Each of the 12 questions is worth 10 points. Please Write your solution to each of the 12 questions on a separate sheet of paper with your name and your TA’s name on it. Please put a box around the ﬁnal answer. To maximize credit, please show your work, and if you have extra time, double check that you got the correct answer and didn’t misunderstand the question. Good luck! 1. Let r(t) be a parametrized curve in the m, 3; plane satisfying r(0) = (1, 2) and r’(0) = (3, 4). Let f(:c,y) = 6”. Calculate d Warmth. 2.
