8. Using #2, find the Taylor/Maclaurin series expansion for e', where i = v-1, 13 = -1. Use this result to show e'l = cosy + isiny. 9. Design a power series that has (4,8) as its interval of convergence. 10. Find the Taylor/Maclaurin series for way about the point x = 0. Then let x = 1 and check the partial sum of first five terms. Does this appear to converge? Why or why not? Then let x = 2 and again check the partial sum of the first five terms. Does the appear to converge? Why or why not
