Oh my god you explained this so much better than my teacher,you are a blessing.

Yessss same it’s a lot clearer to me however when I do my calculations she wants me to put it in Degrees and minutes which is no prob. THANK YOU SO MUCH
HaHaHaHaHaHaHaHa!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!...
yes she is a blessing and thank god for that.
But not all teachers are bad at explaining!
You have no idea how bad mine is
Will u reply
After watching this i realized that my school should fire our math teachers. Buy a faster speed of internet and new computers so we can learn from you.
+tomlinzombie yesssssssss
I agree
Very true
big facts
deadasssss
guys if ur confused when to put sin on top or bottom, when you're looking for an angle sin is on top, when your looking for a side sin is on bottom of the fraction. Hope this helps
thank you!!😊
lifesaver 2 hours before the gcse
Best of luck @@grace_95
watching this 8 years later and it's probably saving my life

THE LOR OF SINES
Oh shut your yap
the lore of sine? I want to hear more about this lore :)
MrSkyaka deadddd 💀💀💀
I was preparing my salmon for cooking and thats what I heard but in my head it was law . Lol
@MA Granin lol she's very clearly australian
CAN'T BELIEVE YOU STOPPED MAKING VIDEOS. YOU WERE THE BEST MATHS TUTOR ON UA-cam.
yup
Julio profe is better
I think maybe she's dead
I hate when someone takes a break from UA-cam and thinks the person is dead, she isn't dead.
@@pianolessonswithbless879 no because they liked a comment which was a year ago so they're still active
You taught, in 10 minutes, what my teacher attempted to in an hour and 10 minutes.
My teacher explained it to is for like a minute and a half. And then wouldn't help us with it afterward. This lady actually cares about teaching.
Right!
I still don't get it, until I watched this video lmao
Correct yourself. It was an entire unit
pechannnnnn samee
I am so grateful for your simple and effective tutorial on the Law of Sines. Great work, Thankyou!
me too
This short video helped me understand trigonometry more than months of school
Same haha
lmao same my class does the same thing over and over again xd
Glad I could help you out! Good on you for taking it upon yourself to catch up and hitting youtube for what you needed. I wish all students showed that kind of initiative. You're going to be a superstar :)
Hey, I don't know if you'll ever see this but its literally 1 am the night before my test all the way in Pakistan lol and your video really helped me grasp the basic concept on this. Wish you did a cosine rule as well because you're really good at explaining. Anyways, have a good day!
I'm here after 11years and this has really helped me!
your explanation is so much simpler compared to whatever the hell my geometry teacher taught me
Same holy shit my teacher made no sense and was going 100 miles a minute
Yes! CDLI is soooo annoying. I don't learn anything, I always have to go to youtube
It should have been your trigonometry teacher.
Aryan Chaubey Nope. In our Geometry class we worked on this sort of stuff in February. In the book and everything
Aryan Chaubey they introduce it in geometry
Watching 11 years later and tomorrow is my math exam
SAMEEEEEEE I HAVE MY FINAL IN 9 HOURS
Watching this before mine too
real me too I have mine in 12 hours
You taught it better in 10 minutes than my teacher could in an hour, thanks!
so true
Haha nope! Just really busy unfortunately. I made the bulk of these videos when I was working part time cos I was studying. These days I have a full time job and a lot of other commitments, so finding a spare 10 hours to make one video is tricky! I'll try and post some more down the line though. Glad you like them :)
I appreciate what you done here. Good luck with your endeavors.
Thank you this should help me with my exam tomorrow
+joe grey You're welcome! Good luck with your exam :)
same plz like
hehe
joe grey sameeee
@@graceehastings8443 how'd you do
11 years later, the vid is still relevant and helpful. Thank you so much :)

As a primary school teacher relearning GCSE content to teach GCSE - this video was very clear and very useful! Wish there was one on the cosine rule too!
the dislikes are from math teachers
no joke, one of the best math videos ive ever seen, makes things soooooooooooooooooooooooooooooooooooooooooooooo much easier, literally saved me 3 hours
So glad for this, forgot half this stuff after leaving school. I've been sent back to college from my employer and your chanel has helped me so much brush up on a lot of mathematics.
This video actually teaches better than my teacher.
@@rzsteez3970 hows ur life 1 year later?
