There's not too many channels that go over specific questions like this and with simple instructions as well, thank you.

how did you revise did u just watch all of his vids and make notes?i have mocks in 2 weeks and im aiming for a 6 or higher.can u plzz help

@@arinahsajid637 what I did is watch all his video but the most important thing to do it not make note but acc do the questions with him than do once you feel you understand it and get the gist then answer the rest of the questions in the video by urswlf then watch him do it and see if you got it right if wrong correct and try do it all again by yourself

Ive got a question I still need help with! y is inversely proportional to x^2 . It is given that y = 7 for a particular value of x. Find the value of y when this value of x is increased by 250%.

[@qadeersadiq2531]

I still don't understand directly proportional sir I an trying really hard but I guess I'm just too dumb 😿😿😿 but your videos are amazing BTW I just guess this topic is not my strongest point

[@zgamer3268]

can someone explain why the formula is y=k/x(power2) when i searched up the formula for inverse proportion it does not say anything about the power 2

[@TheGCSEMathsTutor]

If it is inversely proportional to the square of x then the formula will have to be amended to suit this 😁🙏🏼

The surface area of a sphere is directly proportional to the square of its radius. A sphere of radius 10 cm must be increased to a radius of x cm if its surface area is to be doubled. Find x. Please solve this question for me. I shall be grateful

hi, yes this is way too late to be useful for you but maybe it'll be useful for someone else - answer is 14.142

[@eirinieparaschidis2607]

For the 3rd question, couldn't you just write h=60/0.5 x sqaure root of t ?

[@TheGCSEMathsTutor]

You could but you shouldn’t ever leave a decimal within a fraction for a final answer 😁🙏🏼

[@diegomandragora4327]

​@@TheGCSEMathsTutorNooooo. Wrong answer! We can't just take something out of the denominator and do multiplication with it at the end.I know it might looks like as if that implied multiplication between 0.5 and root t has has just gone vanished, but we must not forget that our numerator has effectively doubled. Please edit the comment! 😮

[@christianscottmcwall9963]

for the last question can you simplify it even further by square rooting 100 and 9 to make 10/3xsquared

[@kirstenlillie2918]

No, because then you would have an equation for the square root of y, not y! When we're simplifying a fraction (dividing top and bottom by 4, in this example), we're not changing the value of the RHS of the equation. If we take a square root of the RHS though, then we must also do the same to the LHS. I agree though, that it is very tempting :) Mathematicians love to spot that kind of pattern and it is certainly true that root y = 10/3x^2.
