Document Summary
Answers: the plane is 2(x 1) + 18(y 2) + 2(z 3) = 0 or, equivalently, 2x + 18y + 2z = 44, (a) there are many possible acceptable answers, including. 1 x (b) the point of intersection is (5/4, 5). (c) two polar representations of the point in (b), one with a positive and one with a neg- ative r, are. 5 17: the curvature when t = 1 is. 73/2 2: (a) the line is x = e2 + e2t, y = e 2. 2 t. (b) the line in (a) intersects the yz-plane at the point (cid:18)0, 2e 2, ln 2 . 2(cid:19) : the area of the triangle is 1.