@Lorenz Panes Yeah sorry about that! It's cos I went and got a full time grown up job and ran out of time. Still hoping to find some time to make more of these one day soon, but it never seems to work out that way.
+vcefurthermaths Thank you so much! Omg never knew somoene explained Trigonometry much more clearer than you. THANK YOU!
ohhhh . hi . thank you for breaking down this example for me, I really didn't understand how my professor was teaching but u helped me. thank you
I feel like teachers nowadays give us too much unnecessary information without explaining them. Halfway through and I'm understanding this way better. Good vid.
Oh my God this is the best and easiest explanation of this on UA-cam. THANK YOU
You just saved me from failing a math test that I knew basically nothing about. You’re a lifesaver
It's my exam tomorrow and this video really taught me more than my math teacher could. i mean he's smart and all but he's really giving me a hard time
I know this is just the 600th comment but thank you! The accent also helps me because it's so calming and I can't wait to walk into class tomorrow to retake and ace a quiz that I absolutely failed today
Why did she stop making videos :/ I agree with ur comment, her accent and way of teaching was so perfect..
my teacher thought us this for a three hours in total and he didn't made sense. Thanks for the lifesaver!
*TODAY I WILL BE TEACHING YOU **_SINE LOR_*
Are all Australians good at maths or something? What's in your "wata"
I know, they're just lying about their prime minister being an idiot to keep Americans and others away.
Jacob H Hey that's not true. Don't just say that -.-, I am an aussie and a lot of time people aren't proud of our pm.
Mc Lovin' Malcom turdshit!
@@whyareyoureadingmynameyouf4639 LMAO YOUR NAMEEEEEEEEEEE
Using a right angle to determine which equation would solve my unknown is a time saver i hadn't thought of.
My teacher never taught me that third scenario. She put it on the exam anyway. Thanks, much love.
All though you give a good explanation in the beginning, you don't explain how you get x=5.76 very well. I believe if you breakdown that piece of the puzzle, then some of it will become clear.
terence brown although I’m 5 years late inverse sine is when it changes to the other side of the equal sign
Thank you for making this clean and simple! I really appreciate it! Great work!
This whole process took my teacher 45 minutes to teach us... you compressed that into a 10 minute UA-cam video and I learnt more from you than my teacher.
11 years later and your still saving me
Trigonometry has always been my fault in maths, you just changed that. You are so much better at explaining it. THANK YOU!!!
THANK YOU, they didnt really teach me this in school for some reason. and this year apperantly we were supposed to know it! You are a life saver! :D
11 years later and this is helping me for my end of year exam tommorow.
Thank you so much , I didn't understand nothing about the chapter until I saw your videos 👌🏽 , You have a new subscriber right here
GOD BLESS THIS WOMAN!!!!!!
Excellent video! I went from having no idea how to do this to knowing it very well. You taught me in 10 min what my teacher could not in 2 days. Thank you so much!
This 10-minute video taught me what my teacher couldn't in two hours
THIS WAS SO HELPFUL. Thank you!
Came here to refresh my knowledge. Watched it, I understood everything, had no problems following and it came easy through my head. Nice job!
the lore of signs!
Thank you so much i have a test tomorrow and it feels so good to finally understand what hes been talking about all week
I’m genuinely grateful for this video- THANKS!
Thanks that's so helpful for the longtest tomorrow
Thanks for the help, and love the accent.
Glad your found it useful! Thanks for commenting :)
You're soooooo welcome! Glad you liked it :)
Hi my name is JC and I'm from the philippines and this has helped me with my periodical test tomorrow on march 9 I'd like to say that you taught me better than what my teacher did I learned everything I needed in this video alone thank you so much ^_^
Pogi si Jc Juan
Musta jc from 8 years ago?
wow.... what a great explanation! Understood it soo easily! Thanks! I hope to see more of your easy and understandable videos! :))
This makes math so easy
This was SO helpful. Like seriously.... why dont schools hire people like you.
on the first equation that ends around 4:49, i keep getting the answer -6.26....
i dont have the fraction button so i am dividing, anyone know how to fix this?
In case anyone else is having this problem:
It looks like your calculator is set to Radians (does it say RAD at the top of the screen?). Since this equation is using degrees you need to make sure your calculator is set to degrees (DEG). Good luck!
