- In this video I go through a brief introduction to trig identities. I look at well known identities such as sin^x + cos^x = 1, then go through some example problems. Part 2: • Secant, Cosecant and C...

Who else is here bc their maths teacher can't teach
Not me
My teacher is eddie woo hehe
Online classes are basically impossible to understand...
@@Frosty_V0 thats gotta be painful, can't you reach out to a tutor?
I can relate
I know this is a few years later, but thank you so much for making this. I was lagging behind my class, and I didn't know what the hell was going on. This really helped me out :)
Apologies for the sound quality in this video! I am clearly not an expert when it comes to microphones 😬
Maths Explained
Yeah you should be sorry 😐
It’s all good 😅
blessed favoured
It's not ok😡😡
Theres nothing wrong with the audio
Ok good to know thanks :) I thought it was a bit distorted but I am glad it's ok
Me studying in class:understand 10%
Online:90%

The truth in this 😭😭😭
Are you in 11th or 12th grade
True

This is the hardest part in trigonometry, lets be honest 😔
yaessss,no lie!!!
I totally agree with you 👍
Yes, for sure
I think its the application.
Not really if you get the hang of it
My teacher is trying to cram this into us in 3 days then we gotta take a test. Like hold up
try cramming into 1 hour
@@sophiafernandes4738 try cramming into 10 minutes 😭

Study pug ad:what ? Still searching TH-cam for math problems?
Me:YeS
Study pug ad:are the videos from 2006 really helping ?
Me:yes,yes they do
Study pug ad:you wasn’t suppose to say that ;-;
The fuck I swear I read your comment as the ad was playing wow
😂😂😂
I have premium but i watch ONE trig video on my friends laptop and I wasn’t signed in and I got that ad, I was like they can’t seriously be putting this ad right before a math video
🤣🤣🤣🤣🤣
I reacted with that same dialogue when that ad was playing lol
Thank you. Would it be possible if you could make an as level playlist with all the important content
Good idea
Clear explanations! Thanks Sir!
Thanks very much. Really helped more than three years at my school.
After this video, I could finally solve these equations. Thanks a bunch sir 😊💐
I won't even lie, I am doing CS at a rlly good school and I legitimately never understood pre-calc during HS at the fundamental level. With my weak foundation, I was always confused on small topics such as this. I am just brushing up on the small things that bothered me and oh my god why does it make SO MUCH SENSE now?? It's based on the unit circle!
Thank you for this! It really helps.
I have a math test in 20 min and i m trying to learn the entire unit since i legit slept through my whole class this past couple of months
did you pass
@@emilylaverty6708 obviously not
What happened
@@emilylaverty6708 i got a 73 which is terrible considering i was using Photomath and Mathway and Desmos😳
@@tylerl4768 next time study earlier I always go two units ahead cause sometimes my teacher goes fast
You helped me grasp the concept. Thank you:)
I’m convinced that most of my teachers just demonstrated their ability to produce the answers to the problems in their textbooks the way the books said that they were supposed to. I still find it hard to follow.
when your teacher cant teach but gives bad grades so u have to teach yourself
Thank you I love a bit of trig :)
Great video, thank you!
Have a test tomorrow, it really helps to get a refresher for a lesson we went over once days ago
😓😅

My teacher is the best in the world and I'm watching this just because it's part of my syllabus
i dont even get my classes in english so tell me why some random guy on internet explains the subject better than teacher who teachs in my native language, smh.
LOOOOL
Thank you for this tutorial
Thank you! Very helpful!
Thanks for this vid, massive help
Very helpful video + love the outro from Spanish caravan
Very well explained
He makes it so simple
Thank you so much this was helpful
Excellent explanation sir
Good work sir🤝
Very informative video
Thank you very much this is very helpful
Amazing 🔥🙏
Good video keep shining
Thanks it help me a lot
Thanks alot man good recap for me
Oh sorry you said A2 trig identities. I will do part 2 next
Thank u sir
bad
Thank you!
Yep I'm dead
same tmrs my math exam
Due to specific reasons I shall be ✨passing away✨☺️
Yall can do this 🕊🌞~ from a student who cant do this

