3. Could you start the problems yourself?
let us know what you have tried, im sure people will want to help, but few would be okay with doing it for you
4. I require some assistance with 2,3,4. with 3 i think it is either b or f or both not sure though. Thanks
5. For question 3- For (b) i can show its less than for any n but not equal so not sure and same for (f) can show its greater than but not the equal part.

So what did you do for 3 (b)?

b and f are correct and the answer is 4 - the 'or equal to' part is unnecessary but used in all of them so you can ignore it - the statements are still true

what have you tried for 2&4?
8. I just tried tons of numbers for small n and large and always worked but cant find an n that it is equal or a way of showing mathematically that they are

Does this make any sense to you?
10. Yes, where from there?
11. oh and then u get rid of 1 and then get 1/n
12. So then B is correct right? what about f

Difference of squares?

what have you tried for 2&4?
Yes for 2 i got 6) so L=1 and not a clue how to do 4

you have to manipulate things for 6 until you get something that HAS to follow the inequality
i.e. a higher denominator and lower numerator always guarantees a lower number

Difference of squares?
So would you agree that it is b and f correct for q3?

How did you get 5 though?

How did you get 5 though?
Found values for which absolute values vanish and split into three intervals and then tested each one

Yes.
21. (Original post by EricPiphany)
Yes.
Great thanks Have you had a look at q4? I am currently doing it, also did u get same answers for 6 then?
