The best youtuber teacher for IB papers for real. Just incredible simple and understandable explanations and attention to detail to maximize the points. Thank you Ginger Mathematician :)

Hello! I have a question for number 7. I completely understand your method of approach..but I was wondering, to find the area of this large triangle (which is right-angled), couldn't I find the area by taking the base as GI (p+6), the height as KI (q+8)...which would give me 0.5(p+6)(q+8)...would this also be correct?

[@GingerMathematician]

Also works :-)

Hi! for question 6, why isnt the rounding for the side 56.49 and 82.49? I though when a number had .5 it was rounded up?

[@GingerMathematician]

Hi Leleu because we are looking for the bound. You could have said 56.499999999... so we take 56.5 and then say everything below it, easier to write down :-)

Hi Ginger Mathematician, can you please make walkthrough video to paper 43 of Oct Nov 2021 since it’s released

[@GingerMathematician]

Not available on Cambridge yet... I assume you've checked PapaCambridge?

[@xtremegamer8351]

The paper is available on IGCSE reddit

[@xtremegamer8351]

@@GingerMathematician did you find the paper on IGCSE reddit yet?

[@GingerMathematician]

I saw the thread for the 43 paper only; I'd prefer to get them officially from Cambridge and they come out on the 18th January 👍 I can also then see the official Grade Boundaries

at question 6, how could u come up with angles 107.5 and 102.5? I didnt get that

[@GingerMathematician]

Because it is rounded to the nearest 5 degrees, you need to think about what are the upper and lower bounds that round to 105 degrees 🙂

[@GingerMathematician]

Hi there, see my previous reply 🙂👍
