Homework Help: calculus

Posted by teamcaridee on Sunday, October 22, 2006 at 6:33pm.

My a.p. calculus teacher doesn't know how to do this problem (like many others) so he's giving us 5 points extra credit on our test if we can figure it out, but I don't know how to do it:
It's as the lim-->infinity
(x+sinx)/(x+cosx)

We know the answer is 1 because it's in the back of the book but do not know how to get that answer. Yeah he ticks me off with not knowing his own material but can anyone help me?

No one has answered this question yet.
