I wish to see graphs of surfaces in three-space, particularly quadratic surfaces such as ellipsoids and hyperboloids. How would I go about doing this? I tried

Plot3D[x^2/4 + y^2/9 + z^2 == 1, {x, 0, 7}, {y, 0, 7}, {z, 0, 7}]

or

Plot3D[1/3*Sqrt(36-9x^2-4y^2), {x, 0, 4}, {y, 0, 9}]

but I'm not getting anything to work. All of the examples that I can find involve trig functions. Any help?
