When I acquire my 1st engineering job, a house and a relationship, I'm sure as hell donating an arm and a leg to you because you are the reason why I'm succeeding in my college career.

6:06 Special right angle triangles
17:10 Exact values
22:15 Exact values of angles greater than 90
32:40 Exact values of angles greater than 90 negative example

"hm, i almost lost my train of thought there"
A great reminder you're also human and not some super smart math android with a cool voice, haha. Thanks so much for taking the time to make these videos!

This helped so much. You're the reason why I'm actually getting As and loving physics even more. Thank you

My man's going to heaven, for real💯

I know I'm late, but you are my trig savior. Watching this playlist brought my grade up 2 letter grades, and I seriously can't thank you enough

I don't mind if you read this or not, I've been watching you for years. I have no words to explain how much of a help you have been to me; you are the major factor for the straight grades and best math student awards I received throughout my career. You are the GREATEST math tutor I've ever had, I respect you from the bottom of my heart thank you

MR. Organic Chemistry Tutor, thank you for a solid introduction to Trigonometry. This is a beautiful start to old fashion mathematics.

I wish you were a teacher for computer science . You explain EVERYTHING so well in all of your videos . It's remarkable. Thank you for these videos 🙏

Grade 9, my teacher didnt finish this trig because of pandemic.. now im in grade 12 and taking physics and I need to go back to this.... You helped me a lot my hero. One day when i have finished my study I will support this channel by being a youtube membership... but for now I'll be just an avid learner

This channel has helped me since 2011 when I was grade 8 thanks at all I am Ethiopian University student many Ethiopians are following you keep like this

Bro ,i love you,YOUR EXPLANATIONS ARE AMAZING.Just imagine to how many students did you help,you are doing crazy stuff man

It's gonna take some years for me to finish studying, but when it does finish I will definitely be back for you Organic chemistry Tutor. Thank you so much for making videos like these where a student like me who lacks guidance and who doesn't have a good foundation is Learning and building up his own foundation. You're amazing for making all these free resources for us. Thank you.

i am going to have test tomorrow with this chapters it help me a lot best math class i have ever had (You save my GRADE)

You are the true example of a true real teacher
Iam impressed ♥️💙💚❤😊thank you so much sir

I sat through the entire video on 1.5x and I have a good grasp on basic trig now... Thank you.

i jumped straight into calc in college without any prior knowledge to this stuff and was dying. im giving you $1M when i make it brother i swear

as a kid that is still in middle school I found this video very helpful and easy to understand and keep up the good work

I start my undergraduate as an engineering freshman in about a month and a half, this man is the reason I'm here at all. Big thanks to you, Organic Chemistry Tutor 🙏 When I graduate in 4-5ish years I'll definitely have to come back to this video to drop another big thank you for helping me through my college days lmao

Just randomly woke up to this and remember using this guys stuff years ago when I went back to school at 28. In my 30s now getting ready to do a crown prep exam in dental school.

I'm going to take BSCE as my course. and some video said i should master trigo. And there you are my savior. Thanks alot

I want to say thank you so much, I was scared for my trig course next year but now I feel better thanks to you

For the basic values of theta for sin cos tan (0,30,45,60,90) you can use the trig hand trick
Face your palm toward you and label your pinky (0°) and move up with the other basic values.
To find sin(30°) count the number of fingers below whatever finger is labelled for 30°(ring), so there is one finger below your ring finger(pinky)
For sin:
Sqroot of number of fingers below/2
For cos vice versa:
Sqroot of number of fingers above/2
For tan flip your hand over so your nails face you(your pinky is still 0 but it’s counting down now):
Sqroot of the number of fingers above/number of fingers below
👍

Thank you. these videos are very helpful to me because my math teacher doesn't actually teach anything, he just has us read how to do it online and watch videos that don't help

the only teacher u need is this man, and all of youtube

I salute you, Mr. Organic Chemistry Tutor.
You explained the unit circle like no one else before and you nailed it.

