Find lengths AND angles using the sine rule (aka the law of sines). The sine rule is a method we use to calculate lengths and angles in non right angled triangles.
Almost forgot to inverse the sine function in one of the sums! lol! Overall, this was SUPER helpful. I have been struggling with this topic for months now, and you made it a cakewalk. Thank you, thank you, thank you a million times. May God bless you
thank you so so so so so much!! I’ve currently moved from doing AQA maths to IGCSE, so there was a lot more content in this syllabus but you made it very clear! thanks again ❤
Please consider teaching the following on top of what you've been teaching 1. Coordinate geometry 2. Transformation 2 Otherwise your videos are incredible
I have an important quiz tomr and I didnt understand this part 3:09 , could you please explain it? how did you get 6.19?? I got 10.54 I first did this 7/sin60 and then pressed "=" then did 8.08/sin50 and I got 10.54
When you have 1 angle given and 2 sides or 3 sides and asked to find an angle, use cosine rule. Otherwise, use sine rule. Tan rule is not part of the syllabus for iGCSE.
Did anyone get the same answer as the Maths Prof for the first triangle where we were to find the size of the angle? I got 37.6 degrees, but she said 35.8 degrees?
As l , l just need your Whatsapp number so that we can communicate . I want to pass , this year is my final exams . I just love how you teach thank u so much ma'am
your teaching is so clear and you really helped , thank you
I'm so pleased it helped! 😊
@@TheMathsProf can you come to my house and teach me
I definitely could pass o-levels by watching all these videos.Amazing explanation
Thank you , it is very clear and practical , easy to understand
I find your methods very clear and easy to understand compared to the methods that we are given in class ,thank you so much .

You make math easier your videos are so good and your a great teacher
Thanks ,you are an awesome teacher ♥️
EXCELLENT VIDEO
GOD BLESS YOU TEACHER
Thanks very much I always dreamt of being like Albert Einstein thanks to you my dreams are easily achievable
if i pass it my IGCSE its all thanks to you, i will be back in august
But really it will be thanks to all your hard work! 😉 Good luck tomorrow! 🍀
ITS AUGUSSTTT TELL USSS

Thank you so much
You are a life savor
So we only use the Sine rule when we know two angles or two sides right?
Wow ! Clearly understood .
You do it and it looks so easy fam
For that last question, is it okay to put:
Sin B= Sin-1(sin67/8 x 6.5)
B=48.4°
So that we can see that B=48.4° instead of 48.4°=B?
yes it is basically the same thing
Love ur videos
DO YOU DO ADD MATHS
I have an important quiz tomr and I didnt understand this part 3:09 , could you please explain it? how did you get 6.19?? I got 10.54 I first did this 7/sin60 and then pressed "=" then did 8.08/sin50 and I got 10.54
and i also tried multiplying sin60 by sin50 straight away like this 7/sin60xsin50 and I got 10.55. How??
Do not do it at a go!
Solve it step by step
@@Vincent-rr7hv u do realise my comment is 1 year old
thank you, so so so much! 😍😍😍
Thank you
how do we know when to use the sine/cosine rule? You did not explain this!
When you have 1 angle given and 2 sides or 3 sides and asked to find an angle, use cosine rule. Otherwise, use sine rule. Tan rule is not part of the syllabus for iGCSE.
I am typing the sums into the calculator but getting different answers to you....!
YES ME TOO

Beautiful in face in mind❤
Hi
Love it but sometimes l can't see your writing. A little bit annoying.
Ukr😭
As l , l just need your Whatsapp number so that we can communicate . I want to pass , this year is my final exams . I just love how you teach thank u so much ma'am
She's my Only hope to pass now 🫶
Described in such a simple way~ Just love it ❤
