Yo mr tutor, thoughts on the new mario movie?
You taught me in 12 minutes what my teacher couldn't in 6 weeks... from all the people learning this the night before a test, thank you!

Nah, this taught me what my teacher never taught me which I need to know
Honestly. Been searching TH-cam for hours for examples like these. Thank God!
why do i feel exposed by sympathetic
OMG WHY THE HECK DO TEACHERS OVER COMPLICATE THINGS WHEN THIS MAN LITERALLY EXPLAINED IT IN 2 MINS!??? THANK YOU FOR SAVING MY FREAKING LIFE!!!!!!!!!!!!
True!
12 min video btw
THATS WHAT IM SAYING DMSKKSKSKA
U r studying hard ik u want to go to Korea 🤪💜
It's simple.
The more they complicate things, the harder classes are. The harder classes are, more students fail. More students fail, more students retake classes.
Students retake classes = money.
or
Some professors with egos think
Harder classes = bigger penis
his monotone ‘why does this keep happening’ killed me lmaoo
This is the absolute best explanation of the basics of trig for people who have a visually-oriented learning style. Thank you so much.
Yeah I don’t understand very much taught in school so I have to look at videos on TH-cam because they explain and provide examples so well I am able to understand
This is the most helpful video on trig I’ve seen. I’m a sophomore in college taking calculus and still didn’t know how to do trig until this video.
"This computer has issues" quote from the organic chemistry teacher. 6:16 to 6:28 is my faviorte part of this video lol. Good job at explaining this concept. Most teachers make these kind of things so difficult to understand.
I chuckle a little in those time stamp tbh😆😆
When I heard that I instantly knew I've watched this video before. Its so rememberal.
Good job man! Trig is interesting yet many studens are struggling with the most! Good explanation
I had a hard time understanding trig and still do and came to the conclusion that it would have been easier to understand if my professor had explained this to me on day one.
Best Math tutor ever with a cool and calm voice 🙌🙌
You're my inspiration 😇💪
For the co-terminal angles...
The multiple of 360 closest to the number in question could be used to get the co-terminal angle a bit faster.
Who agrees with me??
Why don't they teach us that way at school??? Cuz it's sooo easy and understandable now! Thank you
I agree to you 🙃
How do you think they make money?
@@NganTran-se2ip taxes. they can still teach us an easy way and fill in with other math in the curriculum
1000% agree
My teacher was making us use a circle instead and memorize where everything went, this makes it a lot easier
Crazy how i am learning trigonometry in less than 15 minutes when my teacher spent a week teaching us and still didn’t make it easy to understand. This man is a legend. 🙏🏼
This Channel literally walked me through my entire academic path.
You have single-handedly cleared all my doubts, and for that I am thankful.
If you find science boring you, means you're learning from the wrong teacher, sir you're the best cause you make science super interesting, thanks very much.
I could not figure this out for the life of me, and then I found this video and got it instantly! My teacher couldn't get through to me on this! Thank you so much! This is a life saver!
My Trig final is tomorrow and this is the one thing I had left to go over, so glad I could find this. No clue why I was never able to understand this, it's so simple seeing it this way lmao
I studied electronics engineering and worked several years in my field, but finally decided to teach math and physics in school about 17 years ago. When started, I used this type of explanations (excepting SOHCAHTOA). Of course, they were straightforward and effective, but I was instructed by my coordinator not to do it that way because the aim is to teach math reasoning, not memorization (and SOHCAHTOA is mnemotechnic). Ever since I have been struggling with math-hater students who kind of demand the easy way of learning. Well, after explaining the math concepts and principles behind, I use this method in remedial sessions. Of course, students get it right away. Alumni who shared their experiences at university refer that what seemed to be a disadvantage at the beginning turned into an advantage because they could understand better what was going on. Don't get me wrong: the explanation is great and I found a couple of tips for my classes.
omg dude you are a lifesaver man. I have not done trig in like 4 years man, I took Precalc when I was a Junior in Highschool. Really needed that refresher, thank you ever so much man
Did you get the degree?? wishing you the best!
the only way to help this guy back is to watch the ads that popping out on his video and I'm going to write this comment to all of his video for you to know you can help him back by just watching his ads
4 minutes in, it just solved me 2 test problems.... thank you my good friend!!!
MR. Organic Chemistry Tutor, once again this is another solid video on finding The Exact Values of Trig Functions.
I coincidentally have an exam about this topic today. Thank you for doing this video man.
This was great. I'm used to seeing triangles on the unit circle an hypotenuses of length 1. I got very confused when I saw a triangle with a hypotenuse of 2. Then I realized you just stretched everything to a factor of 2 which made me think more about it. It was great.
We, students, have been blessed by the gods because of your presence
My teacher is good and All, but there are something's that teachers cant explain to students but only ULTRA LEGENDS can
I was looking at stocks for 4 minutes instead of my teacher doing this, thanks so much for the help.
Honors pre calc here we went over this in like less than a week and thanks a lot for saving me for this upcoming quiz.
Listen man. I've got a test tomorrow, and you, you absolute fucking legend you, just saved that grade. Not only so I no longer have to memorize where radians are on the unit circle, but I can convert to degrees so much quicker. My teacher failed to connect the relevance of those two triangles to the problem. Thanks homie.
