Hello everyone, i'm confused (as usual). I think i found the radius of convergence but then waht do i do to find the interval on which it converges? The directions says: Find all the values of x such that the given series would converge. http://cwcsrv11.cwc.psu.edu/webwork2_files/tmp/equations/70/aaf16ffcdb10d6976585856b5dafca1.png [Broken] The series is convergent from x = , left end included (enter Y or N): to x = , right end included (enter Y or N): Here is my work: http://img90.imageshack.us/img90/6637/lastscan5ox.jpg [Broken] Any help would be great! thankss!
