Okay I know there are three roots to this equation (from [0,2pi) ):

sin(2x) + sin(x) + 2cos(x) + 1 = 0

two of the roots are:

2.0943951023

and

4.1887902047

What is the third?

I'm a lazy kind of of guy. When I talk about famous people a lot I like to use initials (exe: GWB = George W. Bush, NP = Nanci Pelosi). But I've run into a problem. When I try to use Pres. Obama's initials I always get down marked. BO make me call him "bo" or b.o. which is so obviously racist and BHO brings out the Hussein as his middle name which also makes me racist. And of course if I just use B nobody knows who the f. I'm talking about. So my question is this. Which set of initials should I use to not get thumbed down?

I'm looking at this problem.

(x-27)/(x^1/3 - 3)

And for the life of me I can't remember if this can be simplified. Can I call x^1/3-3 x-27 times two other factors somehow?

I was wondering if Linux has support for either of these formats or at least drivers for the hardware. I think it would be cool if you could have a distro with all of the available software (a.k.a. BSD packages) all on one disk.

anyone tell me the best linux distro to pop on this old piece of machinery. And most importantly some guides to do so. Thanks.
