
Usually, people look crazy when they write in all caps, so please bear with me. THIS WAS THE SINGLE BEST EXPLANATION OF THE UNIT CIRCLE THAT I HAVE EVER SEEN! I have gone to a lot of trouble to learn how to do this, but always get tripped up on the radians. The way this girl broke it down made it all come together. I have seen people go a whole semester and not know how to do this, but she kilt (not killed) this in minutes! SHE KILT IT! And did you catch it at the end when she said this was her FIRST video? For the love of God, please do something for the rest of calculus and trig! Sorry to be greedy, but it's your own fault for being so good.
HAHAHA
for the bottom right you can just multiply by 2 then minus 1
hi
omg THANK YOU
Pro4banned you have no idea how many lives you have saved with this comment
Wow, thanks!!!
Thank youuuuu
It actually took me 12 min and 46 seconds to memorize it
Do it at 2x speed pleb
which is in minutes
This was godsend. Never has an 11 year old video been so useful. Thank you so much!
don't forget to add 2pi at 360:0, pi/2 at 90, pi at 180, and 3pi/2 at 270 everyone! In case people were getting tested on this, but still good vid nonetheless!
i was just about to comment this haha
Thank you so much i completely forgot about these
THIS IS THE MOST HELPFUL VIDEO I'VE EVER WATCHED THANK YOU SO MUCH!
now you are very big on youtube great job hope your career goes good
Thank you :)

@@vipergurl89 girl thank you so much
@@mechagear4819 lmao i just saw xD
This is a life saver. I’m in 12th grade and in precalculus with a very fast-going teacher. We’re starting out Intro to Trig a week ago, I was out sick for that whole week and couldn’t contain any info on how to do it. I come back a week later, it’s Thursday now, and I’m guessing we’re having a test pretty soon, especially since midterms are in a week as well. Long story short this video has saved my ass. I got it within 2 mins and 34 secs of the video and I’m thankful. Bless your soul.
Same situation with me lol
EXACTLY MY SITUATION RIGHT NOW i've also been sick for the past week and man even though it's been like 4 days she's already almost done the entire unit. now I'm just trying to teach myself everything lol
My english is not good but ... to memorise 4°quandrant you simply add the top and the bottom from the opposite side (2°quadrant).
Example:
2π/3 (2+3)=5
3π/4 (3+4)=7
5π/6 (5+6)=11
Hope it helped ☺
Ps: it also works with 1st and 3rd quadrant
@@carinax3131 not really yet?
thank you!
also multiple it x2-1
thxs man, that was very help ful. I only needed help memorizing the top pies for Q2-Q4, and the (x,y). you both truly helped alot.
I dont understand why teachers dont spend more time on the unit circle like this!!! Its such a fundamental concept and they just throw it at you like "here know this". Thank you so much. This makes everything much more clear!!
i have my math final tomorrow this saved my life
now 29 02 2015. tomorrow me also.
+Sarin Chea me too.
+Mazthor 2.0 wish u good luck. ur age?
16
+Mazthor 2.0 you are boy or girl?
This literally helped me to memorize this within 10 minutes. When it took me an hour in class to even understand what I was doing. As soon as I watched this video, I completed it within 3 minutes.
I have a test in 20 mins let’s GOOOOOOO!!!!! This is so helpful btw.
Anapaula Rios ayyyyy that’s me 6months after you posted this LETS GOOOOO
Did you pass
Blighted Ashes I did! I still remember most of this too :)
@@anapaularios3888 that's good! I unfortunately am hung up on trig equations... Ugh...
@@Blighted_Ashes hope everything went alright!
This was tbh the best explanation for unit circle
Thanks alot :)
*it was better than my teacher's boring lecture*
Keep it up
Girl... Ma'am... Lady... Woman.... YOU ARE FREAKING AWESOME!
This was seriously helpful, even 12 years later!
this is published six years ago and its still the only unit circle memorizing video that has ever helped me, THANK YOU
Amazing how a video from 2012 is still so relevant and helpful in 2019.
Simon Fetuu yes math is always relevant
and in 2022 :)
2020 we still learning this shit and she’s still helping 🥰
2021 going strong
Holy crap, I never understood why When I tutor younger kids they in understand it so quickly but can't get it in class. It's because your a kid explaining it how a kid understands it. Your such a savior 🙏
been struggling all my life to understand this thing from so many different sources and here this girl has blown my mind in 12 minutes. GOOD WORK!!
you saved my life !!!!!!! Our teacher is making us take a quiz on this and only 5 mins
Same
Alex King what make you think I came here lol. because I have a quiz on this Monday. xD
we have 2 min and we have to answer questions about it without drawing it
YOU ROCK! I have been struggling to memorize this, I watched your video ONCE and I went and drew up my own unit circle and BAM just like that memorized. Thank you so much for you help, keep inspiring other students!! ~Sam
I can not verbally describe how incredible this video is bro, thanks so much! its 1 am before my test thank you!!!
