YEAH.. it is very helpful for maths and somewhat for physics too.
like for physics it covers kinematics , dynamics and many other except electronics and waves.

for b(ii), use the difference method...
find the 1st 5 terms then take out the difference. like this:-
4 9 16 25 36
5 7 9 11
2 2 2
2nd row is the diff. btn the nos. in 1st row and 3rd row is diff. btn nos. in 2nd row. and since its a quadratic function (ax^2+bx+c)
2a=2, so a=1
3a+b=5, so b=2
a+b+c=4, so c=1
the function is x^2+2x+1
got it?

got it
