(Part A is worth 2 points; Part B is worth 2 points; Part C is worth 3 points; Part B is worth 3 points.) Part A. Determine whether the sequence converges or diverges. If it converges, find its limit. 3 sin(n) + n 3n2 + 5n+ 1 Part B. Determine whether the infinite series converges absolutely, converges conditionally, or diverges. COS(na) iM n2 + 4n + 4 Part C. Determine whether the infinite series converges or diverges. 10 e 2n n=3 Part D. Explain why the integral test cannot be used on the infinite series Le-" cos(n) to determine if it converges or diverges. You must clearly and coherently justify your work - show your steps in your calculation. You cannot provide only the final answer. Circle your final answer for each part
