Re: Last Assessment Please Help Me!!
Yes, for the purposes of this calculation, that is okay.
Now combine up the numerator and the denominator.

Re: Last Assessment Please Help Me!!
That is the correct answer. The differentiation will remove the -1 on top and bottom this will make further simplification possible.

let's try this: x[0]=sqrt(5) and x[n+1]=sqrt(5+x[n])

Re: Last Assessment Please Help Me!!
Hi;
Because that is a non linear difference equation is it likey that there is no closed form.
It is easy to calculate what that sequence is converging to.

Hi mantastrike;
Bobbym can you delete this thread please?
Please do not edit a thread starter like that anymore. If you wipe out the initial questions all the remaining math done by others is meaningless.
If I delete this thread I would be deleting a lot of other peoples posts.
What is wrong, maybe there is some other way to fix it.
I have closed the topic.
