[@user-gi3yr1gl7j]

you have no idea what a blessing you are to my life!

[@Saddafa-p1q]

great video. You are the real exam saver . whenever I do well in my class tests and mocks everyone keep thinking how do I know such hard stuff and surely all credit goes to you

[@senjitsu]

my literal saviour thank you so much

[@simirkaur5370]

The teachings are quite awesome. How awesome would be the teacher teaching too:) .....! your videos are greatly contributing in my effective conceptual revision.

[@TheGCSEMathsTutor]

So glad to hear that the channel is working for you! 😁🙏🏼

[@bpbkokkkn3885]

Thank you so much please continue with the hard work absolutely amazing you helped me more than anyone else I liked and subbed

[@TheGCSEMathsTutor]

bpb kokkkn Thank you 😁🙏🏼 that’s so great to hear!! Glad you’ve found it useful!!

[@jaheduddin7805]

Oh I was surprised when I could do this already. Wow that revision helped me a lot.

[@TheGCSEMathsTutor]

Jahed Uddin Great news!!! 😁🙏🏼

[@i4TheWinN]

Great video, a lot of stuff covered, just a spoiler to how tricky questions can get in GCSE Maths. Really well and thoroughly explained sir. When will you release my suggestion on how to estimate the area under a curve?

[@TheGCSEMathsTutor]

Thank you!! That’s great to hear 😁🙏🏼 I did your video for you the next day!!! Here is the link - kzbin.info/www/bejne/p2Wzc4SpncSjf68

[@Masowe.]

i am very happy i got the last one right allthough i calculated whole area then take away unshaded part. thank you for adding those hard questions

[@TheGCSEMathsTutor]

COSTIE TV Amazing news well done!!! Always love to see different methods being used 😁🙏🏼

[@msmith5189]

I thought of creating KZbin video of maths but I dont have any scope for you.Cause ur videos are more than enough to get a grade 9.Hope I will get it

[@christiangirltalk070]

Did u?

[@hashirkhan3633]

In the second last question u cna also just take the smaller trinagles area and then after finding 18 on the right angled triangle work out its area and minus them Makes it much easier

[@lensobenz9999]

Yh exactly

[@judeshekel9976]

How was finding the height to calculate the area of the triangle sin40 is that like cosine rule or sin rule i dont know at 3:33

[@revisionchannelsoyoudontge2999]

Hi sir, do you think this will come up in edexcel maths paper 2???

[@TheGCSEMathsTutor]

It very well could do! But then paper 3 has circle theorems and trigonometry too 😬🤞🏼

[@revisionchannelsoyoudontge2999]

@@TheGCSEMathsTutor oh I see fair enough😭 I’ll try my best to cram it all 🤙

[@MegaBanannaman]

problem at approx 30:40. I mistakenly thought AOB was a equilateral as I used circle theorem then solved the rest from the three 60 degree angles. I should of paid attention to the BOLD "DIAGRAM NOT DRAWN ACCURATELY" Just curious (question to anyone) am I correct in saying that AOB is a equilateral if it was drawn accurately ? Be nice as I am a 40 year old trying to learn math's again after a 25 year break! (or alternatively just tear me apart-whatevs)

[@yourlocalpostman]

Not necessarily because it's only 2 of the sides of the triangle that are formed from 2 radii of the circle. The 3rd side isn't a radius of the circle hence the triangle itself is isosceles. The diagram not being drawn accurately means that the 7cm provided in the question isn't an accurate 7cm

[@anitaa5811]

For the question at the time 30:28, why couldn't you do 360 subtract 50 to find the other angles then use the sine rule?

[@tahakarim1901]

You could, that would work perfectly fine

[@rayhaan7860]

sir the hardest question that was on here how many marks would it usually be?

[@bekind6869]

this is so helpful, thank you !!

[@saralammali3747]

I think there's a mistake at 27:10 as the equation for area of the sector is pi x radius squared x fraction of angle. Radius is 6cm so r squared is 36, not 12 like he wrote in the equation so is it a misktake or is there a step I'm not understanding? I haven't seen anyone else ask so Idk i might be wrong but some clarification would help

[@albinchoudhury7860]

he"s working out the arc so he can work out the segment

[@bigwizard807]

excellent video, thank you

[@Aaria7]

Thank you sir:))

[@ahmadalmohamad2610]

Thanks mate the video was useful and informative cheers

[@TheGCSEMathsTutor]

Ahmad Almohamad Great to hear 😁🙏🏼

[@lorigamingroblox3318]

could u make a video on matrices plssss

[@avni-g5179]

For the second last question why did you not do 36+18 and subtract from 180?

[@JP-xk3zu]

Thank you

[@TheGCSEMathsTutor]

J P No problem 😁🙏🏼

[@lolllhello7718]

Yesss

[@Yafama]

When I did the last question I calculated the area of the curved bit and subtracted it from the top triangle area. Even though I tried to be accurate I got 68.2 instead of your 68.5

[@memetris6971]

i thought i was smart but the second last one got me.

[@TheGCSEMathsTutor]

It’s a tough one! If it’s only that one that got you then you are clearly a great mathematician! 😁🙏🏼

[@lolllhello7718]

PLEASE REPLY IS ZERO CLASSIFIED AS A SIGNIFICANT NUMBER

[@TheGCSEMathsTutor]

Only when it appears after a whole number 👍🏽

[@lolllhello7718]

The GCSE Maths Tutor Thank you

[@lolllhello7718]

@GCSE Maths Tutor Can u show example please I’m still a little confused

[@TheGCSEMathsTutor]

Lolll Hello 0.34 zero is not a significant figure.. 3.04 zero is a significant figure

[@lolllhello7718]

The GCSE Maths Tutor Thank you could you make a short video on it please

[@christianscottmcwall9963]

please make a congruency video

[@ravex5169]

can someone explain how on the last question the height is 17.32

[@JC2007.]

The problem is not that I don't understand the question, it's moreso I can't do the question. I understand the working out but how do I develop this problem solving skill

[@JC2007.]

referring to the last few questions btw.

[@R3dStr1pes]

@@JC2007. spam past paper the exam board just reuses questions and puts different numbers so you dont even need to problem solve tbh
