This video is a tutorial on Sine and Cosine Rule. Please make yourself a revision card while watching this and attempt my examples. Straight away then move to my video on Sine and Cosine Rule 2 - Exam Questions 18. This video is for students attempting the Higher paper AQA Unit 3 Maths GCSE, who have previously sat the foundation paper. Explanations are aimed at being as simple as possible and so students who previously did the Foundation paper can access. They would also be useful for students who have always sat the higher paper. www.hegartymaths.com www.hegartymaths.com/
My teacher took about 3 months to teach me this and I still never got it. Watched this video and learnt it perfectly in 20 minutes. Thank you

Restaurant Pandemic 😩😩😂
bruh understandable
*Laughs in Coronavirus*
i wish i did gcses back then. Theyre killing us with all this memorisation i swear
@Restaurant Pandemic it's really not that hard to remember
I don't know about anyone else but this video is magical it is like a revelation. Everything can be understood and each step is so beatifully explained. Well detailed. Best mathematics video
@AWhiteBlob yes
@@otsebby5440 this is so funny hahaha
Ifkr
The only problem for some students is remembering it afterwards [along with all the other parts of a maths syllabus], plus another 5 or 6 subjects which need to be mastered for exams.
Teacher's been trying to teach our top set class this for a whole year, no one understood it. I watched this 20 min vid once and I know it all! Thanks a lot!
***** same
My teacher taught my class this in one day somehow
Good luck! Glad if I helped! Mr H
You helped alot thanks

I'm homeschooled, but it's difficult for me to learn on my own and I always end up having fights with my Dad when he tries to teach me, plus my exams are in 3 weeks so thank you, you're channel is helping.
How did it go if you don't mind me asking ?
Have a like just for the name
it’s been 5 years, how did it go?
HI there. Really delighted if I have helped you, Best of luck revising and good luck in the Unit 3 on Monday and if you think the video is good please share with family, friends and school. Best wishes. Mr Hegarty
Doing my GCSEs in the next couple weeks, these vids have took me from a grade 5 to a 8, and still some time to improve
@@danielhastings1471 u watched his videos and past papers that improved ur grade right?
@@birdie7344 Certainly did, finished my last gcse today
I just kept getting syntax error every time time I followed the steps
You're such an amazing teacher! I wish my maths teacher was like you, but he constantly throws tantrums and screams at us, throws scissors around and scrapes the smartboard until there are huge marks left on it, bullies the students and makes them feel stupid, dOESN'T TEACH WHATSOEVER, you get the point. Anyways, I would give anything to swap him with you, Sir! You have a talent for teaching so efficiently and precisely!
Oh how I miss the days of the formula booklet.
wow you made me an expert in 20 mins

Is your calc in radians mode? It must be in degree mode and say DEG at top. Change in mode settings
I'm taking a police radar/Lidar instructor course in April. I gotta be honest. I am 100% math illiterate. I have zero math skills. I've been studying for 2 weeks now on CZcams. You are the 1st instructor to break it down nicely. I have to do cosine problems for this course. I'm very nervous. Thank u for making this understandable. Also. I have hardly any algebra experience and no trig experience.
2017, we don't get no formula booklet. Wish me luck.
+Robbie | Robster I'm taking my exam this year so I just get it, good luck with that
outerspacelucy It's so dumb D: You're so lucky haha, Good luck :)
Robster In my country we still get a forumula sheet that tells us all the sine rule and cosines rule, curve surface area of sphere and cone, -b+-√b^2-4ac /2a, trigonometry double angle forumulas, trigo addition forumalas, trigo identities, 1/2abSinC.
Tatabusa Express for edxcel math ?
how did it go??
What an amazing teacher. Thank you SO much sir. You're literally the best Maths teacher I've ever seen :)

"I've Ever heard" is what you meant to say, because you have never actually seen him, i think you need to head over to the grammar section of youtube
Alex Entwistle sorry😂
Aisha that's à wonderful Teacher u'er Amazing 😘
You haven't me ms.hickey!
i just wanted to come back here after receiving 100% on my math test to thank you for your help! to anyone doing trig geo or scales I recommend this video specifically and the whole channel is amazing!
I'm in Engineering Mechanics with Statics - Vectors. Hadn't done this sine/cosine rule crap in 8 years. Professor just starts doing this stuff on the board like we were all pros at it, I almost hyperventilated I was so panicked! After just this video, all the homework problems are a BREEZE! You've saved my life, sir. Thank you so much!!
Thank you so much, your videos are fantastic and a lifesaver for so many students including myself. I tried so many different different GCSE Maths tutorials on youtube and non of them are clear and concise as yours.
You are the best under the sun, I'm in a Zimbabwe college and they teach, I have been watching your videos for like eternity

