11 is opposite
x= is adjacent
?= is hypotenuse
Find x before solving for ?
@@RobertBryantDiloy-lg2lix could be any number, than to find hypotenuse you can use c = sqrt(11^2+x^2). i mean there a lot of solutions, pick whatever you want
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.
Did you get it
Please update us!
@@multi_editsj1851 I think he did'nt get it
@@gamerking-eq2xl he probably changed his mind that he doesn't wanna donate his arms and legs
@@gamerking-eq2xl rip
"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!
When he said that it makes him sound more like a robot
That sounded exactly like an android robot when he said that
Still a good video
My man's going to heaven, for real💯
fr he chose heaven 🥶🥶
Yesir
😂😂😂😭😭🤣🤣🤣 bruh 😅
@Anthony Leyte when did he say that💀
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
This helped so much. You're the reason why I'm actually getting As and loving physics even more. Thank you
You're very welcome.
@@TheOrganicChemistryTutor hello
27:57 how do u know length of the sides like 1, √3 ? I didn't understand that :')
@@irodaikromxonova9556 That is one of the basic Pythagorean triplets we use for trigonometry
@@avocadomusician2912 aha, you mean standard table?)
@@irodaikromxonova9556 Yes but for basic understanding: Use the smallest natural numbers 1 and 2 as perpendicular and base and using Pythagoras theorem you get base as √3
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 🙏
Yo im in highclass next year imma take cs, is everything going well for u?
@@s4j6e well, I'm taking four classes and my physics and calculus classes are accelerated so it's a bit of a struggle
BroCode is the goat of computer science he is like the organic chem tutor
@@EliasHaile-hi7ex no way?? Thanks for the info! 🙏🏼🙏🏼
MR. Organic Chemistry Tutor, thank you for a solid introduction to Trigonometry. This is a beautiful start to old fashion mathematics.
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
Bro ,i love you,YOUR EXPLANATIONS ARE AMAZING.Just imagine to how many students did you help,you are doing crazy stuff man
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
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
👍
This is actually very helpful. thank you.
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
Thank you so much for this video it really helps my high school, science students. You rock.
I salute you, Mr. Organic Chemistry Tutor.
You explained the unit circle like no one else before and you nailed it.
I don’t understand
I sat through the entire video on 1.5x and I have a good grasp on basic trig now... Thank you.
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
drop a fat dono
Hows the first weeks going man
@@user-hw5en6is2o its brutal out here, but i actually really like university. i feel like im thriving in chemistry and math but not so much in my actual engineering classes lmfao
@@warrenpostsstuff4364 How is the first year going man.
@SidemenLOLMomments First year went amazing, thanks for checking in! I made the Dean's list with straight As at the end of it, and I'm transferring into the premedical version of my engineering major this winter. It'll be brutal out here doing premed engineering 💀 but it'll be worth it.
And as always OChem Tutor out here still helping me through 🙏
Your voice is kinda like Ice Bear from "We Bare Bears"😊cute
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
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.
Best tutor, after following your tutorials I’m now confident
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
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
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
Just 9 yrs and this channel helps me learn
Don't care
Ya you have a grammer like a 9 yr old kid.
@@360bot7he didn't ask and if you don't care then why you comment
why does a 9 year old have to learn this
@@arina4030 mby just because they want to
So helpful, Thanks for this Trigonometric Tutorial, You're the best teacher ever, my idol 💗
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
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.😘
the only teacher u need is this man, and all of youtube
We have to do trig in 10th grade now :( I thought it was for seniors and above
This is very very easy to understand, thanks!
you are best of the best teachers that i even sew. thx!
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. 👍🏼
The way this video is holding together my trig grades and im really starting to love trig :) tysm
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.
cool
thank you for this omg
Bruuh i thought that everyone knows this formula
doesnt work with 8
@@beyourowncatalyst There’s another formula for that. Divide by 2 to get 4, square it to get 16, and +/- 1 to get 15 and 17. 8-15-17 is one of them.
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.

This guy is the rocket to my back thats gonna launch me to the top. Crushing it thanks to this dude
You are really a man ...
Each and every time you are proving that you are one of the best teachers ever🤗
You are really a genius
Thank you so much
Keep helping us by making these types videos
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
Are our brains connected 😮😁
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
I hope you did well :p
@@guardianangel1468 well I have passed with a B+ .. :p good luck with your study 💜
Thanks for the video it help me a lot...and It help me to understand trigonometry without trying to memorize
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!!!
thanks this is very helpful and complete as i prepare for my college entrance exam!
sir your work is amazing. thank you so much
Wow this helped me a lot thank you sir 🙂
BRO ThERE MUST BE A WAY TO MEMORISE ALL ThESE FRICKIN FORMULAS
They are really much😢😢😢😢😢
All Students Take Calculus. I love it. So easy to remember thank you!
you're a great tutor. i bow to you.
Love you ❤️😍💜 you helped me a lott
Thank you sir🙏🏾
U are indeed a life saver 👍🏾🤗
Waaaa your lessons are more enjoyable at last Ihave finally have felt the lo😍😍😍😍💕💕💓💖ve of maths
You're a life saver bro. Keep doing God's work
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
Such a good teacher!
im Turkish but i can easily understand this videos so tysm i loved it! life saver for real bshdhebfe

thanks bro. teach all igcse topics. u explain why we use some signs and stuff. really helps.
I love this lesson this is great
found the maths lectures to learn finally. thank you
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
what do you do in life now?
Wish I had you as professor, seriously I can’t thank you enough 🙏🏻
first time watching your videos and wow I really enjoyed it
JG keep making good maths tutorial and chemistry videos.
Sir,you're incredibles...🙏
All right!!i cant thank you enough for this!!❤❤😭✋
Thank you so much.......thank you sir May God bless you with health happiness and prosperity 💚🙌...i am indebted to you forever
THANK U FOR SHARING SUCH A ICONIC MATH THEME✌✌✌✌
Love this channel
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
Good video bro I really learnt
Thank you, You are a lifesaver
You have to keep doing this your so good at it you made me smart
You thoroughly understand what you are teaching, that's why you are able to compress the material into totally understandable logical steps. Kudos!!!
Thanks a lot, I really appreciate ❤
Just watching this 2024, I love this class
You really help us.GOD bless you 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
bro uyour'e on of the reasons im able understand these subjects!
Noted with thanks 🙏🙏💫
U are great teacher
we'll learn this in basic calculus tomorrow! gotta learn in advance haha
i like playing your vids and falling asleep to them
i love how you take it slow it really helps other people
You're surely an A+ free provider🥺❤️
You're an absolute amazing teacher! Now I'm gonna bash yr 9 trigonometry. I'm also wondering if you can teach us about/did 3d trigonometry?
i like listening to educational videos while i fall asleep because maybe ill retain some info for when i eventually rewatch it
Notice how he almost never asks anyone to subscribe.....but we do cuz we need him
Valuable channel
20:37 we know that pi= 180 so we can directly subtitue it like 180/4 and get the aswer ,its a bit faster
Thanx for the simplicity
The video was very helpful
My potato brain still can't get this
I’m 8th grade and I was curious about 10th grade math.Thanks for helping me understand
thanks a lot! 💛
Tysm, I'm now ahead of my class!
This is helpful thanks so much
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!
