If we wanted to find a power series for f(x) = (x+5)2 we could use the fact that = (x+5)2 a) First, find a power series for: (using the geometric form process) b) If your power series is alternating, make sure to separate the "-1" from the “x" (i.e. E-o (-1)*ax ) c) Expand your power series to the first 5 terms, then differentiate term by term like we did in class. d) Are you able to come up with a sigma notation for your infinite power series? What does it look like? x+5
