In Mathematica 7, what is the base equation to type into the program to create a graph of a circle, an ellipse, and a hyperbola.

For example, for a limacon, you would type in "PolarPlot[2 + 2 Cos[x], {x, 0, 2 \[Pi]}]" without the quotes. What would I type for a circle, an ellipse, and a hyperbola?

Thanks!

Is the Japanese girl (Chieko Wataya, played by actress Kinko Kikuchi) in the movie Babel really deaf and mute in real life? I've looked around and I can't find anything that says she is or she isn't.

Thanks!

Hi all,

I have a fantasy baseball draft on CBS tomorrow (head-to-head; basic scoring system) and I was wondering who you would take given these two, Prince Fielder or Ryan Howard. I want great overall production out of the 1st base position so which of these two would be best (I'm assuming Pujols will be gone already)? Please give the reason(s) why you'd go with which one. Right now, I'd probably take Fielder, but I have nothing against Howard.

Thanks!

Hi,

As of just a few days ago, vuze worked fine on my computer (imac) but now, the connection times out and nothing works. It won't connect to anything. I've tried on three different computers, all macs, and they all have the same problem, connection timing out. The vuze website (www.vuze.com) does not work as well on these computers. I tried connecting just to vuze.com on a pc and that worked, but it didn't work on any of the three macs; I have not tried using the actual program on a pc though. This problem just started a few days ago, it worked fine before then.

Please offer any suggestions or help!

(Please, no comments about "macs suck" or "pc's are better" I just want a solution)

Thanks all!

The monitor is the Samsung T240HD. I linked the newegg site at the bottom.

The ps3 would use an HDMI cable, while the macbook pro would use the dvi port.

Hi!

What monitor would be able to run my ps3 at full 1080p (does not need to have speakers) and my macbook pro? I would prefer using an HDMI cable for the ps3 and a dvi cable for the macbook pro. I would need it to be at least 24" and the cheaper, the better.

Thanks!

In Killzone 2 MP, if you quit before you finish the overall round, do your points get deleted? Also, how do you tell how many missions are left in the game before the overall round ends?

I want to buy one of those two games, and I am not sure which one is better. Also, if I buy one, can I use the instruments to play on the other one, ie: use ghwt's instruments on rb2?
