. Given the vectorvalued function for curve C as r(t) = (3152, Set, 213), answer the following. (a) Provide an arc length reparametrization of the curve measured from the point (0, 8, 0) moving in the direction of increasing t. (b) Determine the curvature of the function r(t) at a general point (i.e. leave in terms of t). (c) Determine the curvature at the point (0, 8, 0). (d) Determine the normal vector at the point (0, 8, 0)
