Ok. Some questions for you, JG. S(n) = (i=0 to n)Sum ((-1)^i a^i)), |a| < 1 What is this? Can you give me the closed form?
And where do this lead to? S = (n=0 to inf)Sum ((-1)^n a^n)), |a| <1 Can you give me the closed form of this?
Is it the same as the former?
Is it: S(n) = S, or lim S(n) = S, or S(n) = lim S(n), or S = lim S. What do you go for, and what would Euler go for?
