Well, I already know that Riemann proved that a conditionally convergent infinite series can be rearranged to converge to any real number as well as diverge to either positive or minus infinity. But specifically how is this done in an example? For example if I want the alternating harmonic (which "usually" converges to ln(2)) to converge to 5, how can I rearrange the terms?

In addition, does anyone know of any conditionally convergent series that are NOT alternating. It seems to me from the definition that it doesn't always have to be alternating to be conditionally convergent.

i need to find f(x+h)
with the following:
f(x)=6x+2

it is to my understanding that I need to replace the X in the original function with the function of x they are providing me with, thus:

f(x)=6x+2
f(x+h)= 6x+2+h

but the answer in the book is: 6x+6h+2...
and i can't understand why....

Pi.... it means 3.14...etc

It is very obvious that many people think it is irrational.

BUT, the definition of a rational number is that it can be put it in an A over B form.... or a fraction

Pi = 7 over 22 = 7 divided by 22 = 7/22 ....etc

So... rational or irrational... ill ask my Math teacher
