Maths Tutorial: Trigonometry SOH CAH TOA (trigonometric ratios)
Вставка
- Опубліковано 15 чер 2011
- SOH CAH TOA is used to remember the trigonometry ratios; sine = opposite over hypotenuse, cosine = adjacent over hypotenuse, tangent = opposite over adjacent. This helps you work out unknown side lengths or unknown angles in a right-angled triangle.
This video is a tutorial on how to apply this rule.

is anyone watching this the night before a test
meeeeeeeeee
me but I forgot everything as soon as the teacher said "begin"
yea
BAZZA yep
the morning before*
Here I am trying to teach myself how to do the homework they assigned me with no understanding of anything during quarantine :,))
jz posted video on how to calculate trigo without calculator......i hope its helpfull.....and more videos coming soon
lol same, have no idea how 2 do the hw
@@ishamathstea9019 I asked that question to my teacher, what if one doesn't have a calculator, he kicked me out hahahhaah that I just wanna challenge him.
@@johnx8125 Wow 💙💙💙
SAME lmao
Took me 17 minutes to fully understand what my teacher taught for 1 hour that i didnt even understand. Nice. Thanks!

Try 4 years ...
One month of constant lessons, study guides, and homework by a teacher who's been in collage for 4+ years
Or a 16 minute boi
FBI open up
Well it rounds to 17 minutes 😉
17 Minute Boi wins
As a 6th grader, I understand this really well
taught me more in less than 20 mins than the 2 weeks in class.

We expect to get spoon fed by our teacher but they don't teach us everything. It's our responsibility to ensure we put the time and effort at home.
Mythical Studio Not really
Every year, we spend 180 days, 5 days a week, 6-8 hours a day (depending on the school you go to), in chairs, supposedly being educated. Many of our tax dollars (though perhaps not enough when you look at the wages of teachers) go into this supposed education system. If teachers insist on teaching things like algebra and trigonometry, while also insisting that we will use these "skills" after we finish school, then they *should* teach us everything, whether useful or not. 6300 hours of school per year should obviously be enough to learn everything.
*Continued rant:* Teachers also insist we practice these "application" problems where we would use these formulas in a supposed real life scenario. These include figuring out how much time it would take for a ball with a given mass to reach the ground after being thrown at a certain height with a certain amount of force at a certain angle, or perhaps finding the length of a drop based upon how long an object spends in the air. In real life, guess what? Not only do we not care, we are not going to accurately measure things like the amount of force given to an object or the amount of time it spends in the air. So we spend weeks and months learning about useless formulas that random Greek mathematicians invented for whatever reason. My point is, it's all useless. We don't care, we don't use it, and I'll stand with this view point until someone proves to me that we won't have Google forever.
Don't even get me started on history. Not only do we spend years learning about the history of America or the failure that Christopher Columbus was, there aren't even supposed "application" problems where ANY of what we learn in history class is is applicable to real life situations. We are always given the mindset that it doesn't matter what happened in the past, only what we create in the present and future, right? Well, then, what's the point of 180 hours of History lessons a year? Sorry, but History Class makes NO sense to me at all.
Sorry for the rant, I just have the need to express my thoughts on the supposed education system.
No hate, I just needed to vent some feelings I've been going through.
PS My school bought 60 touchscreen monitors and new computers for the school library, but somehow they can't afford edible school lunches.
Lupe743 I partially agree with you I agree with you on the first part but not the part about history I could be biased because I personally enjoy history, the syllabus in oir countrt for history had to be revised be u stil enjoy, you might not realise this but things are repeating the point on.history is to look on the past, study it and try and improve on that so in the future these mistakes won't be repeated, sadly these mistakes are still repeated this because imo many people, like you don't give history enough importance, I get your pont but I personally dont agree with it.
Math makes me depressed
Same😢
Ngl so true
Nah math makes me feel so smart 😭
Holy God. Please replace my math teacher. I actually understand for once.

But, I understand some things. When I ask for her to help me on something, she doesn't explain it comprehensively.

My math teacher literally doodles on the board... I’m in an advanced math class and our last test average was 57.

You just saved my ass on my exam. My math teacher can't even teach for SHIT!!!!!!!!
THANK YOU BTW
or maybe you jus dumb
@@16piecemcnuggetmeal18 if he is then why is this so much easier to understand with just a single 16 minute video?
For those who may be confused how she got 8.18 for Sine, she used her calculator * twice. * First she entered the measure of the theta angle (43) and hit the SIN button, yielding 0.069. Then she multiplied that by 12, which in turn yields 8.183.
Wow, thank you so much for this!!!
Thanks
Thanks, the info helped
❤Thanks for the information
how did she calculate the (43) and the SIN?