@@HDCalcs omg THANK YOU i been tryna firgure what was wrong w my answers
My teacher is dumb and have a test tomorrow this is helping me very much thanks a ton. Btw the way you do your X's are weird but make them look sick
I'm pretty sure everyone uses swirly X
I didnt know why until I saw
2×x×3 or sumthing like that
:P
@@mse5842 ye everyone uses curly x
I'm learning this just for fun now ... the teachers I had in school were smart (I guess) but clueless as to how to explain these concepts to another person. Thanks
Watching this video after 9 years but...
It really helped
Video came out almost 10 years ago and its still helping people. Thank you!
So many Australians! OMG I swear every maths video I've watched has been done by an Aussie.
Gotta GCSE tomorrow, may have just saved me. Thanks a lot!
you dknt understand how happy i am we have been on this topic since november its now january and i finally get it i am beaming with joy
This literally taught me how to do the sine law in 10 mins, something my math teacher couldnt do in months
Watched this during the test
idk if it’s cuz you’re australian, but your math made so much sense and you made it 10x easier!!
thank you so much i was lost until i found your video. You make it so easy.
Did you do this on Powerpoint with a tablet mouse? Love your graphics
I put 9/sin30xsin94= 28.2 why?
+vinicius caetano might be the way u punched in the numbers
I'm glad you found it helpful. Thanks for watching :)
this helped me so much, i didnt understand my homework at all but you saved me!! thank you
I love maths, because of you. Alhamdullilah..
Alhamdullilah😊
8 years later still learned it perfectly in 10 mins ty
Watching this eleven years later for my math exam tomorrow. I don't know how to thank you
Learnt this this morning for my maths GCSE and It came up! Thank you
Thank you so much, for whatever reason I as a junior still can’t retain information easily, however this video really helped! Thank you very much!! 💟
It's such a shame that I ended up with a C in trig. One of my problems in that class was that I did not really understand my professor due to her accent and the way she would over-complicate explanations of certain concepts. I was also kind of intimidated to ask questions during class because I felt like others didn't have the same problem. Fortunately, I'm in precalc and so far I've aced my exams and quizzes by doing my own research outside of class and my textbook. Thank you for this easy and sensible explanation!
Much easier to understand than many of the other videos I have watched
This taught me better than my math teacher, thank you
You're doing sin95/sin10. There is no "sin" before the 10. It's just sin95/10
Hope that helps! :)
Please upload :)
thanks for commenting! I'm glad you found it helpful :)
Excellent instructional video.
Really helped me remember the concept I learned 10 years ago but have now forgetten.
Hi there. I really like this video (and your others for that matter). I am a maths teacher in the uk and would like to make some short revision videos for my students along similar lines. I was wondering... what software are you using to record/edit your videos? And are you using a tablet to draw on? Many thanks! Stu
0:05 "The Law of Sines can only be used for non-right angles triangles"
This is not true. It's almost always easier to use pythagorean theorem and trig functions to solve right triangles, but the Law of Sines still works...
Hard to express how fucking good this explanation is
Legit I was struggling on this in my foundations 20 class for 3 days and this explained it so much better than my math teacher did ngl
Learning Off UA-cam Because The Education System At School Is Broken. #BrokenEducationSystem
Yep!
lmaooooooooooooo am i the only one that realized the method is wrong
its supposed to be 10 x sin35 / sin95
NOT 10 / sin35 x sin95
which part of the video are you looking at?
@@niz32iqbal 4.47
Watching this the morning before my test. Understanding it better
Amazing video, only comment I want to make is that the angle I calculated around 8:50 in the first part was an odd choice given the visual representation. I thought I did something wrong when I worked it out before you, visually it does not look like a 94 deg angle, rather it looks less than 90 deg.
I wish my teacher was this gentle, mine talks so fucking fast Costansinhypadjacentoppositecscseccot, okay guys?
LAWr???
11 years later and you are saving me
boy u are wonderful explaining this so comprehensively.
i would kiss you but thatd be impossible and weird
It blows me away to see how crappy my school system is when it took me over a week to barely understand this, and I watch this 10 minute video and I'm now a master ;)
Thanks. I literally have never worked with sin before and its gonna be on the test im taking tomorrow. 8 hours away actually, I should get to sleep soon. Thank you for your help stranger on the internet!
Was stuck with problems. This video helped the heck outta me.
