Exercise 3. Find and identify the trace of the given quadric surface in the specified plane of coordinates. f) x2 + 2y – 2z2 – 2 = 0, xz-plane. g) x = y2 + 4, xy-plane. a) A + B + * = 1, xy-plane. b) x2 + 4y2 – 4z2 – 16 = 0, xz-plane. c) -4x2 - y2 + z2 = 1, yz-plane. d) x2 + – z2 = 0, yz-plane. e) x2 + x2 – 4y+4= 0,...
Find the mass and the center of mass of the solid E with the given density function p(x,y,z). E lies under the plane z = 3 + x + y and above the region in the xy-plane bounded by the curves y=Vx, y=0, and x=1; p(x,y,z) = 9. Need Help?
(4) Consider the surface z = x2+4y2+1. Suppose you are walking on this surface directly above a curve C in the xy-plane, where the parameterized curve is given by C (t)cost, y(t) sin t. Find the values of t for which you are walking uphil increasing z (Assume you are walking above the curve C in the direction of positive orientation The direction of positive orientation for the plane curve C is indicated by its tangent vectors.)