Just 9 yrs and this channel helps me learn

Here’s a formula for pythagorean triples. Given n>or=3, any odd length side n, which is the shortest side, take n^2/2, and +/- 0.5 to this number. And you have a pythagorean triple. For example, take the number 13. 13^2/2 = 84.5. The 2 other side lengths are 84.5 +/- 0.5, which is 84 and 85. And there you go. 13, 84 and 85 is a pythagorean triple. No need to memorize anything.

Not even in the grade which needs these math's, but still they're so entertaining to watch.

Best tutor, after following your tutorials I’m now confident

I seriously adore the guy of this channel, I could watch these videos for hours despite the fact I dislike math. Because he explains it so well. Does any1 know a similar channel for other subjects??

Notice how he almost never asks anyone to subscribe.....but we do cuz we need him

Your videos are helping me so much, got a rigging exam in a few weeks. And your explaining it so well, better than my teacher did many years ago. 👍🏼

Thank you so much for this video it really helps my high school, science students. You rock.

Your Video help me a lot in reviewing Algebra, Geometry, and Trigonometry I am sure I will succeed in entrance exam, because you're video give me ways to understand mathematics.

Sir you helped me pass organic chem, and Trig. I want you to know how much of a godsend you are as a teacher. As a person who despised science and math you have opened a new world of a clarity. For that I thank you.

I'm gonna take UPCAT(top university entrance exam here in Philippines) tomorrow, this vid really made me master Trigo in less than an hour😭
Ty so much!!!

Bruh please dont ever delete yo channel i might need this for future purposes, im about to get civil engineering in college, i got confused coz most engineering students complains about trigo its the hard one according to them so i immediately to go youtube and search it after a minute of watching i think i can solve it myself hahaah thanks

im only yr 8 and idk why im watching this BUT thank you for teaching me sir! very appreciated

I'm currently doing a year (junior hs year) abroad , taking classes in a language I don't understand. This is a life saver for me, thank you so much

you are best of the best teachers that i even sew. thx!

Without u mathematics could have been tough in my whole life. Thanks for transforming me.

you helped me went through everything in highschool and heplping me not losing my place is the honors. Now im in college because of you! thank you so muchhh

You are really a man ...
Each and every time you are proving that you are one of the best teachers ever🤗

Best math and physics tutor I've ever met

OMG, this is one of my favourite channel... OMG i love the way you teach. thank you so much. it meanns a lot to me. GOD BLESS YOU.😘

So helpful, Thanks for this Trigonometric Tutorial, You're the best teacher ever, my idol 💗

u r aweosome man rlly thank u i did watch most of ur videos and it helped me alot hope for me the best my exam is tomorrow

Just wanted to let you all know for the “all students that take calculus” to memorize the quadrants that each thing is positive. What helped me in high school was just memorizing CAST and starting in Q4, working your way around counter clockwise if you also wanted to try that quick phrase

You are really a genius
Thank you so much
Keep helping us by making these types videos

The way this video is holding together my trig grades and im really starting to love trig :) tysm

I learned SOH CAH TOA as
Two. Skipped carrying
Old Over. A
Angels Heaven Heart

You're a life saver bro. Keep doing God's work

i love how you take it slow it really helps other people

I WILL OVERCOME MY FEAR AND LAZINESS AND BINGE WATCH ALL YOUR VIDEOS SOMEDAY.

Sir can you please make a video on trigonometric ratios of standard, different, and compound angles
Because you teach very effectively and your other videos on trig ratios and matrix has helped me

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

you're a great tutor. i bow to you.

Im learning this as a Grade 7 student, overall Trigonometry is easy to comprehend or maybe it’s this guy who makes things easy to comprehend. Huge respect🥰🙏

im Turkish but i can easily understand this videos so tysm i loved it! life saver for real bshdhebfe

BRO ThERE MUST BE A WAY TO MEMORISE ALL ThESE FRICKIN FORMULAS

Ive been watching u since 2 years old now im 13 and i learned calculus by u. Keep up the good work

i like listening to educational videos while i fall asleep because maybe ill retain some info for when i eventually rewatch it

Wish I had you as professor, seriously I can’t thank you enough 🙏🏻

This guy is the rocket to my back thats gonna launch me to the top. Crushing it thanks to this dude

I use "Some People Have curly Brown Hair turn Permanently Black"..
Some (S)= sin
People (P)= opposite side
Have (H) = hypotenuse
Curly (C) = cos
Brown (B) = Base
Hair (H) = hypotenuse
Tan (T) = turn
Permanently (P)= opposite side
Black (B) = based..

