I can do if you want! Shouldn’t take long, nice and quick to make a video on this but you won’t need it for the GCSE! Regardless.. I’ll never turn down an offer to prove the quadratic formula 😁🙏🏼
DaCatNextDoor One question on this came up as the very last question on one of the exam boards, and one of the others came up in a mock paper for one of the other exam boards.. so it could happen!! It’s a very unique question though I must say but I wouldn’t completely rule it out 😁🙏🏼
Thanks for sharing! I posted a short video on deriving the law of cosines, It should apply for all angles (acute, obtuse, reflex, negative). Hope to get your thoughts.
sleep Absolutely!! It’s a very unique question that could only come up once though but still worth knowing as the process will help with geometric proof 😁🙏🏼🙏🏼
15:41 since we don't have any values of lengths, couldn't we also use TOA since we "have" opposite like we have the hypotenuse? I don't understand how we could know to use COS.
for the area of a triangle you mention that the base of one of the right angel triangles in that one irregular triangle has base "a". wouldn't it be "a-x" as it is not the full length?
This is just a different way of looking at it if you were the split the triangle via a different base, it’s not really necessary but it can be done other ways 😁🙏🏼
I’m calling it, one of these is gonna be the last q on paper 2 of 2022 edexcel paper.
That wouldn’t be nice 😰
want to bet?
Nvm I was wrong
@@finnrattray great news 😁👏🏼👏🏼
So interesting, could you prove the quadratic formula?

Hey to prove it complete the square for you.
Question: would we get asked about Proving the sine rule, the cosine rule & area of a triangle using sine in the papers?

Awesome flawless explanation SIR!!! Salute to such a great teacher
What awesome feedback! Love that 🙏🏼 thank you so much for your kind words, so glad to hear it’s useful 😁
Sir do you take online classes?
@@shabadkaur6465by that do you mean do I deliver tuition lessons?
@@TheGCSEMathsTutor Yes sir!
@@shabadkaur6465 I’m currently fully booked unfortunately but if you follow me on IG I’ve got something coming up in a few weeks/months! 😁👍🏼
Clever. More words will merely spoil the whole issue.
Sir for proving the area of a triangle do we just assume that the perpendicular height bisects the side CB?
Yo, im almost ready for Maths exam on the 13th, just curious when u will start the revision lives and vids before exams
Great video sir good job!! Really well explained!!
Thank you Abdallah 😁🙏🏼

thank you literally so much
hi sir could this sort of question come up in the exam ? eg,, prove this triangle using sine rule?
sleep Absolutely!! It’s a very unique question that could only come up once though but still worth knowing as the process will help with geometric proof 😁🙏🏼🙏🏼
Great video 🙌
Sophia Thanks!!! 😃
how about proving the quadratic formula and pythagoras
Thank you 😊
When will we need to use this
15:41 since we don't have any values of lengths, couldn't we also use TOA since we "have" opposite like we have the hypotenuse? I don't understand how we could know to use COS.
Thank you
for the area of a triangle you mention that the base of one of the right angel triangles in that one irregular triangle has base "a". wouldn't it be "a-x" as it is not the full length?
crazyy how this is gcse
plz explain the triangle at timestap 5:29 too
This is just a different way of looking at it if you were the split the triangle via a different base, it’s not really necessary but it can be done other ways 😁🙏🏼
Ayy thanks
My pleasure! 😁
is this further maths or normal gcse maths?
Both
Higher maths paper
is this for further maths?
gcse higher
Is this on the spec
It is indeed! 😁🙏🏼
Do need to know this for AQA
apparently it's on the spec
damn what a video
theres noi way theyre gonna ask u this
