Hello isn’t question 12 misleading in the sense its asking for SA but has m^3 as the answers unit

[Dev_Builds]

I have another method for Q7. You could subtract the two equations which yields the distance between the curves at any x coordinatione. Then minimise it, giving x=5/6

do i need to know derivatives or integrals of trigonometric funcitons for TMUA ?

[moono]

For question 20, isn't 15<k<20?

[rbj]

for q16, can we not just take x^-5/3 out of the equation and solve from there or does that mess up something with negation

[MMSaths]

For the last question, it wants the values of x for which it has 4 solutions. But you gave the range?

for question 6 why do u divide 10/11 / 2

[iden.r]

hi i cant find the vid u mentioned in 19:40. nice vid btw

[anonymous]

how can you tell in the exam if a function eg y=x^1.8 will negative for any values of x or not

[urvii]

this is probably really stupid how is the gradient 6x = 5 in question 7