This guy explains everything soooo good THANK YOU

thanks this is very helpful and complete as i prepare for my college entrance exam!

This guy is a beast when it comes to teaching

I don't need to go pay for Review classes anymore, this channel is lit and a lifesaver😍
I'm just 17 minutes in and already feel more confident in math, THANK YOU TEACH!

His voice😭❤️

found the maths lectures to learn finally. thank you

6:55 (pythagorean triples) 24:06 (exact values of a right triangle) 27:34 (how to get reference angles) 30:34 (which quadrant are the functions negative or positive; ASTC i wish i knew this during my junior year)

You thoroughly understand what you are teaching, that's why you are able to compress the material into totally understandable logical steps. Kudos!!!

All Students Take Calculus. I love it. So easy to remember thank you!

Hello, you did something wrong with the example of the sin of quadrant 2 because -root 21 time 21 is -21, not 21 only. I highlighted this only for people solving before the tutor explained. Also, I want to thank you very much for these videos; they are beneficial, and I have been a great supporter of your channel for a year or two. Keep up the great work!

Thanks for the video it help me a lot...and It help me to understand trigonometry without trying to memorize

20:37 we know that pi= 180 so we can directly subtitue it like 180/4 and get the aswer ,its a bit faster

I'm so freaking sad and I regret not finding this soon enough 😢 in my last year and I only got 2 month left for my final exams and I'm so bad at physics and math but thins guy is helping me sm now well let's hope I catch up with the lessons of the whole year in just 2 months

Praying I'll pass my engineering entrance exam on Saturday. Manifesting🍀🤞

Your voice is kinda like Ice Bear from "We Bare Bears"😊cute

THANK U FOR SHARING SUCH A ICONIC MATH THEME✌✌✌✌

We have to do trig in 10th grade now :( I thought it was for seniors and above

i like playing your vids and falling asleep to them

This is very very easy to understand, thanks!

I love your videos. You are GREAT at what you do. 😎

Best way to remember the SOH, CAH, TOA is to combine it into a word: SOHCAHTOA and pronounce it like, So-h-cah-toe-a

I love this lesson this is great

Waaaa your lessons are more enjoyable at last Ihave finally have felt the lo😍😍😍😍💕💕💓💖ve of maths

I’m 8th grade and I was curious about 10th grade math.Thanks for helping me understand

first time watching your videos and wow I really enjoyed it

I currently entering high school, not yet, but trigonometry is soooo confusing, but this 41 minute video is probably going to be better than my future teachers's one semester lesson.
When I start my high school business, I will be donating an arm and a leg because your the reason people who can't afford tutoring is getting education.

I thought It was hard.But after seeing this video It is very easy to do trignometry...🎉

in 15:22 there was a slight mistake he wrote 21 when it was supposed to be -21 by the way a great and helpful video

You're surely an A+ free provider🥺❤️

Since everyone is saying how this is a good resource along with practice lets pray that using this a study material will work. T_T

HI teacher, im 11 years old and my father said that i need practice of angles in billiard. I searched up in google and it said it needs to be good math (I guess not) like trigo. So i watched this. And sincerely. easy win for me ❤❤❤❤❤❤❤❤

I wish I found this guy in the beginning of high school I WOULD LITERALLY BEAT EVERYONE IN MY CLAS IN MATH AND PHYSICS I WOULD'VE BEEN UNSTOPPABLE SHIT MAN but I wasn't lucky enough to find it sooner

HE DESERVES MORE VIEWS AND SUBSCRIBERS.