This is by far the most helpful/easiest way to memorize the unit circle that I've ever seen. Thank you!
You deserve some kind of prize for this. You've made studying for my exam about 1000 times easier AND YOU USED RADIANS THANK GOD.
5, 7, and 11.
They are all the prime numbers after 3.
They are also twice the denominator minus one
they are also odd numbers what you wrote wasn't helpful at all
Carvel Peele Yes it was. It could be helpful as a memory mnemonic. I know the primes after 3, the fourth quadrant is after the third quadrant. Helpful.
Connor Skudlarekwhat I am saying is that you can find many ways to relate those three numbers to each other, and yours was helpful I admit but its not special just one in a million
+Carvel Peele I didn't say it was the only method. I just suggested one, pretty easy one. :)
I literally have a test on this tmr and this saved me lmao... 12 yrs later and your video is so helpful :)
over a decade later and you are still saving us! Thanks for the help!
Watched this video and was literally able to recreate the unit circle with your method right after. MUCH THANKS SERIOUSLY
I've watched this every morning before my tests. This has been super helpful for me, thank you! This definitely has made all the difference on my performance
Drew out the whole thing from memory after watching this video, amazing! Really goes to show that behind every good student is an excellent teacher.
I was struggling with remembering this but you made me memorize it in 12 minutes! God bless you honestly, thank you so much.
I remember watching this video during my sophomore year of high school and now Im in my freshman year of college and I'm back to watching this vid
YOU'VE SAVED MY GRADE GOD BLESS U
10 years later and this video is still helping students. thank you!!!!!
I was searching for exactly this, and I'm so glad I found your video. I might actually pass my exam thanks to you. It really did take 5 mins!
For the forth quadrant just multiply 2 and subtract 1 i thought that's what you were gonna say when i thought about it and Thank you so much im in college and you may have just help me pass my final
Yeah, same here. I memorize the quadrants as Q1= 1, Q2= 1 under, Q3= 1 over, and Q4= 1 under half.
OMG THANK YOU THIS HELPED ME OUT SO MUCH FOR PRE CALC!! My teacher wants us to memorize this and know it so well so I needed this so bad lol. Thank youu
Coordinates - 1:22
Radians - 6:16
Degrees - 8:31
this video literallt saved my life!!! thank you so much, I didn't understand the unit circle at all and was freaking out over a test I have tomorrow, and now I completely understand! You're a lifesaver!!
i remember using this back in 10th grade
yessir
dude I am ur big fan!!!! underrated comment
No name?
woah, didn't expect to see you here
Probably ur least liked comment. Didn’t expect to see you here.
THIS IS LITERALLY THE MOST HELPFUL VIDEO EVER!
Thanks. I went through so many videos and none really made it easy to memorize and were all over the place, this is by far the BEST one, you make so much sense and make it so easy to memoize.
6 years later and you’re still helping people from this thank you!
my test is tomorrow, and I could tell u that I finally learned the unit circle, thanks
I usually don't like commenting on youtube vids, but I just had to say you are a rock star!! So helpful and easy. Wish me luck on my first Calculus exam tomorrow!! Thanks!! (:
How's the results will be come
I LOVE YOU. MY TEACHER NEVER EXPLAINED IT THIS WAY AND I NEED TO KNOW THIS TO PASS MATH CLASS AKA GRADUATE AT THIS POINT. I JUST LOVE YOU MAN
here literally 10 years later and you're still helping out. ty
this is by far the best way to remember it. thank you
hi
This is amazing- ITS SO SIMPLE!!! Thank you, wonderful job!
This is such gold unintentional ASMR!! Her voice is so soothing.
It is! I was getting tingles on the top of my head, not right away, but once she moved her cup (or whatever it was) over, and after that point, her voice would tingle me. Also in some unrelated lecture videos when the teachers write on the whiteboard, that triggers me.
You are the most amazing person. I'm taking my final for CALC 2 today and I was never able to memorize unit circle until I've found your video!
Thank you so much for this. I got covid and missed the first two weeks of the second semester and I had to learn everything on my own (including DE trig). This has helped immensely
yo i know how it feels. i recently just transferred back to in-person school and not having the ease of the unit circle in front of me while working was terrible.
Published 4 years ago and still helpful.....спасибо
The fuck did you think was gonna change about it, shits been around for 400 years...
+Garrett Green Boy chill. You know what he meant.

THANK YOU SO MUCH!! This 12 minute video helped me way more than a 1 hour lecture from my professor
this woman deserves a reward, thank you so much!
