HI Alan,
this is beautiful, thank you vwery much.
I do however have 2 questions please...
I would have mistakenly re-written the first term as \(1,5+\sum_{k=3}^{10}{1 \over k}\)
and then from here \(\sum_{k=1}^{10}{1 \over k}-1,5\)
This would have been completely wrong, and would not lead me in any way towards the end?
I have never seen the upper limit changed, as you have done?...Would ytou kindly just explain that to me, and just one thing more: The second term is re-written as \({1 \over k}-1+{1 \over 9}\)
I'm looking hard here but fail to see how you got to that?...Thank you for your time..
