Bro I really like you accent and you explained fantastically and this was really helpful for my upcoming math IGCSE examination

Multiplying Area (cross-section) by Height (extended length) will give us cylinder volume directly. (Instead of finding r-value)

[sofiakhan]

Sir, in your next videos can you give an explaination to all the steps you are doing. As some of the steps you did were confusing

[meahmadxx]

Thank you for that effort wish you the best❤

[samuelkaromo]

I AM VERY IMPRESSED AND LEARNT THANKS....

[rawanbahbah]

can u explain what is meant by the multiplying factor in Q6
this is the first time i hear this term

[crimsoniron]

For question 2, how did you get 0.56? On my calculator I got 0.44?

[risp]

in question 4 why so you use the angle 140 instead of any of the other angles?

[MrBruhMoment]

Just wondering on question 23 how did you expand the bracket with your n/2 to get 178n-n^2, just feels quite confusing to me.

[shafaykhanw]

Sir, for question 24 I don't quite understand how to use the formula (x+b/2)^2 +/- (b/2)^2

[sulaymantahir]

how did you get 27.75 for question 6b

[mohdzx]

For question 24 why did you take factor -Q and not x please explain at around 41:07

[KeanuTheMoneyMaker]

For question 13 how did u get 7/40 for the payment 3

[esmemyers]

For question 23 how did you know to equate the sum of the number of terms to the sum of interior angles. I dont know why they are the same because there are more than 5 terms in the sequence so how could all of th interior angles = the sum of the first 5 terms?

[Dgrking]

Hi, I have a question.... these formulas that you keep bringing up in the yellow boxes should be memorised or will they be given in the exam ?

[junedloriya]

Sir can you please re-check question 10 according to the formula it is wrong

[fxl_]

Sir for question number 17, how did you get 125t^-2? I didn’t get how u did that part, could you please explain if you don’t mind, ofc❤

[Vladnovavsg]

In questions 18 how did you get cos 115 for cos a

[sherlock_holmes]

For question 23 how did u get 180n - 360 for the sum of the interior angles at around 38:09

[vitofc]

in question 7 why do you divide 360 by 7?