TYSMMM I LOVE YOU!!!!
I'm here to know more b4 my teacher teaches...this video is good
Masha Allah very nice video
hello from Turkey guys ^^
and thank you for your service

Thanks, Sir
Thank you very much
In every video , pls leave some problems for us to solve ourselves 😁
thank you so much
Very nice video stay blessed
im yr8 and i am watching dis..
we r learning this..
Thank you
thank u very very much
is it just me who thinks this man sounds EXACTLY like korg from MCU movie. (the rock guy)
Thanks man, I love trig functions but sadly they barely appear in my career lol
I am in grade 7 but I understand everything he said. Great explanation
It is impossible
🤣
Best explanation ever🥹🥹🥹
Thank you so much 😀
Thank you 😔❤️
Examples of questions to prove that a value equal to a certain value using tan through demovres theory
thank you
No way this is as easy as the video makes it😱
I’ve just finished school, and now I get suggested this? Too late TH-cam. Too late…..
I find the usage of ≡ rather confusing because of its usage in modular arithmetic as congruency. For me atleast it implies similarity while not necessarily being exactly equal, like having the same remainder.
Apart from that, great video.
Thank you for this. You helped me better than my teacher lol
Nice
Does this even count as math at this point? I’m struggling to hard with Trig. This topic is especially difficult.
Good video but i hate trig so much 😭
Same and I want to major in Engineering lol
Relatable
I’m here cos my A math( in Singapore we split math into additional math-a math-and elementary math-e math-) teacher doesn’t have time to teach me
Great
Your videos are beautiful
hello sir , is this all required for cie pure maths 1
are you sure that its congruent and not equal?
i like your voice
Yah these identities are easy,, try deriving the Identity
tan (A+B+C); it's all complex fractions
I study in arabic i changed the language started studying in English as if that will make me less dumb
Takbir
Just a meme
😭😭😭😂
😂😭😭😭
Thanks- Sophomore in College
Masha Allah
In ex 2 i didn't get how you did the multiplication for (sin cos)(sin cos)
Pls explain and thank you.
Which part didn't make sense? If you are not sure about expanding brackets check out my video on that: th-cam.com/video/63oU-AIzTcE/w-d-xo.html
How is cos^2/cos^2 = 1 ? 🥲
Anything divided by itself is one.
🎉🎉
Sin²x+2sinx cos x + cos²x
1+2sin x cos x
Can we exchange the arrangement like
Cos²+sin² not sin²+cos²?? 🤔 Or it's false??
I want to know the answer
yes due to the commutative law. a + b = b + a
I was understanding at the beginning and then all of a sudden I lost it. It was like magic. It was like witchcraft. All of a sudden everything became so blurred. Absolutely witchcraft.
therfor left side will never be equal to right side
Still don't get it
U got enough ads?
Just trying to pay off my massive student debt 🤦♂️
@@maths.explained ye don't worry, I will have some of my own soon.
Странно, что они используют тету для обозначения угла. Мы всегда альфу и бету юзали
это именно то, что делал мой учитель математики, ха-ха
this guy is really good but your writtings must be a little bold
Why sin^2+2
Hello,you can contact us at oyugiochieng1@gmail.com for more explanation.
Stop reading comments and pay attention
I’m trying to understand English ,because i have to study for my quiz .
Em why am i watching this probly bcs im bored
One I couldn't solve in class but later when I finished the course..here
(cos x+ sin x -1)/( cos x-sin x+ 1) = sin x/( 1+ cos x)
You'd be tempted to clear fractions but I'm told that is not the correct procedure
only the Pythagorean theorem works..
sin ^2 x + cos ^2 x = 1 is all ya need to know
Why tf is this in a lucky block race in minecraft playlist??😅😅

You really need to get straight to the point and do less of unecessary talking
