Find the interval of convergence of the power series 8 6 n- x" 11 5 n-+6 Interval notation . An open interval (a, b) should be entered as: i( o(a), o(b) ) . If one (or more ends) of the interval is closed indicate this by using c instead of o, e.g. the interval (a, b] may be entered as: i( o(a), c(b) ) Thus for an interval of (-oo, \\7] you would need to enter: i( o(-infinity), c(sqrt(7)) ) Since, getting the brackets to match when answering this question may be a little tricky, to help you, there is the following template. i( o( ). o( ) ) Grab it with the mouse, paste it in the answer box, fill in each endpoint in the white space of each of ): and change the os to cs where you need to.
