By the root test this would converge absolutly if and diverge if where:
and in this case as as becomes large for all this series diverges.
'find the convergence set of the given power series for the problem'
heres the equation for problem1: http://img297.imageshack.us/img297/9654/untitledsz2.jpg
The hint for the first one is: to use the root test, so how is this done.
thanks for any help.