Very well laid out and you got straight to the point. Thank you sooooo much! Feel a lot better about my exam now!
Jennifer. Really delighted if I have helped you, Best of luck revising and if you think the video is good please share with family, friends and school. Best wishes. Mr Hegarty

I'm calling it a success when you get from D grade to an A grade in 3 weeks. Thankyou so much for these videos on maths helped me out so much!!!! just goes to show that my teacher is not the best at maths
650k stressed students watched the video for the same reason...
Thanks so much. I have never done this in lessons and feel left out when its been discussed but I decided to be brave and come on here which i subscribed a long time ago. I really understand and it seems so easy. Thanks for doing this. You are a hero
I’ve watched tutorials 15 through to 17 and I want to say I find your videos fantastic and easy to follow. Thanks for your time and your help!

You're the best math teacher on this planet. I never understood these rules but you explained them so well. You're just amazing!
I'm not even studying math. I've actually not studied for years and have no need for this lesson. That aside, it is so well explained that a man like me who isn't practising for an exam can pick it up quickly. I just learnt a but for fun. What a simple and easy to follow vid. Thank you
Thank you very much sir for taking your precious time for making this video. This helped me a lot ..thank you very very much sir!

The new GCSE has no formula booklet :(
For edexcel too ?
You have to remember all the Formulas???
You’ll get the formula for some like the volume of a sphere
Suria Begum the most it’ll say is one, n it’ll be in the actual question
I dont even have gcses, let alone a booklet
you are my savior! ive been struggling with the whole of trig since year9 and now i understand all of it, 2 days before my exam!thank you so much :)
What a loveley comment. :-) Really appreciate the positive feedback and you think my work is helping you!! Check out my website hegartymaths.c.o.m. for loads more help. Best of luck with your maths. Keep up the hard work. Mr H
You are the best teacher ever😆 I finally know how to do my sine and cosine rules question ,Thanks so much!😊
U the best
Wish I’d have found these videos earlier not a day before my paper 2.. hoping I can push my 6 up to a 7
Ha I don’t even have my results yet for the first one, any way good luck tomorrow.
What a lovely comment! Thank you :-) Really happy to hear the videos have helped. Keep up the hard work!!! Start using the new website hegartymaths.c.o.m. for loads more help and best of luck! Mr H
Been trying to understand this for the past two years. Thank you so much sir, I wish you were my maths teacher.
Literally the day before my test-
Anyways, this really helped
are u a comedian hegarty? the Jim joke u used twice was Fucking classic
+Caolain Hession exactly lmao
i have my unit 3 exam tomorrow morning and i've slaved over maths for sooo long and i'm just praying for a C
i'm absolutely gutted that i've just found this channel tonight, i've learned more tonight than in the passed year with my teacher, even now I completely appreciate all the time and effort you must put into this channel
We had 5 different teachers when we were being taught the sine and cosine rule and all of them taught it in different ways! In 20 minutes you have made this so simple and understanding. Wish you were a teacher at my school!
how do you put the calculation into the calculator (14:51)
Sharon Pious you click the root square and then there is a ans button next to equal sign and then press equal to sign . That’s how you get the answer
This is brilliant thank you...anyone ever said you sound exactly like Simon Lowsley in Waterloo Road? 😂
Charlie J The explanation was clear men thanks a lot
Thanks to you for having that gratitude towards us. This is a topic that I never dis in class, and I'm sure I wouldn't get if I did it in class. The way you explain it is fantastic.
This dude is literally my life saver.
Great video! Only, I'm typing in the formula into the calculator and getting different answers, where am I going wrong?!
Write the first question on the cos as 12power2 +17power2-[2×12×17cos(47)]
Hate how next year the sin & cos rules are not in the formula booklet, just one more thing to remember 😢
enjoy A-levels now lol
@@SlushSnail now YOU enjoy a-levels
@@wafa1606 I hate karma lol 😢😢😢
This is the best explanation I’ve ever gotten on the cosine rule and sine rule ever. Thanks, you’ve just saved my life 😌
helped me learn this all on the night before the exam, thank you!!
is it bad that my calc paper is tomorrow and i havent revised yet
