## Cj1213 3 years ago limit of cos x*ln x as x approaches 0+

1. anonymous

what is $\lim_{x\to 0^+}\cos(x)$?

2. Cj1213

times ln (x)

3. anonymous

i am just asking if you know $\lim_{x\to 0^+}\cos(x)$?

4. Cj1213

oh um isnt it just 1

5. anonymous

yes

6. anonymous

since cosine is continuous and $$\cos(0)=1$$

7. anonymous

and what is $$\lim_{x\to 0^+}\ln(x)$$ ?

8. Cj1213

when I did it I got 0 but i wasnt sure if that was right

9. anonymous

oh no it is $$-\infty$$

10. anonymous

so you end up with $$-\infty$$

11. Cj1213

oh okay thanks
