Hello Sir, thank you for all the help! I wanted to ask for Q4 part (c), does the value for Y have to be a mixed number (5 2/3) or can I leave it as an improper fraction (17/3)? Thanks in advance 😊
Equation of the perpendicular bisector of PQ is required, so we will first find the mid point of PQ as the bisector will be passing through this, and then we will find gradient of the perpendicular of PQ, which will be reciprocal with change sign. Then we will use this gradient and the mid point to find the required equation. Hope its clear.
To equalize the ratios 5:4 and 3:7 multiply first by 3 and second by 4 you will get middle one equal and then can compare. Hope its clear. Also you can check new topic videos covering differentiation. ua-cam.com/video/P41ge7ecgEE/v-deo.html
@@ScienceAndMath Sir btw can u plz sepcify is there any other additions to the syllabus this year apart from Differentiation. I am bit confused since CIE website is not showing the right syllabus. And is this quadratic Eq. graphs part of Differentiation or is another newly added topic?? Plz guide me, I have to give Maths exam in 1 and a half week time.
In fact each question paper have one or two challenging questions but it all depends how you prepare for exam. Also it depends what is your target grade.
Very helpful. You just saved me 3 hours of my life, thank you!❤
Just wanted to say thank you for the time stamps 😊
Excellent sir. tq somuch sir. I have a small concern in grade threshold. In last they are giving BX,BY. May i know the meaning of BX,BY please

Thanks in advance 😊
It will work, but I will advise to give always answer in mixed fraction instead of improper fraction with the exception of probability questions.
MathsTV Understood. Thank you 😊

@@ScienceAndMath Thank you sir
Thanks sooooo much I have my Math prelim in two weeks and I got barely any of these right but now I understand how to do them!
In exam When writing on the diagram like question number 8b(ii) we write with pencil or pen
thank yo so much🥰🥰🥰,we got Maths on Tuesday and God bless you who are also doing the exams
Foor 30:49 , why did you put 8 as x? How did you find that? You didn't explain that part, an you please explain sir?
thank you so much for making these videos!! they're really really helpful and makes me understand everything.
Thank you sir❤❤
Gl yo everyone doing their math paper today lol!
You too thanks
I didnt understand the last question, how did u make that new equation?
Plz provide video time ref for your doubt, or question number with part.
@@ScienceAndMath question 12 (b) page 23
Question 2 b (ii) has to be the shittest way to find the center
I'm writing my paper 4 in less than two hours, any last words of advice? Haha.
*dies in fear*
Best of luck.
Sooo many ads..
I did not understand question 6b , can u pls explain how did u do the working?
He used the cosine rule bro
But how do you know the two angles are 58 from the angle at the tangent?
Alternate segment theorem.
Sir how did u do q1 part c part 1..why do we multiply 5 by 3 to get 15 and so on?
To equalize the ratios 5:4 and 3:7 multiply first by 3 and second by 4 you will get middle one equal and then can compare. Hope its clear.
Also you can check new topic videos covering differentiation.

@@ScienceAndMath thank you for informing 😊
Nadeem bhai bohot bohot thank you aapne bacha liya aaj
How do you know in 46:50 that that angle is 58?
he explained right after
The first question b) part is wrong .... instead of 4.5 u wrote 95.5.
thanks for the content but can you reduce these small mistakes pleasee
Are qn that's state stationary and turning points the same thing?
Yes
Sorry for question 5 d where does 11 and 27 come from
In triangle BCD, opp/ adjacent is 11/27 by replacing x=8. Hope the point is clear.
MathsTV How did we get the 8?
You can use pythagoras theorem to find The length of BD and use the sin rule for angle DBC
hello, do you do tution?
Yes, you can contact me on what's app

Hello sir is tracing paper is allowed in the exam for transformation ?
Yes it is allowed
Main instructions of the question paper indicates that tracing paper is allowed.

@@maaztv7561 there is no matrix only differentiation is the change
@@tanavmohan609 Loci is also excluded
At 40:56 why divide by 1000
For conversion into lit.
1:09:45 how can you tell the difference between the maximum and minimum point after differentiation??
If the second order derivative is positive then the point is minimum and if negative then maximum.
12:45 COE is (8,-7)
So helpful! Thank you!
I didnot get question n.o 1e from where you got 10?
It's not 10 corrected number is 30, plz check. And 30 in time duration in term of years.
Sir do we have any formula for simultaneous?
there is no formula jjust two ways elimention and substitution
Thank you very much!
Please reduce contrast slightly next time😬
Thanks for pointing out the technicality, we have already adjusted. Trying for better video quality in near future.
thank you very much sir
Most welcome
Sir, according to you what is the hardest IGCSE math exam paper? Kindly let me know so i can practice it for the upcoming maths exam.
In fact each question paper have one or two challenging questions but it all depends how you prepare for exam. Also it depends what is your target grade.
Thank you 😊
I have a question did the syllabus of maths in 2019 the same as the syllabus in 2020?
Please refer to Cambridge or your respective board website for syllabus details.
As far as I understand, they are very different.
An example would be Matrices, which was present in 2019, but not 2020.
