A particle moves along a parametrized curve r(t) in space. Find r(to) at the instant when the following facts are given for vectors: The instantaneous radius of curvature when t = to is p(to) = 6 m, The unit normal vector when t = to is N(to) = (5, -4, 2), The coordinates of the center of the osculating circle when t = to are (11, -5, 3).