Am I the only one who's watching this because the maths teacher seems to be speaking a different language on online classes ?
You’ve basically explained to me what I was supposed to learn over and entire in 16 mins. Hands down, the best teacher ever. Please teach me.
10x better than my maths teacher
no way you were here once in your life haha
@@Finninin4915 lol
The reason why im here because i don't listen to my math teacher because he's talking fast
Bro ur here-👁👄👁--👄--👁👄👁
Btw same😭
Least you didn't get that one teacher who got fired for teaching it in a racist way lol
you know why people mostly always say that they study better from the internet , its probably because your teacher has more than one student to teach(and even worse if the class is a naughty one) while youtubers have all the time and can repeat until they get it right also it feels like they talk to you.
just a thought : )
You are so right.
My class has 14 pupils and we are all disciplined but the teacher just doesn't care
@@Sallyskin now thats just annoying
I swear this sounds like some kinda spell straight out of Harry Potter
OMG thank you so much you have no idea how much this helped me!! I've been failing in math for some time now and i really needed to bring my grade up but with this video, i finally aced my test!! You have no idea how thankful i am! My teacher even talked to me after class about my grade and i showed her this video! sure its long but it helps so much!! you are great at explaining things and i loveeeeeeee the examples you provide!! You have made our lives so much easier and you dont even know how thankful i am!! Thanks again (for like the 500th time lol)
+Neena Parikh Wow, this comment made my day :) You're welcome! Congrats on acing your test!
shut the f*** up
Sami Marouf Fuck off dude
ill hack ur utube then...
samip science they’ve clearly tried to, the teachers methods probably didn’t work for them and the explanation within this video did, no need to be rude about it
learning this for the past two weeks, GOT THE WHOLE TOPIC IN LESS THAN 20 MIN! THANKKKKKUUUUU
I'm not even going to lie here, this was better explained on this video than it was in class and it's really complex to understand but it was 1) peaceful, no shouting classes or disruptions which was good. 2) Gave me a boost to my GCSE's that are 6 weeks away and this helped so much. Thanks (I'm also failing at English so sorry if this was difficult to understand)
School failed. This video is much better because 1) peaceful, no shouting, no bullies bullying people while the teacher ignores it -- it's what they do most of the time, and people saying otherwise are the bullies trying to keep things under wraps 2) no suspensions for using self-defense after being attacked by a bully, which schools are famous for -- there are no excuses for that kind of behavior, even by pro-prison/school people 3) no school shooting after the bully plays the victim on social media, no victim blaming, no harrassments and see-through backpacks, and then more bullies come back with daddy's pistol to shoot the classmates because they "saw it in a videogame," _cough_ knew they would get away with it if they blamed videogames, because senators really are that senile and stupid, and would rather suspend our happiness and games, than deal with domestic terrorism or inequalities in the Weat _cough_ Roe V. Wade being appealed, racist/sexist anti-mask, anti-abortion, anti-immigrant teachers who are too stupid to teach anything but bigotry 3) videos on UA-cam teaches us more in 8 minutes than 24 tyrranical, liberal authoritorian-traumatic years would teach us in schools.
There are no excuses for the lack of effectiveness of the global school school in the West. The teachers say that girls get to have phones on (the boy's phones get locked up in a box) and get treated better in class, because life isn't fair, and I should just suck it up. My teachers also say that men are inferior to women, and that all immigrants and those with middle-eastern pedigree are terrorists. There is no excuse for the horrors you get in schools, for the PTSD/war shell-shock that you would expect to see from a Vietnam survivor, the kind of abuse your superiors dish out, far worse than any war -- in war, 100% of all soldiers aren't children being pushed and commanded by adults (regarding the idea that everyone is just a foot soldier in the plans of the tacticians and commanders, applied to School), and the rest of the adults simply being incompotent fools who can't lead a division. And yet, in schools, that's how it goes: if this is how much I can learn in 8 minutes, and looking at the part where I have always been studious and faster than my brain-dead peers -- through all 12 years of school, all of what you cover, if you remove the repititions and mindless scribbling that is 99% of school, it would be compressed to one year, or maybe a month, based on how little you do there.

@@bedriamuhsin7481 did you pass
@@noonbahar6916 no 🤗😏🤔😁
@that dude It's because you have the brackets in the wrong place. You are asking your calculator to work out the sine of (43x12), as in the sine of 516. Instead, it should be the sine of 43, multiplied by 12. So you are typing sin(43x12). Which is like asking sin(516). Which will give an incorrect answer of 0.40 The correct way to enter it into your calc is sin(43) x 12 which will give you 8.18. Don't worry, this is a really common error. I should definitely have explained that better in the video! Hope that helps :-)
thank you u just saved my life thank youuuuuuuuuuuuuuuuu :) :)
Piper Roser you know the one with no angle how do you do that i always come up with 65 not 66
Oh my god thank you so much
Thank you
vcefurthermaths WOOOOOOOOOOOOOW ...I just did the same thing as in your top comment...and smashed my new computer against the wall and killed things -after 2 hours down drain wow
This is honestly a life saver. With an exam tomorrow for math, this video helped me so much. Thanks!
my teacher is really stupid and you just saved me.
If your teacher was stupid they would not be a teacher.
depends, he can be stupid with the students and not with the director and other teachers.

