```Hello at Math Group!

Unfortunately, I am not very skilled with Mathematica, and have been
assigned a few problems for Calculus 3.  I'm been working on these for
hours and I'm just absolutely stumped on the last two.  None of my
classmates have been able to solve it either, so I was searching for
something to help me and I found you!  This assignment is due tomorrow,
and so I guess I'm kind of just keeping my fingers crossed that you guys
may be reading this at 12:30 am.

I really hope this is like a super-easy problem for you...

The problems are:

Graph the hyperboloid of one-sheet:  (x^2 / 16) + (y^2 / 4) - z^2 = 1

Graph the hyperboloid of "one-sheet" (it's written as one sheet on the
page, but based on the equation I believe that's just a typo and it's of
two-sheets):  (x^2 / 16) - (y^2 / 4) - z^2 = 1
