Question: Calc III Maple Project

Hello, I am completly new to Maple and basically any kind of programing at all. I have a project for my Calc 3 class that consists of 5 problems. And I have absolutley no idea how to get any of them done. I have been sitting in the computer lab at school for almost 4 hours and have made very little progress. Anyways, I was wondering if anyone could help with a coulple of these questions to get me going.

1.Plot the surface 7x + 22xy + 7y + 14xz3 + 14yz3  5z = 180. What is the name
of the surface?

-I have tried just  in the equation and using plut builder but what I came up with looked nothing like what one of my classmates showed me earlier.

3. Plot the surface given by rho =  theta in  spherical coordinates so that it looks exactly like
Figure 1.4.7 on page 31 of the book. (obviously that last part won't help you guys at all)

-I have tried first doing it in rectangular and then converting to shpherical and a couple other different methods but none of them seemed to work.

There are some other problems to but hopefully if learn how to do these, maybe the other ones will make a little more sense. Like I said I have absolutly no exsperience with this kind of stuff and our teacher has given us no instruction on maple ethier and has told us tho just get our hands dirty and figure it out. Well, my hands are pretty dirty and I still havn't figured anything out. PLEASE HELP

Thanks,

David