I love you! Your saved me. I forgot what my teachers taught me in the past school years, and now these trigonometry questions came back. I'm having a hard time answering my modules even though I already learned it before. Now, I'm struggling where to start. You saved me. Having a teacher really is better that self-studying. #facetofaceclasses

Oh my gosh. I just finished having a mental breakdown because I didn't understand anything and we were just introduced to trig yesterday, but we're expected to complete an assignment by tomorrow. And to top it all off, since schools are closed I had to teach myself, and how do you teach yourself when you know nothing and the teachers aren't helping?

BEST VIDEO IVE EVER WATCHED AND ACTUALLY LEARNED FROM LOL
for 16:40 you can just do 9x9 and 8x8. 81 plus 64 = 145. then do the square root of 145 and that gives you 12. its easier in my opinion. the opposite and the adjacent will always equal the hypo in a right triangle.
It depends how well U are in Trigs. U know, Pythagoras is always longer that just using trigs ratios. U can use trig in all cases, even if U are not given an angle at all, but this would be complicated :) For example, when to use Pythagoras and when to use Trigonometry I explain here : ua-cam.com/video/WYRSEnNIDwY/v-deo.html
Thank you so very much for breaking the problems down for me. I had to do a project on this and I thought I'd never be able to do this thank you, miss.
You're honestly a superve teacher, i've struggled with this subject for 2 years and hours of work and you short lessons, condensded into 16 minutes have taught me more then the past 2 years. I speak on behalf of thousands of people who have watched this video to say, thank you :).
10 years 💀
Absolutely perfect. Explained clearly, steps were shown and easy-to-understand diagrams! Thank you very, very much :]
I thought I was going to fail my test tomorrow in class because I didn't take notes and I didn't pay attention but now I understand what to do and it makes way more sense now. I really appreciate this video and how helpful it was!!! Would recommend to anyone learning this subject.

*places protractor on board and measures angle using that device
I JUST BLEW YOUR MIND!!!!
excactly, this is what teachers don't understand
***** last time i checked i wasn't a ww2 pilot
Ziot what do you mean not to scale ... angles are angles no matter how long the line
Lord_Lammington they could show an angle that says 34° so you can do the excercise, but the angle may actually measure 31°. Its done like this so you can measure the things and so you have to use sohcahtoa
God damn you are stupid, not ever question you get is to scale. They teach you how to do this since you will not always get the chance to use a protractor.
Glad you liked it! Thanks for commenting :)
Thank you so much. I totally not understand of what my teacher is teaching. Luckily I saw this video ,thanks for sharing.

to change the mode (on a scientific calculator) you press shift and the mode/setup. I list will show up and in that list there will be deg and gra. Next to them there will be a number press the number next to deg. To check your calculator is on degree mode you have to look at the top of the screen and if the D is there then your in degree
Hey thanks! I'm glad you liked the explanation. There are a few different ways to explain it, but this way of thinking about it is what seems to make most sense to me. Thanks for commenting! :)
You taught me everything my teacher tried teaching us, in 16 minutes. I actually learned it this time!!!
i love you man thank you, teachers in mainstream schools make it more difficult then it actually is.
I'm in CCSS8, and I just found this on my recommendations page, I just got a notebook and wrote down the stuff you mentioned. Not 100% sure when this is used, but it was really fun actually!!!
Who is watching before a day from the exam😂😂
i did the last part of the last question on my calculator and kept getting a different answer. i put my calculator into the right mode and tried putting brackets and moving the times to before and after and still got a different result.

I already love this lady. Thank you u helped me more than my teacher.
Thank you! You explain at a perfect pace and pick up on every bit that anyone can get confused on like me!!

have an exam tomorrow, and trig is the thing I have struggled on for so long since leaving my last teacher, who practically taught me everything I know (and is the only reason why I passed). I have left it to last minute because of how much I dreaded it. Upon realising my teacher has all my books from the past two years I needed to revise from, I was left with no other choice but to use the website my school maths department recommend. The methods they used were completely different to what I used, and being the only class that used the method you displayed, no one else could help. I have picked this back up, and will have you to thank when I pass the trig side. Thank You!
I'm trying to get into a college math course from in 8th grade, and I really needed to know this. So thank you for helping me undertstand.
