Question 11 A 2 In this question you may round each entry to the nearest hundredth where necessary. I' ( t ) In parts (b) and (c), note that we can measure the curvature of a curve with k(t) = IT' (t ) | The curve shown above in the xy plane is given by r(t) = a) Compute T(3) and N(3) T (3 ) N(3) b) What is the curvature of the above curve when t = 3? k (3) = c) What is the maximum curvature for this curve? kmax
