## nickymarden limx→1+(x+2)/(x+1) 2 years ago 2 years ago

1. nickymarden

limx→1+(x+2)/(x+1)

2. nickymarden

I just want to know why the numerator became 1

3. nickymarden

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. nickymarden

no $\lim_{x \rightarrow 1}$

6. nickymarden

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

7. DHASHNI

3/2 is the ans!

8. nickymarden

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

9. nickymarden

but thanks :)

10. TuringTest

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

11. nickymarden

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

welcome :)
