So I have written down some notes, and I have forgotten why i wrote what i wrote down.
Find the sum of the series
I wrote down these steps
= x =x* = for abs(x)<1
I don't know how they come about...
they're using power series as functions..got it
thanks for the help there!
I have another question though if you don't mind...Don't want to make another topic
For the maclin series of , after the limit ratio test is
= abs(x)<1. Hence 1 is the radius of convergence. I understand how most of everything comes about, but what i don't understand is why 2n-1 is there. since the original was 1*3*5...(2n-3), shouldn't that be (2n-1)*(2n-2)?
