1Problem 1(10 pts)(a)(3 pts) Express11-xas a geometric series and write it using the summation notation.What is the interval of convergence of this geometric series?(b)(4 pts) Using the result of Part (a), find the Maclaurin series for12ln1+x1-x, and write itusing the summation notation.(c)(3 pts) Calculate the approximate value ofln119by evaluating the polynomial using onlythe first 2 nonzero terms of the Maclaurin series obtained in Part (b) at an appropriatex.
