Pаrt III. Free Respоnse Wоrk аll three questiоns below on your own pаper, showing all steps. Label each question and part clearly. Show all work, including all key steps. Answers without supporting work receive no credit. Your work must be legible enough for me to read and follow your reasoning. Use arrows or other notation if needed to make the order of your work clear. FR1. (10 points) Evaluate (displaystylesum_{n=0}^{infty}frac{2}{n^2+3n+2}). FR2. (10 points) Let (mathcal{R}) be the region bounded by the curves (y=2x) and (y=x^2). Use the method of cylindrical shells to find the volume of the solid obtained by rotating (mathcal{R}) about the (y)-axis. FR3. (20 points) Give an exact answer for each of the following. (a) (10 points) A parametric curve has velocity components (x'(t)=dfrac{cos t}{t^2-1}) and (y'(t)=dfrac{sin t}{t^2-1}), (2le tle3). Find the arc length of the curve. (b) (10 points) The curve (y=sqrt{1-x^2}), (0le xle1), is revolved about the (y)-axis. Find the area of the resulting surface by setting up and evaluating a surface area integral.
