Hello everyone! I remember doing these in calc II, but forgot 99% of it. Here is the question: Find the interval of convergence for the given power series. http://cwcsrv11.cwc.psu.edu/webwork2_files/tmp/equations/5e/119a4cd07ce5d3f6f673477ed169641.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://suprfile.com/src/1/4fiy34/lastscan.jpg [Broken] Now i'm confused on what i do now, also u see where i have |x-6|? Is that right or should it be |x+6| ? Alos is it suppose to be the limit as x-> or n->? Thanks! I'm using the ratio test btw.
