5. Consider the series below 1 n² + n 1 n²+n n=1 (a) Use partial fraction decomposition to rewrite as the sum of two rational expressions. Show all steps in the partial fraction decomposition process. (b) Write out the first five partial sums, S₁ through S5. (Hint: Simplify each only as the sum of an integer and a unit fraction.) (c) Use your work from part (b) to find the nth partial sum, Sn. (d) Use your work from part (c) to determine whether the infinite series converges or diverges. If it converges, find its sum.
