limx→1+(x+2)/(x+1)

2. anonymous

I just want to know why the numerator became 1

3. anonymous

1/limx→1+x+1 x has to be tending to -1 right?

4. TuringTest

is this$\lim_{x\to1^+}{x+2\over x+1}$?

5. anonymous

no $\lim_{x \rightarrow 1}$

6. anonymous

but i think it's supposed to be $\lim_{x \rightarrow-1}$

7. anonymous

3/2 is the ans!

8. anonymous

but in the books answer it says +$+\infty$

9. anonymous

but thanks :)

10. TuringTest

if x is going to -1 then $$+\infty$$ is certainly the answer

11. anonymous

then i'm right. and there was a typing error. Thank again.

welcome :)
