Let y = tan(4x + 4) . Find the differential dy when x = 1 and dx = 0.2. Round to 4 decimal places if needed. Also, find the differential dy when x = 1 and dx = 0.4. Round to 4 decimal places if needed.
(A) dy = 1.3202 for dx = 0.2 and dy = 1.3298 for dx = 0.4
(B) dy = 1.3298 for dx = 0.2 and dy = 1.3202 for dx = 0.4
(C) dy = 0.1860 for dx = 0.2 and dy = 0.0930 for dx = 0.4
(D) dy = 0.0930 for dx = 0.2 and dy = 0.1860 for dx = 0.4
