№1.17. Build the surface and to determine their views as well) - 3x2 + 6y2 - z2 - 18 = 0; b) x2 - 2y = - z2.
№2.17. Write the equation and determine the type of the surface obtained by the rotation of the line around the specified axes, make a drawing: a) 2y2 - 5z = 10; Oz; b) y = 2; z = 6; Ox.
№3.17. Build a body bounded by said surfaces: a) z = 3y2; x2 + y2 = 4; z = 0.
b) x + 2y + z 3 = 6; 2x = y; 2x + 3y = 6; y = 0; z = 0.
