1. The oblique asymptote is x+1 seeing as you simply divide the top by the bottom.
2. Geometry+ algebra= too lazy to do at `10:28 in the morning.
3. Similar question on our exam last year! use the sin/cosine rule, whichever seems convienient (use sin actually seeing as you only need one length and you know the angle must be acute)

Hopefully that helped you out!

If you divide the top by the bottom you get 6x-4...

(x^3+5x-4)/(x^2-x) = x+1 + (6x-4)/(x^2-x).

Check it.

I know that, but the asymptote is the one that's the.....hmm......the number that's in it completely! The thing on top of the dividing symbol.
That's terribly comprehendable, don't you think.
6x-4 is the leftover, that's why we put it over x^2-x
and I graphed it.....and graphs win!

Yes, and so the oblique asymptote is 6x-4, and NOT x-1...

Or x+1 even.

NO jamie
I actually checked in last year's math notes
it's x-1!!!
And x ordiantes =abisscae..however you spell them, k8t!

Yes yes we talked about this. And I did say NVM. 'Cause I'm silly.

But that would actually put it somewhere around x+1, not -.

yeah, i finally figured that out... but couldn't they just SAY x-coordinates? :-P

No. They have to be RIGOROUSLY STUPID.

OOops MY bad!
see I've been hallucinating recently
I've dreamed things that actually haven't happened
so I tend to doubt that I actually did them in real life now....like saying lunch balconey today? oops. I apologize profusely. I really am very, very sorry.

I might be a bit late.....about 15 minutes into lunch late. (Je peux t'expliquer par telephone si tu veux.) Mais c'est bien.