no, you gonna be fine, WE ALL BELIEVE IN YOU, U GONNA GET A***
Yes, but neither have I :0.
bring it on. I've got it as well
+TheSilentRoar it's ok lads we all gonna pass
leaked paper on my channel
Who is watching in 2019?
2020
OH MY GOD *THANK YOU!* I've been struggling with this for _ages_ and my maths teacher didn't even tell us about flipping the sine rule upside down or the different version of the cosine rule! Now I finally understand why I kept screwing up some of the past paper questions (I now know I needed the other version of the cosine rule not in the formula sheet). THANK YOU THANK YOU THANK YOU!!!! I'm definitely subscribing to you now!! :)
Your videos are brilliant and really useful. I'm really using this video as a refresher, but your video on Circle Theorem was incredibly useful and taught me what my teachers never really managed to do. Thanks, I'm very grateful!
HEGARTYMATHS interesting comment
TheRuinedUniverse It has such a deep meaning. It demonstrates the empty feeling we all have about life.
I like HOW he SLOWLY goes through every problem other than my teacher....
Its just so sad to see someone see others INCLUDING me struggle through these things that should take TIMMEEE...
Math is NOT a quick process. Its a slow and tedious one.
To a smart brain anything seems easy☺
@@akshatkothari2705 Well everyone does not have a smart brain😒😭
you have no idea how helpful you've been to me! you're amazing!
Best teacher possible. I never understand the sine and cos rules before watching your video. Tomorrow is my exam and definitely I will answer everything because of your teaching. Cheers
That moment When I learn more from u than my teacher
Alan Sabu I need your urgent help. Get as many people as you can to vote before 10am Tuesday morning (try to get 5 votes at least). We're losing :-( We need the votes to get us through. Thanks loads. Mr H :- ) www.virginmediabusiness.co.uk/pitch-to-rich/start-up/hegartymaths/
Anyone failing?
most definitely
Spent about 3-4 weeks in class on this and didn't understand it once, watched your 20 minute video and I can now answer any questions that come up on this topic. Thank you soooooooooo much :D
You're a math KING 👑. thanks for the PERFECT TUTORIAL.👌
Very welcome! Best of luck and remember to check out hegartymaths.c.o.m. for loads more help! BEst regards. Mr H
Thank you so much! what has taken a couple of videos from you has helped me pass my GCSE!
this guy is the greatest math teacher of all time
This is fantastic ! I'm going to be watching your videos for the next two months until I had my maths exam , this has made my understanding so much better :) thank you
This was great! Helped me out a lot. I had forgotten how to use the sine and cosine rule and watching this video, you explained it so well! Thanks!!
whoever you are i just want to let you know u r a good teacher. if only i hv been taught like this.
Thank you so much!!!! I appreciate the color coordination to help with guiding. Also, the explanation on when to use cosine and sine.
It took me 4 minutes to understand this. Something, my teachers explained for months, still, I couldn't get it. Some people are natural born teachers, they chose simple words to explain and make Maths look so easy. Others teach just for the money and to rush and complete their syllabus. Thank you
Thank you so much man,I cant express my gratitude.I have my test tommorow and I was scared the whole of last week how I was going to learn these 2 rules and apply them.You really are an amazing math teacher..
You've made this seem really simple by the way you have explained it, thanks for helping me
GCSE maths exam tomorrow you are a life saver Mr Hegarty!
Thank you! I saw a question of this on my mock exam paper and from that point on, I was baffled. It was until I saw this... I can now master Sine and Cosine Rules skills! Thanks again, Hegarty! I subscribed and liked! I will check out your other videos too!
Great tutorial. I'm doing HEFC's to go into Primary Education and this has really helped towards my final exam. I feel more confident now! Thank you!!!
Hi there. You are most welcome and thank you for your kind words. Best of luck in your forthcoming exams and please share my channel with family, friends and school to help others. Best wishes
Mr Hegarty
i have had many math tuition teachers who were very good, but you are the BEST!!!!!!!!!!!!!!
Thank you so much... i started doing higher now and it's a few days left for the exam and video 15 and 17 had made it so much easier to understand
You don't understand how much you've helped me! thank you so much your videos are the best!
You are the most helpful teacher ever!
