Added example to sec_limit_analytically

[CVollet]

I think the . is a style preference. We just need to be consistent. I don't like it lined up with the fraction bar, but I don't really like it in the denominator either. I can change it back.

I think the period should be after the fraction, not after the 4.

• Evaluate \lim\limits_{x\to 9} \frac{\sqrt{x}-3}{x-9 \text{.}}

Similar with the period. If this is discussion-worthy, let's start a thread in the forum.

The period goes after the fraction. The only question is whether it goes inside \text{.} inside the math, or after the closing m.

It's a bit more than a style preference. In the code it should definitely go outside of the \frac{}{} arguments for screen reader reasons alone. And then there is new MathJax behavior where you can navigate in and out of the structure of the math, and the period shouldn't be in the denominator for someone zeroed in on that denominator.

I wouldn't necessarily object to a period outside of the frac if CSS was somehow able to push it to appear lower.
