1. The problem statement, all variables and given/known data Give an example of a power series tha converges on the interval (3,6), but on no larger interval. Give some justification. 2. Relevant equations The equation needed is probably that for a power series: [tex]\Sigma[/tex] cn(x-a)n 3. The attempt at a solution I'm not sure at all. The ratio test maybe, but I don't know where to start. Any pointers would be great.
