I have two...(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

The the limit

2. Relevant equations

[itex]\lim_{x \rightarrow 1} \frac{1-cosx}{x^2}[/itex]

3. The attempt at a solution

I figured to just plug in 1, but I wanted to make sure....

1. The problem statement, all variables and given/known data

Find the limit

2. Relevant equations

[itex]\lim_{x \rightarrow 3} \frac{\sqrt{x^2-6x+9}}{x-3}[/itex]

3. The attempt at a solution

I plugged in the 3, and got 3/0, then I got lost...