Best video on youtube for memorizing the Unit Circle quick :)
Thank you so much for this AWESOME VIDEO. Finally I understand the unit circle. You just saved me on this chapter. Bless you.
bless you for saving my grade rn this is the quickest i’ve understood a math lesson in my entire life omg
you are amazing :D still helping people out over 12 years later! thank you so much :P my teacher sucks at explaining the unit circle haha
the equation to use for the q4 radian measures is 2 times the denominator minus 1 to get the numerator
For the 5-7-11 in the radians, you can use 1 less than twice the denominator.
Most helpful video I’ve ever watched, 2022 and your still helping people out
eyyy 2024, and this video literally saved my life. thank you so much for this! 11 years ago and still useful up to this day. amazing!!!
Out of all the videos I've watched this was the most helpful. BIG THANK YOU

Thank you for blessing me with this
This is a awesome video. I know its old but this has legit helped me more then my teacher who has a masters in mathematics. you are a gem and should be proud of who you are.
I know this was posted a long time ago, but......OMG...THIS IS THE BEST EXPLANATION EVER. For so long i've had some trouble finding the right pattern and memorizing...literally after watching this video I drew the entire unit circle without looking at my notes!!!!!!!!!!
Super good video! My math teacher honestly has a hard time teaching so this really helped!
A lot of teachers suck
Jose Hernandez Preach! Amen!
found this very helpful. thanks a lot, you have saved me grades.
this is literally the best thing in the world. GOD BLESS YOUUU
oh my god , bless your soul i literally couldn't memorise it for the life of me before i watched this 🙏
Thank you! You helped me get an A in my Calculus class!
Thank you for making this information available to us students!
this is gold, pure gold. My exam is on friday, and I feel so much more confident. Please make more videos on math material, you are god sent
NEVER IN MY LIFE HAVE I COMMENTED IN A CZcams VIDEO, BRO I LOVE YOU, W MANS.
Great job, pattern recognition is everything in math.
Couple this technique with the "Left Hand Trick" and students should never get a problem wrong.
The mnemonic for the 4th quadrant radians is a good one; 5 days during the week I go to 7 - 11.
I will never forget this. The only thing I would have added is that the
X -Y is also the Cosine, and Sine. 😆
hi
A very helpful method for getting these down quick. An easy way to remember the radians in Quadrant IV is 2x-1.
hi
genious you saved my life!!!! failed my class once before because when I reached the unit circle I couldn’t do it anymore. second time around this is a life saver!
You are a life saver! I was sitting in my trig class thinking...how the hell am I going to remember this? You have been so helpful, because of you I remember the unit circle!!!!
This has totally saved me. Thank you so much!
hi
also me
FU**ING GENIUS SOMEBODY GIVE HER A EMMY!!!
an emmy? Lulz....
Best memorisation video seen by me on the unit circle so far.
It rocks, thanks for sharing!
honestly you're a legend, ive been up for 5 hours trying to figure this out until i crossed this video. this technique still works even after 8 years of the video being posted.
this helped. a lot. -_- thank you!
This is an old comment but omg hello!!!!!
what the hell are you doing here
This was really awesome. Thanks. But u didnt mention the ordered pair for 0, 90, 180 etc. Or the radians for that. But this really helps by seeing patterns and stuff. Btw, after you have radians in terms of pi, I think it's easier to convert them to degrees instead of memorizing the +30 or +15 stuff. Just cus pi=180 so plug in 180 for pi. 3pi/4 can be 3*180 then divide by 4 and u get 135. Also for 90 its pi/2 cus 180/2 is 90. At least thats how i see it. But then u just have to remember (1,0) for 0 and (0,1) for 90 and so on but it isnt that bad. Its amazing how much easier stuff is when u can make connections and see patterns. So thanks again for this awesome vid.
FIRST VID A BANGER GIRL THANK YOUU
You explained it a thousand times better than my teacher, which is ironic cuz they are paid to help us remember this kinda stuff, but instead, I was able to easily memorize it here, and for FREE.
"You'll be kosherrrrr ... " lmao
For Quadrant 4 you can just add the bottom with the top number in Quadrant 2. For 300 degrees it is 3 +( 2╥ ) from 120 degrees. For 315 it is 4+(3╥) from 135 degrees. For 330 degrees it is 6+(5╥) from 150 degrees.
This helped me remember the whole unit circle in 2(12.46) Minutes. Am sharing this video to my whole class. Appreciate you👏
For radians... in the last quadrant... Just as you subtracted 1 from the denominator and multiplied it by pi in the second quadrant, and added 1 to the denominator and multiplied it by pi in the third quadrant, in the final quadrant, you take the denominator x 2 - 1. Multiply by 2 and subtract by 1. 3 x 2 = 6 - 1 = 5 x pi = 5pi.
That helps a lot. Thanks
ifabodymeetabody Haha I also saw that directly :)
ifabodymeetabody your both killing it!
