I need to look at it in detail ( I just came back from holidays a few hours ago) but I think it is correct.

My solution is essentially the same, I just show more steps for the benefit of students, and I have used IBP which is essentially a variation on what you did at the end.
Good to know. Thanks!

You said that the solution was correct

but the question was wrong...so surely the solution is therefore wrong for the intended question?

if that makes sense...it probably doesn't

15. Back again and stuck again lol. Right idea or no? Idea was to find where they intersect and work out distance from centre to there or something

16. For the extra did anyone get...

I agree with the first three parts, for the last part I seem to be getting
Spoiler:

0 - dont you essentially have L - 9*(1/9)L?

Not certain though.

It could very well be, where did the 9(L/9) come from?
Spoiler:

i used the original summation and deduced L/3 and 8L/3 to get -2L.

start by drawing the relative positions of two circles and their common tangents
(there are 5 positions having 4,3,2,1,0 common tangents)

First 3 both of you are correct.

The summation in part iv is clearly the original summation minus (9/3^2 + 9/6^2 + 9/9^2...)

But the bit in brackets cancels down to the original summarion also. So the sum in part iv is L - L = 0

I did do that, but i manipulated the summation wrongly... *facepalm*

Thank you for clarifying that Krollo!
