Thread: Series Converges

Let f be defined by the series for all x where the series converges
A. What is the domain
B. Is f odd, even or neither
C. Assuming that derivatives can be computed term by term show that f'' = f

A. Use ratio test.
B. What about the function ?
C. What have you done?

You in Leache's class?

hahah

Anyway, for A domain should be infinity.
I haven't found an answer for B (could be neither)
and for C http://www.math.sunysb.edu/~disconzi...ging_index.pdf

AHHH HAHA
THANKS This problem is killing me....