I know that this video is older and everyone else has said this, but wow. You really are insane at teaching stuff
I found a lot of videos honestly from yt but this is the most clear. Thank u!
Mate your a life saver currently diong civil engineering and mate you help me alot.
I was so confused by my teacher. You explain it so clearly. Thanks
i just wasted one hours of my instructor explain this crap from the moon and back i can't understand it. after 15min of your videos it make so much sense.
ur better than all my math teachers combined
I hope jg likes my comment and how does he know this stuff and I mean all of this stuff but again we need people like him. I watch all of your videos, again I hope he sees this comment and likes it
That was so simple and easy to understand omg. I swear it was never like that when my teachers explained it-
Him.."Why does that keep happening? This computer has issues" Me...🙃😊you talking to me 🙏🌞
you're literally saving my life. thank you so much.
Great video. And I'm not even done watching it yet.
Yeah right me too
I am generally terrible at math and learned more from this than my teacher in almost a full week. THANK YOU LMFAO
I re-watched my teacher’s video multiple times but still didn’t understand until I watched this video once and I could do my homework 🤭
This is so goood. The man understands it and make it so simple to understand trig
Best ever man i saw teaching❤🙏❤
I wish my teacher would let me use TH-cam tutorial trig equations. They wants us to use their own trig methods and it’s annoying. I wish I can use this method. They talk too fast and I barley understand them.😐 Anyways, thank you for putting this out, It means a lot.
This literally negates the need for remembering the ASTC rule and doing calculations. Thankyou :)
bro you help me a lot. I am watching it 16hr before the exam
thank you so much for this vid!! i was so lost before but now I have an actual understanding of how to do this
Not the hero we deserved, but the hero we needed
Damn you’re pumping out the vids!
I’ll check them out if I ever need help
You are a hero. Have an amazing day
Thank you I have to learn Trig over summer for calculus :)
Wouldn’t it be easier to know calculus before trig
@@vincebutolder9921 no
Bro just casually saved my semester grade.
You r absolutely amazing
I struggled prior to this in trigo
same
In India, our teacher taught us trigonometry functions as -" Pandit Badri Prasad, Hare Hare Bole"
as - P | B | P
-------------
H | H | B
Sin= P/H ,
Cos= B/H
Tan= P/B
Hope it helps!!
you're the greatest to ever do it thank you so much
THIS VIDEO REALLY HELPED THANK YOU SO MUCH 🤗💖👑
6:17 computer has some beef with this guy...
Thank you so much. I was real pressed abt this topic the day after we learned it and you helped a lot!
Thank you man for saving us 😍❤️❤️❤️♥️♥️♥️❤️❤️❤️
Thank you! I really can't express how helpful you are!
Wow so helpful I finally understand!
Need more info for electrical engineering calculations, power factor of 3 phase systems for example, thanks for all your videos
Thank you,teacher
You have 1,77 millions student
You are a angel man, Thank you.
Make it so simple to grasp...
Thanks...
you saved a soul thank you🙂❤
Thank you. This helped SO MUCH
oh my god. you're the saviour
was stuck on a question similar to these and I fully understood it after watching. Thank you so much
YOU’RE A LIFESAVERRR
You are so helpful, Thank You.
you absolute unit bruhv !!! subscribed and liked
Thanks for the lesson
Bro taught me everything my teacher spent 3 weeks trying to in no sh*t- first 4 minutes of the video ☠️
1:54 when we write cos(5pi/6) does than mean the value 5pi/6 is radian then, why dont we write 5pi/6 rad , like we write 30degrees ? Idk if i sound stupid but…….
I'm pretty sure if it has "Pi" in it at all then it is understood that it's in radians, so you wouldn't have to put rad after.
Trying to figure this out before my exam tomorrow
Omg u just saved my life
THANK YOU i understand now🍀
literally saving my math grade rn
My best tutor
By watching the thumbnail at first , I did :-
Radian to degree conversion by multiplying the given value by 180/π
10π/3 x 180/π = 600°
Sin 600°
Sin ( 630° - 30° )
Since 630° lies on Y-axis on trigonometric functions graph , sin will get converted into cos . Given angle(600°) will be in 3rd quadrant , so cos will be -ve . Hence final value will be:. -COS 30° = -(√3/2)
But your method is easier ...
I cannot thank you enough…. This seemed impossible to learn from my teacher
If only my teacher taught this to us. But we are literally graphing cos, sin and tan graphs
Thank you so much man this is much appreciated
Well Done Lad.
This video is excellent. Thank you for the help!
Oh my god my dumbass teacher could've just played this video instead of wasting my time explaining for 2 hours. Thank you.
This makes so much sense.
This man is amazing !
Thank you so much this really helped
Thank you, thank you, thank you!!!!!
Yo i love this man- if u can teach a dunce like me im saved
When you watch this kind of video, with this kind of explanation, and you compare it to what 99.9% of all people are subjected to in school, you quickly realize why math and science are the most traumatizing subjects for people to get exposed to.
This is some powerful stuff.
Thank you so much! This is very helpful.
Your the G.O.A.T🔥
Actual life saver
Dude you're awesome
Thankyou very much my guy! You helped a lot :-)
Thank u so much man👏🏾
