If you solve for you get
now substitute this into
and simplify and see what happens.
I´m having a hard time getting through these sum understanding exercises
This one in particular, If you have some idéa, I value some explaining more then solution so please no: Hey stupid, what the hell, just to the "inversetriangular root extraction recursive absolute value differential" method and you got it!! That just makes me even more confused when I dont understand what I am suppose to do.
The troublesome exercise is:
Look at the series of:
of
where
with
and Show that is a geometric series with Constant when =:
where
Here is my current confused work:
Well I figured lets try some different values on and se what happens, then clearly goes towards 3. Well that info could be usefull (I suppose a little sometimes). graph looks like graph shiften left 3 units and up 5 units.
Now lets get on one side and everything else on another and se what happens:
so:
1)
2)
3)
4)
5)
6)
if I set I get
but if I set into the formula it goes
=
And here I am not sure what I´ve done or what I shouldn´t have done...
