III. Let S be the quadric with equation 4x² − (y - 3)² + 4z² = 4. a. What type of quadric is S? Find an equation of the trace of S on the xy-plane, yz-plane, and on the planes y = -1, y = 3, and y = 7. Identify each trace. b. Provide a hand-drawn sketch of S using the traces obtained in (a). Label all important points found on each trace (Note: For graphing purposes √√5 ≈ 2.2). c. The quadric S can also be identified as a surface of revolution. Find a generating curve for S on the yz-plane.
