1. A certain curve is parametrized by F(t). With this parametrization the unit tangent vector at time t = 1 happens to be <1/V2,0, -1/V2 >. Students in a different class are given more information about the curve and asked to find the unit normal vector at time t = 1 (that is, to find Ñ(1)). The following answers are provided by various students. Only one of the answers is correct. Identify the correct answer, and explain how you know that every other answer is incorrect. A. <0,1 > B. <1,1,1 > C. (1/V1 + 212) < t,0,t> D. < 3/5,4/5,0 > E. <1/13, -1/13,1/13 > F. -1
