№1.26. Build the surface and to determine their views as well) 3x2 - 3y2 - 5z2 + 30 = 0; b) 3z + 2x2 = 0.
№2.26. Write the equation and determine the type of the surface obtained by the rotation of the line around the specified axes, making pattern. a) 2y2 = 7z; 0z; b) 6y2 + 5z2 = 30; Oy.
№3.26. Build a body bounded by said surfaces: a) z = 2x2 + 3y2; z = 0; x = 2; y = 1; x = 0; y = 0.
b) x2 + y2 = 6x; z = 0; z = 2x.
