Thank you so much for commenting! I’m so glad to hear that your daughters have benefitted from the channel, please do keep in touch and let me know how they are getting on and if I can send any helpful links through etc 😁🙏🏼
you are amazing man and i cant express how much i thank you! i have learnt majority of the content through ur vids and now im getting grade 8 almost a 9 in my mocks THX SO MUCHH
The GCSE Maths Tutor Thank you for all the great content i went up over a grade in my mock to a 7, actually starting to believe I might be able to get a 8 thanks to you 🥰
Thank you your soo great my igcses are in a month i never fully understood sine rule and cosine rule but over the course of 2 hours i'm soo good at it thx
33:22 why does dividing dividing occur before square rooting.. according to Pedmas, squarerooting should occur later because square root is a type of exponent.
2:45 how come you swap the B and C? Is it necessary to do in an exam because wouldn't that change the equation because the opposites are now different?
Question and yep I know weird number but when finding an angle using cosine I did cos-¹(420²+69²-101²÷2×420×69) but it just ends up as an error. Do you or anyone know why.
Gemma Khan I will try my best for you! I need to record those via a camera so it’s a whole new venture going down that route but I will definitely do this during the half term 😁🙏🏼
You use the cosine rule to work out side and angles in non-right angled triangles (although can be used for right angles too!) when there isn’t a pair of opposite sides, in which case you can use the sine rule 😁🙏🏼
The question at 24:30, after finding the length opposite to 40 degrees, could you use Pythagoras to find the hypotenuse and then cosine rule to find the angle? Does that only work for this question as I did get the correct answer?
does it matter where you put the b and c after the a on the triangle because i put the b to a different place of yours and when you squared a it was like a 200 difference to mine so would an examiner still mark it right?
question, on your last question of the video, when you start finding x, why did you not take the minus, from the formula -2bccos60, should you not be timed by minus 1 if your do -2 x1/2?
please help when doing sine and cosine rule doing sin-1(ans) and typing in the cosine rule it’s giving me the wrong answers i don’t know what to do i have an exam tomz
Ariaa Here it is - ruclips.net/video/RMDl6zmuSF0/видео.html if you check the description or the geometry playlist there is also bearing with trigonometry 😁🙏🏼
Dont think it matters as long as it corresponds with the correct form of the question. If it gives you find the angle B but the formula is cos A, change it so that you are finding cos B. But in short, no it doesn't matter just make sure you rearrange if indicated by the question :)
From the exam board website: “There is no formulae sheet provided with Mathematics examinations. Students are not expected to memorise complicated formulae but may need to remember simple equations such as the area of a circle or volume of a cube.” This seems conflicting as I would class the cosine rule as a complicated formulae but as it states, there will be no formulae sheet given in the exams 👍🏼
2.45 is so funny lmao "I don't let the question dictate how I want to label it I label it how I want to label it"

Proper rebel
thank you for these videos they really helped, taking my first maths igcse today hoping i can pull through
got my second batch of mocks coming up this week and you’ve taught me so much - thank you!
same, good luck!
After next week for me :/...ya know....if you did higher aqa...uhm...mind giving me some revision tips... Ya know ;D.... maybe?
Thank you so much again. I wish you were my teacher!!! Please please please come and teach us I’ve got my whole class watching your videos 😅

You have the best intro music out of all Maths videos, Thanks for upping my mood at the start of the video
im in year 9, and im going into year 10 to do my mocks this helped me so much! THANK YOU
My father my mentor my everything I love you sir thank you very much.God bless you sir
Your videos have been so helpful, I have my exam in 30mins and am trying to do some last minute revision 😅
Was it y11 mocks
@shafie.1up no, they weren't mocks. I did cambridge igcse, which are done in oct/Nov
I have my mock coming up soon and your videos are so so useful thank you so much ❤❤
How would you know whether to use the sine or cosine rule? ++++ thank u so much for all the videos u do they are really helpful 😁😁
sine rule is used when you have 2 pairs. so an angle and length is 1 pair. cosine rule is used in other places
thank you this was honestly so helpful
Thank you your soo great my igcses are in a month i never fully understood sine rule and cosine rule but over the course of 2 hours i'm soo good at it thx
Thank you very much for these concise and succinct videos they make revising less tedious and more efficient.
Ty plz do whole course for gcse maths

THANK YOU SOOOO MUCH I HAVE MY PAPER 3 MOCK NEXT WEEK
My pleasure! Good luck with your mock exam 😁🙏🏼
Would you be able to relabel the A B and C in the actual exam? Or is that not allowed?
yeah dw
the one dislike is the guy who couldn't understand the video he makes it was easier to learn
what a wonderful revision ever. rthank you for your videos
COSTIE TV Amazing to hear! So glad it’s working for you 😁🙏🏼🙏🏼
very helpful, but on question 2 isnt the hypotonouse (sorry for spelling) supposed to be bigger
Great news! Which question? The only questions with right angles triangles the hypotenuse is the longest 😁
How do you know when do use the cosine rule or the sine rule?
Sine rule when there’s 2 pairs. Cosine rule when there’s 2 lengths and 1 angle.
12.29 why cant you just divide by cos a and then get a to the other side
Your intro always relaxing
You should do direct and inverse proportion

I recently discovered your channel, it's so simple and helpful.👍 Thank you
Thank you! This has really helped.
on the last one, wouldn’t u have to put a positive AND a negative or?
@grade9student ohhh okay thanks!
27:21 for this question for the last part i did sine rule and got 59.41° . Could i still get full marks?
rly useful, thanks.
plz do loci ,constructions and bisecting an angle(30° 60° and 90° ). Thank you😊

The question at 24:30, after finding the length opposite to 40 degrees, could you use Pythagoras to find the hypotenuse and then cosine rule to find the angle?
Does that only work for this question as I did get the correct answer?
Use trigonometry
thats what i did lol but its wrong
we can only use pythagoras in an right angled triangle
does it matter where you put the b and c after the a on the triangle because i put the b to a different place of yours and when you squared a it was like a 200 difference to mine so would an examiner still mark it right?
b and c can be written in either position but you should get the same answer! Definitely check your working out!
@@TheGCSEMathsTutor ye i think i have to put the a directly opposite capital A i dont think i did it last time. Thanks
@@ELLIPTICALWR i was about to ask the same thing lol

your videos are are sick
27:14 why can't I use the cosine Rule to work out x
cosine rule only applies to non right angles
I was wondering exactly the same as you
31:47 i dont get it i swear 1 plus 1 minus 1 gives u 1 why is it 3 helppp plss
because you’re minusinf a negative ( - -1) which makes it a positive!
