So surely if the question is wrong
Then the solution cannot be correct?

:wink:

Will the original even converge? If not I've wasted a lot of time today :lol:

time is never wasted...
you get more out of a question that took 10 hours of work and you have failed to solve it than spending 5 minutes in a question which you managed.
(Apart from a feel good factor)

if you say so..it got to a point where I couldn't think of another way to rewrite it in the hope of being able to cancel. Oh well - I didnt read further than the second line of the solution so i can go again tomorrow.

Interestingly you can use the same trick as in the extra question to prove that each natural number has a binary representation and it is unique!

Interestingly I do not do pure maths, and I do not quite understand your statement.
Nevertheless I hope someone else finds this bit of information useful in the study of the subject.

Ah fair enough, got a bit over-excited when I realised the same trick was involved; I remember being impressed that you could prove number facts using algebra.
{For clarification, the statement means that every natural number can be written uniquely as the sum of powers of 2}.

Normal was interesting, I think i got there in the end...I wouldn't even know where to start with the DE though....

I hope you got it right
I think the series is 6.

it is not a differential equation as such, since it is satisfied for all f(x)
(it is a differential identity)
it is the equivalent statement to dy/dx = 1/(dx/dy) but for second derivatives.


PS: I have made loads of product operator questions but I thought I give them a day off

I got 6, and Wolfram Alpha agrees. Very satisfying - series are my weakest.
I'll take another look...

Good call, I've seen more of that product operator symbol in the last 2 days then I have in all my life. :wink:

I agree on six, as does my calculator. I have a feeling that I may have overcomplicated a tad (used knowledge way beyond AS).

The differential question looks intriguing. One for tomorrow morning. :tongue:

The series is just an extension of the geometric summation formula proof.

The differentiation result is a beauty.
