Consider the parametric curve r(t) = (z (1), y (1)) = (8 cos (1 7,7), 5 sin (1 - 7:)), & C (0,27]. (x t t t 9 9 Find the set S consisting of all t [0, 2] at which r' (t) is parallel to the line in xy-plane given by x = -58. Answer S = { Answer entry help: Beginning on the left hand side, enter one number in each answer field in the increasing order and without duplication; in case you have fewer numbers than answer fields, enter 999 into each of remaining fields (on the right).
