Exercise: finding and using Taylor series A. [5 pis] Use the Taylor series centered at r = 0 for to show that the Taylor series centered at r = 0 for is So(k + 1)*+. To earn full credit, you must work entirely in summation notation. B. [5 pts) Use Taylor series to compute lim If the limit is co or -co, make sure to indicate this. Hint: One way to proceed is to utilize the result from Part A by noting that Ar/(1-1)] (1 - x)an( ) sin(s')
