Consider the parametric curve r(t) = (800567 111:), 63in( 7 )), t6 [0,21r]. Find the set .9 consisting of ail t E [0, 211'] at which r'(t) is parallel to the line in R2 given by z = 57. Answer 5 = {I H H H I} Answer entry help: Beginning on the left hand side, enter one number in each answer fieid in increasing order and Without duplication: in case you have fewer numbers than answer fields. enter999 into each ofthose fields (an the right). Write my for I\" Write W for z - y (t is required) Write {205(2) for cos 1 (parenthesis are required) Write sqrt(z) for (parenthesis are requtred) Write |n(z) for 11:12 (parenthests are required) Write pi for 1r Write e for 6 Write (arb)*pi for (a/bhr: no spaces Check
